Quite a simple question really, which was already mentioned in the title of the thread. What do you believe to be the best tablet? A 16 GB Nexus 7 WiFi model or a 16 GB Nexus 10 WiFi model?
Hmm...

Kind of an odd question really. Clearly the 10 has better specs, including screen.
But I'm pretty sure many of us bought a Nexus 7 because it was 7 inches portable. So, I'm pretty confident saying that the Nexus 7 is a better 7 inch tab than the 10 is.

Well, it is obvious that the Nexus 7 (which is a 7" tab) is better at being a 7" tablet than a Nexus 10 (which isn't a 7" tab, but a 10" one). However, isn't the Nexus 10 only a dual-core processor? I know the screen resolution is quite amazing, but besides that isn't it actually worse?
CPU: http://www.arm.com/products/processors/cortex-a/cortex-a15.php
GPU: http://www.arm.com/products/multimedia/mali-graphics-hardware/mali-t604.php
CPU core count isn't all that matters. I don't have any real-world benchmarks, but I'm pretty sure that CPU alone can execute tasks faster and better than the Tegra 3. And since the GPU and CPU aren't on the same chip (that I know of), that also comes with it's share of better performance.

This ^.
You cant really justify which is better becuase the size difference. Like the first poster said we all bought this for the form factor. So to us the N7 is better regardless of the specs. However spec wise... i would go with the N10.
Two completely different forms factors and uses. They are both great devices.
CPU in the N10 is about twice as fast as the best A9 (S4 Pro) out now. It is more than likely about 3-4 times faster than the T3.
Two different devices for different purposes, its like comparing a motor bike to a car

It is like asking: 'What is the best: a semi or a van?'
Those 2 tablets are just in a different market, ergo not comparable.
If you don't take the size in the comparison, the Nexus 10 would win: more efficient/faster processor, way better grafics, almost quadripple resolution, ..etc.
By specs, N10 destroys the N7.
In terms of pure performance, which one is better?
The Nexus 10 is a dual core vs Tegra 3 Quad core.
2gb ram vs 1gb ram.
Also take in consideration Tegra Zone support, although not really related to performance. The Tegra 3 gets larger list of premium games.

It isn't even a comparison. The N10 slaughters the N7. Pros vs joes if you will.
I'd still keep my 7". It performs just fine for what I need it for. 10" is too big. I'm more comfortable with my laptop at that point.

You are confused.
The Tegra is a System-on-Chip ("SoC") that has both CPU and GPU cores on the same die. The CPU complex has four A9 ARM cores, plus a fifth "ninja" A7 core. The GPU has 12 cores, plus a number of special functional units. All cores access the shared RAM through a single memory controller.
The CPU complex spends most of its time running only the power-optimized "ninja" core, with the other cores powered off. The ninja CPU has a simpler A7 core and is implemented with power-optimized low-leakage transistors. (The A7 core does less speculative work, and thus is more power efficient than the A9 cores even taking into account the extra clock cycles needed.) If the workload increases, the main cores are powered up and execution is switched over, with the ninja core left idle in a low power mode.
The GPU complex has 12 general execution units, but these aren't directly comparable to CPU cores. You can't even compare them to the "cores" in other types of GPUs. In addition, there are other special units such as video and audio decoders in the GPU complex. These operations could be done on the main CPU or, sometimes, the GPU. But they are common and power-hungry enough to get hard-wired logic.
All of this complexity makes it really difficult to benchmark and compare. Or really easy, if your goal is to make one product look faster than another.
The Tegra is carefully tuned to do HD video decode with only the ninja core and GPU turned on, thus consuming little power. There is just enough CPU time left over to supervise the cellular modem for housekeeping operations, or do other trivial tasks. But if you add in just a little application work, the main four cores are activated and power usage goes way up.
Another way to skew the test result is to pick specific micro benchmarks. The Apple A5 (which is unrelated to the ARM numbers e.g. A7 and A9) was designed for a high resolution screen, and knowing that many early apps would be iPhone apps with pixel doubling. They put extra gates to increase the pixel fill rate and smoothing performance. This resulted in a bigger chip, but better performance with modest power use for these functions.
My estimation: The Nexus 7 with Tegra 3 is faster, has the potential to be more power efficient, and will have better long-term support and improvements. The N10 has the big advantage of 2GB of memory, which may become important with future versions of Android.

Best answer I've seen.
And has been said before, surely, in the end it comes down to what do you want to do with it. I prefer my n7 because 10" tablets are simply too big and uncomfortable

Real world experience will require the device in hand. The resolution being pushed will need a lot more backbone to provide the same smooth experience as the lower resolution device. Just look at the iPad 2 vs 3. The iPad 2 felt like a better experience because of the lower resolution. Most people couldn't even tell the two apart or correctly identify which was one or the other.
Resolution that high is retarded on a 10" screen. Waste of battery and resources.

