If Nexus S (2?) has similar hardware to Galaxy S, is it easy to port 2.3?

Even though I have followed dev/porting for 8 months starting with HTC Touch, I have little knowledge of how it is actually done. So here's my question to the developers.
We all know that Nexus S (2?) will have Gingerbread 2.3. Looking at the rumored specs and model number, it seems that Nexus S is a slight upgrade from Galaxy S.
Assuming most of the hardware is identical to Galaxy S, how easy is it to port 2.3 to Epic 4G, once Galaxy S becomes available?
Specifically, what is needed to bake a new 2.3 rom? Do you need to reverse engineer like what devs did on HTC WM devices? Or is it a straight port? I suspect it's somewhere in between but want to hear from you.
(If necessary, please move this to android development forum.)

The simple answer to this (which has been answered in other threads already if you looked) is no its won't be easy.

Also, the Nexus S is rumored and pretty much guaranteed to launch with a dual core processor. The rumor is that they delayed the device and gingerbread to implement this, since it will be google's new flagship device and has to be cutting edge. Everyone knows that dual core processors are set to hit the market within the first couple months of 2011 anyway, so releasing an old generation processor in a flagship google phone just makes no sense.
So no, it will not be easy to port from the Nexus S. It will not only have a completely different processor, but will also probably only be a GSM phone.

I agree and think this is the bigger problem (for the Epic at least).
Sure would be nice if the folks at Google would release at one clean Google device for each carrier. I'd be on it in a heart beat.

Yes that would be nice if they did that.I am surprised they are even doing another google phone by the way it sounded when they stopped marketing the nexus 1 that had no interest in doing another google branded phone.

Those are just rumors, all of the official specs that have come out say it will be a 1.2ghz hummingbird. The dual core 1ghz orion chip is definitely on the horizon but I highly doubt they will be able to get it in at the last minute, and there's a good chance we won't see it in phones until late next year. All rumors of a dual core Nexus S have had no credibility with their sources.
That said, if this turns out to be a dual core phone and gingerbread turns out to be optimized for dual cores, a port will probably be very difficult. But if it's just a 1.2ghz hummingbird then it would just be a matter of getting the CDMA radio working.

The reason that I think he has to have a dual core in it is as follows:
If it has a 1.2 ghz hummingbird processor, BFD. It immediately launches and is mediocre. Nothing exciting at all about it.
If it launches as the first dual core phone, it is the top of the line phone worthy of being branded as a Google flagship device.
Also, if it just had a 1.2 ghz hummingbird processor, what is the holdup? It is no different from phones released months ago. Also, if its a 1.2 Ghz processor, it will be eclipsed within a matter of a month or two performance wise by Tegra 2 and dual core snapdragon processors. Basically, it would be an embarassing flagship device. The original Nexus is still to this day a damn good phone that is near the top of the pack of android phones performance wise, and it is a year old.

You are fully aware the the Tegra 2 do not even exceed the hummingbird in gpu or cpu performance right? Im just saying cause it would suck if you didn't know what you're talking about.
Plus gingerbread will have HW acceleration, putting gpu performance on a step for the overall fluidity of the gui. So again... what's faster?

Really? I assumed it would greatly ourperform. Where did u get your facts.

I'm trying to find the article again, but i know they were close but Tegra 2 did not outperform the hummingbird. Apparently now they optimized the platform more.
Don't get me wrong i love nvidia, that's all i've purchased and stayed with them even thou they still dont have a decent dx11 card that doesnt need 2 power supplies. But they really need to step up and their CEO needs to wattch what he says and deliver more.
Here's a quote "On the 3D side, Nvidia says it has doubled the performance of the initial Tegra, resulting in a peak speed of 90 million triangles per second. This level is well beyond the performance of any mobile processor shipping or even sampling today." Hummingbird has the same exact performance. And CPU performance is a very interesting area. Anyway the GPU performance is almost par with the Hummingbird leading maybe by 3-5%

Since Tegra 2 is dual core and android does not have 2 core support till Gingerbread (Actually I don't think it even supports cortex A9 till gingerbread)..so if they ran 1 core vs 1 core I'd see a hummingbird win against a Tegra 2..but if Tegra 2 is running dual core (and optimized for it) it should win...but by that analogy Orion would then be superior.

Not to mention that Tegra 2 does 1080P video recording. So yes, releasing a google flagship phone that within one month is eclipsed by LG with the first Tegra 2 phone, would be embarrassing. The Nexus 1 set the standard for almost a year, before the Galaxy S line came out. If the Nexus 2 can only set the standard for under a month, that would be stupid. Therefore, it is easy to conclude that the rumors of the Nexus S having a dual core are most likely true. Doesn't mean it has to be the Orion, but it would be awesome if it was.