I agree.A super display is great if everything is built to look good on it but not if it comes at too big of cost in performance.That is what happened to the ipad 3.They made a good device pretty, but slow.On a small screen most can't tell the difference in dvd quality and full hd.Both would look good but one would smoke the other with the same hardware doing other things. jmo

Keep in mind why the iPad has pointlessly high resolution. It wasn't that Apple wanted to provide an exceptional experience. It was that the underlying software wasn't designed for different screen sizes and proportions. They had a choice between redesigning the API combined with converting apps, or making the screen exactly double the number of pixels in each direction. Apple's big market advantage was the higher app count, and many apps wouldn't be converted to a new interface ("walking dead" / will never be updated). So they went with a hardware solution, and marketed the "retina display" as a plus rather than a work-around for a primitive API. (A replay of the Mac ROM holding back OS improvements.)
Ofcourse specs wise N10 wins..But N10 lacks some features like its only WIFI no 3G/2G !!! it will be tough for my country .

Since the launch of SGS3 is around the corner and the next note will probably come within next few months, I thought of starting this thread to know how many users prefer having Quad Exynos 4 ( similar to SGS3 which is based on A9 arcitecture with Mali 400 GPU built using 32nm manufacturing process) or dual Exynos 5 (A15 architecture with Mali T604 GPU which is based on probably 28nm manufacturing process)in our next Note...
Cast your votes in the poll
You should put a POLL, it would get more people interested. But for me, I'd rather get the A15 with the Mali 604T since A15 is supposedly to be 40% faster than A9 and the Mali 604T will blow the Mali 400 away.
Definitely the dual A15 with Mali 604. No doubt.

Quad! I don't care if I don't use it, and I don't care if I don't need it.
It just feels good to have that much power in the palm of your hand.
I'll benefit from that much power since I play games and I look forward to more capable emulators in the future.
I don't give a CRAP about the amount of cores!
I want the most speed that's possible, if that would be with dthe dual i take that, if it's with de quad, then thats my way to go...
Can't vote in the poll because i want speed, and since it's not sure wich one is faster i can't vote!
PS
I think the Exynos 5 will be released @ the end of this year, and the Exynos 4 tomorow
If that's correct i go with the Exynos 4, i hate waiting
what the note lacks is a decent GPU. the current GPU can't efficiently handle the 1280x800 pixels. however what i want more than anything is 1. non-pentile screen that is FLAWLESS and 2. a bigger battery still ~3000 mAh like the RAZR max. I would gladly sacrifice a few mm for a larger battery. I find it stupid how HTC decided to go with a slim and NON-REMOVABLE battery and storage to save a few mm. Seriously? This is why HTC is falling in a deep pit.
Exynos 5 dual, it has more power and is more efficient

EASILY the A15 with the T-604! Come to papa!
The fastest clock speed and the best GPU is all that matters. 2.2 ghz 2 core with a fab GPU will blow away a 10 core 1.0 ghz with a bad gpu everyday every way.
How about the beast Quad Core A15 Exynos 5450 with Mali T-658? Ok, ok, I know technically it hasn't been built yet and will probably be for tablets, but wouldn't mind seeing it in the Note since it is a tab/phone hybrid.
But as for the current SoC's available now, I would take the A15 dual Exynos 5250 with Mali T-604.
More likely, I think Samsung's road map would be to release the flagship Galaxy S lines (in this case the GS 3) with the latest SoC's, then the next Note (Note 2 in this case) would get a slight spec bump based on the Galaxy S 3 with a faster clocked CPU/GPU combo of the Galaxy S 3 line 6 months later, then the GS4 would get next Gen SoCs with the Note 3 getting a spec bump of the GS 4 SoCs, etc.....
I am sorry.. but this amounts to techie circle jerking..
Quad core processors came out for the PC when not a single application could even use two cores, much less four.. Even today, several years later, for the very very vast majority of applications, it is hard to get a PC to run more that one and a bit processors.. My i7 snoozes, and even cranking up real time low latency audio(a stressful activity)it runs 2 processors at 30% and one at 5%
Therefore I frankly do not care if they put a hamster and a wheel inside the device...as long as the results in operation of the device meets my needs.
So, given my customer needs are for smoother, faster and more reliable operation with better battery life and an enhanced user experience, Samsung can put whatever they want into the device...
In saying that, decisions by the majority of folks are driven by what they think the specifications mean, rather than the impact or result of those specifications in real life usage, so while i am sure its not necessary, a next Note will for sure have a quad core.
With a single core my galaxy s with ics is snappier than my note. Finally its the software I guess.

I agree. Android multitasking would need to be vastly different than what it is today, and on top of this the RAM specs need a major bump to even begin to show advantages in multi-core processing.
Also like you said, it has not mattered for deskptops and laptops what the real-world benefits are, just what the consumer feels about the value in their purchase. Nowadays it seems people are more concerned with the number of cores as opposed to the clock speed.
I do like the approach that Ti has taken with the OMAP in dedicating low-power cores to low-power functions, and feel that it really has potential in mobile devices, but they seem to be a step behind when it comes to the bigger tasks of mobile processing. Intel being on the cusp of Haswell has me excited to see what they can do in this territory.
Dual Exynos 5 for me at the moment.
It'll be interesting to see how they market this dual core a15 processor because joe public, will always think more cores is better. I do feel though that the note 2 might not have the same internals as the s3, like our notes had the same as the s2. For the note they seemed to put in all the best tech they had on offer at the tine, so if the a15 is ready to go by November time then I think they'll defo use it unless something better is available.
Dual core with speed.
Quad cores mean squat if they slow the primary usage down.
I'd rather get a dual than a quad even if its on the same generation and process so long as it is clocked higher. Give me a smaller process, newer gen chip and better gpu? There is no choice.
Id go for the i7 3960x and gtx 690 if they can squeeze that in the next note but I think I wont get a choice and will just end up with whatever Samsung puts into the note 2.

I agree with you....the main reason I created this thread, because I wanted to know how many members actually know the effect of system architecture and the manufacturing process will affect the day to day performance of the device, battery consumption etc.,it was never about the software but I know it everything comes to the OS how deeply it is integrated with the hardware and how effectively it co-ordinates with them...this is why Apple's devices are snappier than the android...the problem here is Samsung is more concerned about bringing more devices out than focusing on the system's deep integration...so it only comes to the fact that the thread is only about the hardware... but the discussion about the embedded systems is also welcomed....

Hi there!
I am in the hunt for a 7"-8" Android 4/4.1 tablet. Currently my choices are the new Acer Iconia A110 (because of a microSD card slot), the Motorola Xoom 2 Media Edition (because of the bigger screen, excellent build and virtual surround sound), the Samsung Galaxy Tab 7.7 (again with a slightly bigger screen, a microSD card slot and an excellent AMOLED screen) and the top dog Google Nexus 7. But i am more interested with the Nexus 7 in terms of "Is it worth the investment" even on a small screen?. I will be using the thing mainly for checking email/news/weather, the usual Youtube, WIkipedia, Twitter, watching movies and also gaming. So, i'd like to ask:
1, Is the actual GPU dual or single channel? And what's the frequency? Does it matter?
2. Is the 1.3Ghz the base CPU speed? Or is it underclocked like what Apple is doing with its tabs?
3. Aside from connecting a mice or keyboard what other stuff can the Bluetooth 3.0 standard do?
4. Is it capable of wireless file transfer to & from a Macbook?
5. I'm aware that it doesn't have Flash but can i still install them via the Google Play?
6. Are they stereo speakers? Capable of surround sound? (some sound issues in some models i heard)
Please advice. Thanks.

Would it matter if a tablet has dual or single channel GPU? Does it matter if the wifi is dual or single band? WIll it actually help make the graphics "better" and surfing the net faster?
Would you trust Acer when it comes to build quality of its tablets compared to say samsung or Motorola?
1. Not sure(I think I heard about it being overclocked somewhere)
2. Default is 1.2ghz, can be overclocked up to 1.5ghz.
3. For example: File transfer. If you root you can also use it as a PlayStation controller with BluePutDroid.
4. There are a number of ways to do this, I would recommend AirDroid.
5. To get flash(no root required):
A. Go to settings->security and enable unknown sources.
B. Download and install the flash apk on your device from here: http://forum.xda-developers.com/showthread.php?t=1763805
C. Get a browser that supports flash like boat browser(from play store).
6. Stereo, probably not surround sound.

Not sure what dual channel GPU means to tell you the truth.
I believe the nexus 7 has dual channel WiFi, using speed test app the speed reaches or goes above my maximum speed from the other end of the house.

There is no such thing as a single or dual channel GPU. Channels refers to the RAM. It is a 12 core GPU.
1.3ghz is the maximum clock speed of the specific CPU used, the T30L. It is not underclocked.
this is the truth after reading some ****.no single or dual gpu.12 core has.channel intended only for the ram.this is the minor tegra3 out there,less freq. clock but high clocked ram and not the same as t30 packed.begginnning with the fact the clock cpu freq. is overcloccable without problems,the ram packed on n7 is IMHO better than ad example tf201 or htconex one's
Are you guys certain there is no such thing as single or dual channel CPU?
And If the GPU clocked speed is 1.3Ghz would it mean that there is 1.3Ghz on each of the 12 cores?