Tegra 2 is a Cortex A9 CPU... as is the Samsung Orion and the TI OMAP4xxx chips. They accomplish 2.5 instructions per MHz as opposed to the 2 instructions per MHz in the Cortex A8 Hummingbird, and that's not counting improvements to instruction efficiency (getting more done with less instructions.) Add to that improvements such as out of order instruction handling and dual-channel memory support and Cortex A9 chips are head and shoulders above Cortex A8.
The only reason Tegra 2 wouldn't outperform Hummingbird significantly is, as mentioned, lack of dual-core support in current builds of Android, and the nVidia GPU which is, surprisingly, only just about on par with Hummingbird's PowerVR SGX540.

I'm not sure that triangles per second is accurate to describe performance.

The Hummingbird has memory bandwidth limitations that I don't think the Tegra 250 will. Lets wait and see.

Here's the facts dude, and try to get this; Tegra2 does not, in fact, suck. You just posted a video of it being benchmarked on a netbook running Android 2.1 which cannot make full use of Tegra2's dual-core CPU. Secondly, neocore is a GPU test, not a CPU test. We already discussed the fact that the Tegra2 GPU is only just about on par with the SGX540. Thirdly, that test is being run at a signifcantly higher resolution than a mobile device would run, and frankly, considering this, the score isn't bad.
Fail, man, fail.

I would also like to point out that I wrote the article that sauron0101 just linked. It's also posted on my blog (linked in my signature) posted back in March. Tegra2 does feature dual-channel memory support as part of the Cortex A9 architecture, which is a significant advantage.

Any idea how fast the other Arm Cortex A9s are compared to the 250?
- We know that the SGX540 will be in the TI OMAP 4 series; probably not bandwidth limited - I am surprised that they did not opt for the SGX545
- The Samsung Orion series has Mail 400 (unknown performance)
- The Snapdragon (A8 unless Qualcomm opts to keep the name "Snapdragon for its A9 CPUs) will have a new generation of Adreno 300 graphics
Unknown if we will see this on mobile
- Marvell also has a new SOC
Also interesting is Samsung's Netbook roadmap, which uses the same SOCs on a phone:
Sorry if all of this is a bit off topic, but it is worth looking at what everyone has.
Edit: Qualcomm is keeping the Snapdragon name for the A9 processors.

Does no one see i was talking about Gpu perfomance? That's what's gonna matter in Gingerbread. And that's running 1024x600 on that res Galaxy tab is around 53 fps. It's the same thing that Vista started doing with HW accel so u understand.

geforce ULP vs Adreno 220 vs PowerVR 543

This post is not to start a flaming war against any of the devices using any of these chips.
I just wanted to start this post for information.
Im a bit concerned with the geforce ULP which shows only around 20-30% increase over the previous PowerVR 540 chip.
The PowerVR 543 is supposed to be a multicore version that is much faster than the PowerVR 540 (Also, the PowerVR543 dual core is rumored to be in the ipad 2)
Additionally, the new adreno 220 has been showing off its tech and is rumored to be in the new dual core qualcomm chips.
The problem i see is, that while the dual core CPUs seem to be equally matched in terms of A5 vs tegra 2 vs dual core qualcomm, the geforce ULP seems to be heavily outclassed by the powerVR 543 (perhaps even the single core) and the adreno 220.
Does this worry anyone?
I know that the games coming out for the tegra 2 are looking quite amazing, but at the same time people are saying no low framerates, and when I looked at dungeon defenders HD in the store, the framerates, while playable, where not that high..
If the ipad 2 is going to have a dual core PowerVR SGx543 then it is going to crush the geforce ULP. And the adreno 220 looks to be a high performer as well.
I feel apprehensive jumping into a technology (the tegra 2 with geforce ULP) that is already heavily outclassed by its competition (ipad 2's A5 with power VR 543)
I dont want to get into a competition between iOS and honeycomb - and I agree that it depends fully on how the developers utilize the chip - but with such a huge performance difference, I can see developers making more amazing games with the faster chips.

The Tegra 2 is fine for gaming. It can handle its own. Media playback is an entirely other issue and the Tegra 2 is a failure in that regard.
We haven't seen either the Adreno or the SGX543 benchmarked yet at all, so its too early to say they are better than the Tegra 2. Also, I feel as though Nvidia is going to be pushing for a lot of games to be made specifically for the Tegra 2. If that is the case its going to fragment the Android market even further.
Its not fair to look at the Xoom's benchmark due to the much higher resolution skewing results downwards, so lets look at current generation phones:

You can see the best performer right now is the old SGX540 clocked at 300mhz. I would bet that the SGX543 is a monster.

Judging by these articles - Tegra 2 is doing great.
Besides, nVidia is excellent when it comes to updating drivers on their GPUs and working with game devs to help them use the GPU's potential.
So, if they do the same for their ULPs, we should expect frequent Tegra 2 updates and great games coming.
Actually, even now, a mere week from release - check Tegra zone and see the amazing games that will be released this/next month. Mindblowing.

I agree NOW that it may be the fastest - but in one week when the ipad 2 comes out - it will supposedly do LESS THAN HALF of the ipad 2 graphics capability - thats a huge hit in performance.
THis means that the ipad 2 can handle a class of games far above what the tegra can. Its just unsettling is all.