no you are wrong man.the CPU(4cores) is clocked at 1.3 ghz (4 cores running) and 1.5 (or 1.4 i don't remeber)in single mode (1 core running)
the GPU (12cores)is clocked at 416 mhz by default
apart them,if you flash a custom kernel,this Soc can reach (depending on tab,they aren't exactly the same chips)1.8\2.0 ghz for the CPU,and 484\520\600\650\700\750 with the GPU (here depending on tab as well)
I see. So, it is fast?
As a side question would it be practical to buy a new or latest tablet like the Nexus 7 than an older (and equally good in its own) say Galaxy Tab 7.7 or the Xoom 2 Media Edition? What i'm trying to ask here is the "problem" of compatibility with apps and games if a tab has an older GPU in them.
Would that be an issue or not?
yes,sure it's fast!a little bit faster than others with same chip.i do you an example regards the last question.
there are peoples with old gpus,that continue playing hd games with these old gpu without problems (not all games working,but many of them!).an example is the galaxy nexus that i own,it 's packed with a good cpu and a old gpu,that we found also on galaxy s,nexus s ecc,but honestly i never found a game that doesn't work for the odl gpu.i have also tegra2 devices,no prob with games,surely a tegra3 is more powerfull and you can play games with full effect enabled without problems.all apps works,not depending to gpu,but only the version of OS at least.
The Tegra 3 SoC only has a single channel memory. Specs are 1GB RAM of DDR3L -1333 MHz (Low Voltage) giving a total memory bandwidth of 5.3 GB/s, is this super fast, no, but it is more than than sufficient for the Nexus 7 display resolution.
To the OP, don't get stressed about specs, especially if you're 100% sure what they actually mean. The important part is user experience of the Nexus 7, due in part to Android Jelly Bean, it is smooth and enjoyable, it can play all the latest games well, I also run Playstation & N64 emulators on it without issue.
Finally, The Nexus 7 is fully unlockable, so it has great developer support on XDA and other forums, which is 50% of the device's appeal in my eyes. If you can wait a few weeks, the rumour is a 32 GB model will replace the current 16 GB version.
If you can manage to find a Nexus 7 used on Craigs or Ebay, I would do it. I got my perfect condition barely used 16gb for $160 from a buyer's remorse user on Craigslist. For this price I find the tablet to be very good. I would have a harder time paying the $250 plus tax in store for the same unit. Not that it's not worth the $250 but already owning a Galaxy S3 phone, it's too much of the same at the end of the day, much like I experienced when I had a iPhone and iPad together.
The Nexus7 for me is a great grab and go device for quick browsing, game playing, weather checking, etc.
If you've got to have the latest and fastest specs, the Tegra3 is getting dated already and you'd want to find something with a Qualcomm S4 chip (even this isn't really faster than Tegra3). Supposedly the OMAP 4470 in the bigger Fire HD and the Nook HD+ might be a little faster for more money.
i doubt 4470 it's faster than tegra3 (all 3 variant)..it's basically a 4460 with a bit more clock freq.,same 45nm tecnology and with a faster gpu (with dedicated 2d hw chipset).they claim it's up to 2 times more faster than sgx540.if it's true,i think that tegra3 is better (not for the quad).Anyway i have to agree with all the things sad in previous posts.OP don't care about spec,a nexus device is fast for many others things that i don't write,already sad,and also if tegra3 it's becoming an "old" chipset compared to new out this days,it performs very well with an optimized OS.wait for the 32gb version and never ever think only about cpu\gpu specs :good:

A full fat OMAP 4470 is faster than the Tegra 3. I read a review of the Archos 101 XS which runs an OMAP 4470 @ 1.5 GHz (GPU 384 MHz)
In the ultra demanding GL Benchmark 2.5 - Egypt HD (Offscreen 1080p)
Nexus 7 = 8.9 FPS
Archos = 11 FPS
Transformer Infinity = 11 FPS
There is scope for the 4470 to run at 1.8 GHz, but that is probably only for larger devices like Windows RT tablet, Amazon apparently have clocked it at 1.5 GHz. Overall in a tough benchmark the N7 is slower, however the Transformer Infinity is the same speed, which is basically as fast as an easily overclocked Nexus. As the OMAP is a dual-core, in theory a game developed specially for our Nexus (Tegra Zone?) could be faster or more feature packed in terms of physics etc, if it use all 4 cores.

months ago the 4470 was supposed to run at 1.7 ghz.i remember when i bought the gnex in november 2011 that 4430 is at 1.2\4460 at 1.5\4470 at 1.7.theese number was in the official omap site and guide line referments.only after being out the fact of the 4460 bug (major part of them,wasn't capable of 1.5 ghz,and this Soc it isn't a downclocked one,from 1.5 to 1.2 by google.it's a 1.2 cpu.)they change also in the site some numbers.now the 4460 is at 1.2 and the 4470 there's write 1.3+,in this case of the archos 1.5.what a strange thing from omap!i saw same anandtech reviwe like you sad times ago,but honestly i think that in the total of bench that regularly they do,there are some in favor of 4470,and some in favor of tegra3,at least depending also if referred to cpu or gpu.with 4460 they did a good job,i really like it,but after have a look at 4460\70 documentation,seems that in term of cpu,there aren't so much differences.if i clock my 4460 at 1.5\16,do a bench and compare with a same bench do with a 4470,i think that the most differences are gpu related..and when i compare my bench with n7 and gnex,in term of cpu and both ultra-tweaked i see a big gap in scores...it's for that i continue to think in the total user exp and bench scores as well tegra3 remain more powerfull.but certainly the differences aren't visible by end user..but with bench at least and in th end what really count it's how's the user experience,not bench

An area the 4470 does hold a significant advantage over Tegra 3 is memory bandwidth, as it utilises dual-channel memory, hopefully Tegra 4 will sort out that deficiency. Ultimately the OMAP's GPU is not powerful enough to be bandwidth limited anyway, overall I like the Tegra 3 from a UX perspective, looking forward to a Tegra 4 in the next Nexus 7 v2:good:
Using a nexus 7 now. Very happy with the money I paid for it. In terms of spec? This beast will last you for awhile. Even if they are pushing specs already to the next level, it'll be a long time until a quad core 1 gb ram machine will be considered slow.
Simply put, at this price and quality, anyone can buy it and everyone should.

Finally, The Nexus 7 is fully unlockable, so it has great developer support on XDA and other forums, which is 50% of the device's appeal in my eyes. If you can wait a few weeks, the rumour is a 32 GB model will replace the current 16 GB version.

The 32 gig will be replacing the 8 gig model. Two versions will be available by Christmas: a 16 gig model and a 32 gig model. The 16 will be priced at (or below) $200.00. The 32 will be at (or below) $250.00.

You have a link confirming that, or is that inside knowledge
It's the logic step for Google. The 32 gig is already being sold and nobody really wants the 8 gig model. To compete with the "other" tablets and to make up for the lack of an SD card slot, it only makes sense.
IOW.....my speculation from 40 years of computer use....starting with the Heathkit H8.

They've unveiled it today
http://www.engadget.com/2013/01/06/nvidia-tegra-4-official/
and apparently it's much powerful and faster than the eqynox on the nexus 10, but I don't know that much about this kind of tech, I'm probably finally going to buy the Nexus 10 this week if Samsung doesn't unveil a more powerful tablet, so I was wondering if this Tegra 4 processor is worth waiting for until it's implemented on a tablet.
May TEGRA 3 Rest in Peace ...

Their browser test is having the Nexus 10 run Chrome while the Tegra runs AOSP. In my eyes that makes it a 100% unfair comparison.
Between bad experiences with Tegra 2 and 3 (Atrix/TF700) and their requirement that Tegra optimized games not run on other SoC vendors without any real reason other than because they can, I cant even consider a mobile Nvidia device. All they're good for is keeping the more reputable chip makers on their toes.
yes it's nice
Would be interesting to see this with both devices running the AOSP browser! From my experience it is much faster than the current chrome version (which still is version 18 on android, compared to 23 on desktop). Maybe the Tegra4 would be faster aswell, but not that much.
Everything on my N10 is extremely fast and fluid, so I wouldn't wait for whenever the first Tegra4 devices will be available. Plus its Nexus so you know what you are buying!

Agreed, they're making an Apples and Pears comparison that was undoubtedly set to show the new processor in a good light. It's only to be expected, it is a sales pitch after all. It will no doubt be a faster chip though.

I would much rather see a couple benchmark runs myself. A time comparison of a web browser is no way to test the power of a new chipset.
Still, I would expect Tegra 4 to be WAY WAY WAY more powerful than the Exynos 5250. Both devices use the A15 architecture, and Tegra 4 has twice as many CPU cores as we have. This alone is already a big boost in multithreaded apps. Then look at the GPU where you cant even compare the two at all except by end result numbers. They are just far too different. We have 4 GPU cores, Tegra 4 has 72 GPU cores. But those cores are designed far differently and not nearly as powerful per core. It is all about the companies definition of what a GPU "core" is. And then you have a smaller process node as well, which by itself already promises to use less power than the larger process node the Exynos 5250 uses.
I would honestly expect the Tegra 4 chipset to completely destroy our tablet in terms of performance, but a much more fair comparison would be to compare the Tegra 4 to the Exynos 5 quad. Those two are actually designed to compete with each other.
If you want to compare exynos and tegra 4 then wait for exynos 5450 (quad a15) which should come with galaxy s4 no of cores makes a difference here t4 is quad but early gl benchmarks show that A6X and exynos 5250 have a better GPU

So far this Vizio 10" was the most exciting Android development out of CES. We have few more our of Press events scheduled in Vegas and then it will be all over

The new iPhone 5 doesnt use the same ARM architecture are the S3 though, it is a custom design. So those can be compared against each other fine to see which architecture is better. And if a slower clock speed CPU gets better scores then we know it is a superior design. This is the basis of all benchmarking. If we were only allowed to compare the exact same architectures together then we wouldnt learn anything.
Tegra4 uses a (probably slightly modified) A15 core, and the Exynos 5xxx uses a fairly stock A15 core. So a higher clocked A15 should beat out a lower clocked A15 in a direct comparison no matter what. Then when you throw 2 additional cores on top it should always win in multithreaded benchmarks too. Seems pretty common sense to me.
The main difference will be in the graphics side of things, where Nvidia has their own designed GPU compared to Samsung's use of the Mali GPU's.
You can still compare them together just fine, it just need to be both of them on the same browser if there is a browser comparison being done. In this PR release, Nvidia skewed the results like all companies do. So we cant really see the difference between the two from those pictures and we need to wait for 3rd party review sites to do proper testing to see actual results. Yet we can still estimate performance plenty fine since we have a baseline of the architecture already with this tablet.
"Tegra 4 more powerful than Nexus 10"... well duh! It's a new chip just unveiled by nvidia that won't show up in any on sale devices for at least a couple of months. Tablet and smartphone tech is moving very quickly at the moment, nvidia will hold the android performance crown for a couple of months and then someone (probably samsung or qualcomm) will come along with something even more powerful. Such is the nature of the tablet/smartphone market. People that hold off on buying because there is something better on the horizon will be waiting forever because there will always be a better device just a few months down the line!

That was kind of his point.
I don't think anyone is denying that the tegra will be faster. What's being disputed here is just how much faster it is. Personally, I don't think it'll be enough to notice in everyday use. Twice the cores does not automatically a faster CPU make, you need software that can properly take advantage and even then is not a huge plus in everyday tasks. Also, in the past Nvidia has made pretty crappy chips due to compromise. Good example being how the tegra 2 lacked neon support. The only concrete advantages I see are more cores and a higher clock rate.
Based on the hype : performance ratio of both Tegra 2 & 3 I wouldn't have high hopes until I see legit benchmark results.
What does seem promising though, is the fact that they are making more significant changes than from T2 to T3, such as dual channel memory (finally after 1-2 years of all other SoCs having it -.-) and the GPU cores are different too.
Still, the GPU has always been the weakest point of Tegra, so I still don't think it can beat an overclocked T-604 by much, even though this time around they will not be the first ones to debut a next-gen SoC. Given the A15 architecture they can't really screw up the CPU even if they wanted to, so that should be significantly faster than the Exynos 5 Dual.
I've also just read this article on Anandtech about power consumption and the SoC in the Nexus 10 consumes multiple times as much power as other tablet chipsets, making me wonder how nVidia plans to solve the battery life issue with 2 times as many cores and a (seemingly) beefier GPU, not even mentioning implementation in phones..

Apparently this is the tablet that comes to take Nexus 10 spot, Vizio 10 inch tablet with Tegra 4, 2560 x 1600 resolution, 32gb storage, Android 4.2. And it should be coming out Q1 2013, I think this one makes me wait to hear some more about it until I buy the Nexus 10, although to be honest the brand is a bit of a let down for me.
Edit: the 10-inch model, key specs (aside from Tegra 4) include a 2,560 x 1,600 display, 32GB of on-board memory, NFC and dual 5MP / 1.3MP cameras.

Which processow will be better, Exynos 5 Octa or A simple Snapdragon 600 quad?
In my POV, Octa will be useless since it will be a battery hog and no apps really use that much cores and power. The S600 will be more efficient for day-to-day use since it consumes less power and will actually be used.

[Info] Exynos Octa and why you need to stop the drama about the 8 cores
AndreiLux said:
Misconception #1: Samsung didn't design this, ARM did. This is not some stupid marketing gimmick.
Misconception #2: You DON'T need to have all 8 cores online, actually, only maximum 4 cores will ever be online at the same time.
Misconception #3: If the workload is thread-light, just as we did hot-plugging on previous CPUs, big.LITTLE pairs will simply remain offline under such light loads. There is no wasted power with power-gating.
Misconception #4: As mentioned, each pair can switch independently of other pairs. It's not he whole cluster who switches between A15 and A7 cores. You can have only a single A15 online, together with two A7's, while the fourth pair is completely offline.
Misconception #5: The two clusters have their own frequency planes. This means A15 cores all run on one frequency while the A7 cores can be running on another. However, inside of the frequency planes, all cores run at the same frequency, meaning there is only one frequency for all cores of a type at a time.

I hope that the overclocking or higher clock rate doesn't produce Moment-esque results.

In the US that is true, they are both S600's, with the S4 having a .2ghz higher clockspeed. Many of the other S4's will have the Octa Exynos chip.

Ah. I see. Different hardware for different regions. Like the One X.
Even though it's eight cores it is probably complete overkill. Yet another bigger number to put on marketing. How many apps will actually use that? How many apps use four cores at the moment?
There have been some articles about multiple cores being more for point of sale than for the end user. Even if you're signing up for a contract right now I doubt that much would be making use of it in two years time. So, the future proofing argument is moot.
It'll be interesting to see. Of course the galaxy builds of Android will use the cores. With things like the stay awake feature and pip it is useful. Outside of the OS I can't see it being necessary.

The "octa" core processor is complete bullsh*t. Imo, 2/4 cores are perfectly fine as long as they optimize it and perfect the hardware, why stack 8 cores when only 4 work at one time and no app will use all that power.
They should've focused on design to make it look less like a toy phone and use better finish, instead.
Oh the marketing..
Not HTC or whatever fanboy, just stating my opinion.

Very good read, thanks for taking the time to post it. Surprised no-one has mentioned that we need this in our Ones. Would certainly help with the battery.

"Octa" is not gimmicky or for marketing.
Octa is the name of the SoC, and how it was named is nothing wrong
There are 3 implementations can be used, and one with maximum 8 cores running at the same time.
GS4 doesn't use that impletations, but it does not mean the SoC cannot be "Octa". You have a house with 8 rooms but you know to open or you wanna open 4 rooms only, the house is still an 8-room house.

How do you know all 8 can run at the same time? Has Samsung demonstrated that already? Any links?
Also what would be the speed if all 8 are running at the same time?
Also did you see that an Intel dual core @2GHz beat the Exynos Octa in benchmarks!!! So all 8 cores running at slower speed might not be very good actually. It might even slow down things even more...
We recently demonstrated a dual core running at 3GHz at MWC in Barcelona. That chip was able to load games at crazy speeds. A game that took 15s to load on existing Exynos Quad core was loading in just 6s with our chip!

Its all about bragging rights really. Same as Samsung is doing with regards to Octa.
The the chip that could run at 3GHz could also very well run at 1GHz at just 0.6V (so consuming far lesser power than anything else in the market). A dual core at 1GHz is still good enough for all mundane tasks like playing videos or internet browsing etc. So in practice it would have been a very efficient solution. It was a real innovation really. Sadly the company did not have money to pour more funds into the program and has shut it.
It was demonstrated at Mobile World Congress in Barcelona in february this year.
Anyway point is, we did not need extra set of power efficient cores like Samsung is doing. We ran the same cores that could do crazy high speeds and even crazier power efficient mode! Thats a very neat solution.
Heres a press link: http://www.itproportal.com/2013/02/25/mwc-2013-exclusive-dual-core-st-ericsson-novathor-l8580-soc-crushes-competition-benchmarks/
To quote the article:
A continuous running test monitored by an infra-red reader showed that the 3GHz prototype smartphone remained cooler as it uses less energy and in some scenarios, it could add up to five hours battery life in a normal usage scenario

"Octa" is not gimmicky or for marketing.
Octa is the name of the SoC, and how it was named is nothing wrong
There are 3 implementations can be used, and one with maximum 8 cores running at the same time.
GS4 doesn't use that impletations, but it does not mean the SoC cannot be "Octa". You have a house with 8 rooms but you know to open or you wanna open 4 rooms only, the house is still an 8-room house.

Actually, no. At least not in my opinion. Octacore means 8 cpu cores on one cpu-chip.
I would see it like this:
You have 2 houses on your lawn which are beside each other. Every house has 4 rooms. You have to switch houses to open up the rooms. Just like the Exynos "Octa" has to, since it cannot run both CPU's at the same time.
If you are in a house with 8 rooms, you cannot simply be in all 8 rooms at once. You can connect the open doors between all the rooms, and since your in that house, you can freely walk in every room. But not with that implementation.
I wouldn't call the Exynos "Octa" an Octacore, its a dual CPU system with a 2x4 cores, with the difference that regular desktop dual CPU systems can use both CPU units at once, but not like the Exynos "Octa". Still, dual quad system comes closer than a pure octacore system.
This is kind of a hybrid. Nice technology for a mobile device, but at the same time, kind of unneeded / inefficient, compared to regular quadcore systems. Even the Tegra 3 system with 4 active cores and 1 companion core for standby tasks seems more efficient (in terms of "used space" and ressources).
Ah well let's see how the supposed and so called "octacore" will score in the future...
processor differences
okay I know both processor are snapdragon 600's but why is the galaxy S4's processor clocked at 1.9 ghz and the HTC One's processor is clocked at 1.7 ghz is it just an instance of samsung overclocking the s600 or are they different variations of the same processor, I have done some research and am able to find no clear answer to this question even on the snapdragon website????????

They should be identical. I think its just a manufacturer choice. But it could also be associated to termals or battery.
Cause Samsung took the higher frequency chips, there is the possibility that they also get the "better" chips: Lower Voltage for the same frequency. But thats just an assumption.
Is this dual core really comparable to the quad core processors available? I just got my N10 and I also have an HTC one phone and the phone is blazing fast in my comparison to the nexus. Also I'm concerned with will this processor move forward along with the updates a nexus device gets in it's life time? I think 4 or so android updates is common with a nexus device? Thanks to those who may give an honest opinion rather than new biased to a certain product.

Most cpu tests favor the nexus 10 over the HTC.
Gpu tests appear evenly matched slightly favoring the htc. (easily overclocking the gpu with custom kernels should fix that.)

It depends on how the benchmarks are weighted for single core vs multi-core processes.I believe Antutu heavily tests multi-core processes.
Other benchmarks take a balanced approach such as geekbench. If you look at the link above, the Geekbench total scores of the nexus 10 and htc one are actually really close with a slight favor for the snapdragon 600.
If you look at the single core process subscores, the nexus 10 wins.
If you look at the multi-core process subscores, the snapdragon wins. (makes sense: 2 core processor vs 4 core processor).
Because in the real world, a majority of apps are still designed as single core processes, Geekbench will test and weight single and multicore processes fairly equally in calculating total scores.

The Exynos 5 Dual in your Nexus 10 is a Cortex A15, the most powerful type of ARM chip, which is in only a handful of mobile devices so far. The HTC One, by comparison, has a Krait, a souped-up version of the Cortex A9, the older ARM chip that is in most mobile devices. For raw power, they're probably comparable, even though one is dual-core and the other is quad-core, with the Exynos edging out the Snapdragon in those web browsing benchmarks that freshlysqueezed linked to, while the Adreno in the Snapdragon edges out the Mali in many of the GPU tests.
The big difference is probably battery life, as the Nexus 10 can suck 5-10 W max (though 3-4 W of that is probably the huge display), while the HTC One pulls 4 W max. That's why everybody is going with Snapdragon for the current lineup of phones, the combination of high speed and minimal power can't be beat. Even Samsung, who wanted to put its Exynos 5 Octa, with a quad-core Cortex A15, in the Galaxy S4, has admitted to putting Snapdragon in most of the S4s, though that might be related to fabrication problems they're having with the Octa.
One reason the HTC One might seem "blazing fast" when compared to the Nexus 10 is that the Nexus 10 screen has twice as many pixels as the HTC One's display, though I doubt you'd notice any lag. I don't think the Nexus 10 will have any problems getting updates, as it's the first Android device with Cortex A15 and all high-end Android devices will be getting Cortex A15 over the next couple years. So the Nexus 10 is already ahead of the game.
The one big miss with the Exynos 5 Dual in the Nexus 10 is that it doesn't have a low-power core for light usage, what ARM calls big.LITTLE. That's what the Exynos 5 Octa uses, a quad-core Cortex A15 is the big component and a quad-core Cortex A7 is the little. That way, you can switch back and forth depending on how heavily you are using the device, saving power when you're not using it much. ARM is pushing this in a big way and even though not many chips have it yet, if it becomes common, the Exynos 5 Dual will be behind. Of course, Android will still always support non-big.LITTLE chips, you just won't get the benefits of big.LITTLE. A little chip would have been particularly useful given the high power draw of the big chips in the Nexus 10.

Four or so updates is a lot for Android; I don't think you'll really find a phone other than a certain HTC phone (hint, it started with Windows Mobile) that'll get more than that. Keep in mind that even the lowly single-core Nexus S got its update to Jelly Bean-- I also have the Nexus 10 and HTC One, and both have the horsepower to stay in the game for quite some time. As a Galaxy Nexus user as well, I can also say that even relatively underpowered devices can stay kicking for some time.

Is there a better tablet or there than the N7? Right now. The screen resolution should be superior to all other tablets but next to an iPad with the same game playing this isn't as good. My girlfriend proved that. She likes i anything. I'm an android guy. Is the gpu not so good in this device? I like it don't get me wrong. But I just bought it and if there's ifs something better I would rather have the latest and greatest. I really do not understand why this isn't powered by a quad-core. I feel like my son's nexus 7 had better graphics. At least when I look at his screen it just looks better to my eye.

This dual core/quad core thing is a red herring, sorry. The Nexus 10 went with a dual core A15 because the performance boost provided by an A15 was such that Samsung could afford to use a dual core chipset (meaning reduced power consumption, both due to reduced core count and improved architecture) while still blowing out all comparable chipsets at time of launch. The Tegra 4s (if they're not hobbled by memory bandwith issues like the Tegra 3s) will be a half/full generation ahead of the Exynus 5250 when they launch, so you could sit and wait for those (they also have pretty good GPUs).
The Nexus 10 has a powerful GPU, but some of it gets sapped by driving the enormous screen resolution. As far as the screen goes, it's an amazing 10" IPS panel without too much else to say. The Nexus 7 has a WVGA 1280x800 IPS panel with significantly lower PPI, and you generally hold a 7" tablet a bit closer, which can compound the density drop. However, on a 7" device, it's hardly bad.
The Nexus 10 is going to beat the crap out of the Nexus 7, but if you want to switch, I'd wait for the next Nexus 7 (which is rumored to have an upgraded screen and proc in a similar price envelope as the original), or for the first Tegra 4s. There's not really much else on the market that'll beat a Nexus 10 right now in tablet-land.

Just a quick reply to point some things out. The Snapdragon 600 in the One is a quad-core A15 with Krait 300 architecture. The 600 is about as powerful as the 5250 with better multi-threading. Also most chipsets currently use A15. It is the current standard, not something that will "happen over time". The CPU has nothing to do with the screen res, the image processing is done through the GPU. And finally, I expect the 5250 to be eclipsed relatively soon, as chipsets supporting higher clock frequencies(like the 800, or even the rumored Tegra5/6 with a possible 3.0Ghz clock) start to enter manufacturing. Sorry for the brevity, I'll edit this a bit later when I get more time.

Tegra 5/6 is purely theoretical at this point. It's also best for clarity to note that most new chipsets are switching to A15 (or customized variants thereof). Most chipsets in the market right now are A9 or lower, and there are still phones being released running high-end A9 kit. The CPU also does have some role to play in screen drawing, especially for handling elements that are not using GPU rendering for one reason or another. This interaction isn't as significant as some would believe, but it cannot be discounted entirely either.
The Snapdragon 600 is probably on par with the Exynos 5250, that much is definitely true. They're pretty neck and neck and will outclass one another on different aspects of CPU performance, but both are quite good.

Plus the rumor is that Android 5.0 is being heavily optimized so it can run even on older phones, even with 512 MBs of RAM. If true, they may keep current devices updated for a while, as it may take a while for Android to bloat up again. :highfive:

lol @ the "up again." Hopefully they keep moving in this direction, towards leaner, sleeker software. And one of the nice kicks about modern, flat, industrial design is that it doesn't hit system resources quite as hard.

As Rirere says, Koopa777's post is pretty much all wrong. Krait is not Cortex A15, it is a unique design from Qualcomm that is somewhere between Cortex A9 and A15, which are off-the-shelf designs from ARM. Most current chipsets are Cortex A9, not A15. The Exynos 5250 Dual will of course be eclipsed with time, for example, the Tegra 4 will be coming out later this year with a quad-core Cortex A15, but right now the 5250 is basically the only Cortex A15 chip, other than the aforementioned Octa, which just came out.
As for Tegra 5/6, those won't come out till next year, I don't think anyone is planning on waiting till then.

Got to say, I'm looking forward to the next generation. I upgraded from a Galaxy Nexus (TI OMAP 4430) to the Snapdragon 600, and it was like night and day (the Nexus was my first smartphone, although I'd played around with many Android devices before). Amazing what processor tech is like these days.

Eh, if it's using twice as much power to get these results, who cares? Let's see how the battery life is.
I picked up a HTC One X+ with the fastest Tegra 3 and it gets very hot when playing 1080p video, burning battery like crazy. Even the Exynos 5 Dual in my Nexus 10 runs pretty hot when playing 1080p video. All these processors are powerful enough these days, whether they'll kill your battery or not is the real test.

Hot can be a sign of bad heat flow though, more than power consumption. A15s are better than A9s in some efficiency regards, but pumping them up to a higher clock speed will eat through that saving.

Thanks to the awesome DEVS here at xda for the great flexibility in our kernels. Great battery life when you need it and speed at other times.
Agreed, thermal regulation and throttling is an issue, but Qualcomm seems to be doing pretty well with these issues as well as battery life in my HTC evo 4g lte and my sisters galaxy s4.
We will have to see for the new 800 and tegra 4.