The iPad 2 is not going to be 2x faster than the Tegra 2. The graphics processor it uses will handily beat the Tegra 2, but not by 100%. It really depends on how many cores the SGX543 has. Wikipedia says it can be anywhere from 2-16 cores.

i guess we will find out on march 11th
but if the SGX543 has 2 cores and each single core is faster than the tegra 2 geforce ULP, then combined it will likely be 75-85% faster than the tegra 2 (i agree no more than double)
Having said that, that is still a huge upgrade.

well you kinda know the ooutcome without waiting...each sgx543 core outperforms a tegra2 by roughly 50% ..with 75% more fillrate,huge shaders e.t.c ..and since they went dual core on gpu, well..they should be around double in performance terms against xoom,maybe more,given xoom is running on higher res..what IS surprising is that samsung made the chips for them but still on their own products chose the lesser exynos/t2..

Wasn't it pa semi and intrinsity that made the chips for apple? Samsung also works with intrinsity to design their soc.
I've read a rumor on I want to say anandtech, that the CPU cores of the ipad 2 may only be 1Ghz cortex A8 vs our dual A9s. That gives us a heafty lead in the computing department. Also just because a mobile gpu has the potential to be rediculously fast, doesn't meant it actually will be when used in the soc. It it depends on frequencies and bandwidths as well. For instance the TI omap4 uses the same gpu as galaxy s, vr540, but handily wins benchmarking due to its dual A9s and dual memory channels. And if you guys are worried about cores, we basically have 4 split into eight, so eat your heart out, dual core gpus!
The fight definitely ain't over yet fellas! Have some faith in nVidia!

I'm not very sure about the architecture of mobile GPUs, but if it is in any way similar to those of desktop GPUs then the number of cores and the core speeds matter only upto to a certain extent. If you look at AMD GPUs, they are filled with a lot of cores (~ 800 is common) running at pretty good speeds, while the equivalent NVidia GPUs have about quarter or even less cores (~200 is common with the newer fermi cards having more cores) at usually lower speeds . But NVidia makes up the performance with its memory bandwidth. The end result -- both GPUs have a similar performance. My guess is it would be the same with these mobile GPUs. Just my 2c.

Actually they have and it blew XOOM out the water I mean earth. PowerVR 543 is much better and that is why I am suprised that Nvidia didn't do enough for their GPU. I was also suprised that Samsung went with them instead of their accomplishment with the PowerVr

i sstill dont ththink those benchmarks are right because I don't thing the software was optimized for tergra2

I know this thread is ancient, but I just have to call all of you morons, especially you muyoso.
Not only is all of that wrong, but the benchmark used has glitches with the SGX 540, putting it at a disadvantage, also the galaxy s phones are framecapped.

Plp are saying the Nexus 7 processor is faster then then the 10. This true?

It's probably quite difficult to find a use case on a tablet where more than two cores provides any tangible performance increase, but the much higher clock rate and newer architecture should definitely make a difference.

Benchmarks shows that the new dual core is much faster than the n7 quad. Also the 2gb of ram

I suspect it's mostly because "Plp" don't understand how 2 cores can be faster than 4 cores.
Yes, they can and yes, they are. ARM15 CPUs have a new and vastly superior architecture.

It's top notch. Although core counts are great for marketing, don't get to worried. After people get their hands on it, we will have a better idea of performance. I remain confident I'm about to purchase the most powerful tablet available.

Technically that's not true, the latest iPad, I believe, vastly out performs this thing. That said, how is it gonna make use of all that power other than playing games, which let's face it, that's all iPad buyers do really...
Not like it'll be cracking aircrack dumps eh.

I saw a benchmark that placed the nexus 10 under the transformer TF300 (antutu). Would this be accurate? I would've thought that the nexus10 would've outperformed the transformer which has a quad core tegra 3 processor.

4 * 1.2 GHz = 4.8 GHz

Clearly, the Nexus 7 is much faster.
That is the discussion level when people come to the conclusion stated in the topic. Even in benchmarks - which all of the reviewers agree don't mirror the level of performance they experience in real world use - the Nexus 10 comes out way higher than the Nexus 7 while pushing 4 times the pixels! The Nexus 10 runs circles around its little brother...

The differences are so vast, it is almost incomprehensible to some. I'll use my same reference as I do with desktop processors. When quad cores really started coming around and making big appearances; software and games weren't exactly capable of utilizing the abilities. So, an e8400 3.0GHz dual core would out perform it's bigger quad core brother that ran at the same frequency and architecture in a lot of applications. Back in 2008, gaming rigs almost always would sport the dual core processors. Simple fact is that those processors use cache that is on the die. 6mb for two cores is better than 8mb for four cores.
So, until software developers really have a need for a quad core, the dual cores will run with the quad cores just fine. Benchmarking however, almost never show any real world performance. I'm sure this dual core is going to surprise even the more skeptical guys and gals.

The benchmarks are selling the N10 very, very short. There is a great review linked in this post where the author says exactly that.

Here's the post that stamps its feet and declares the absolute truth:
Cores aren't everything.
And you can think that we're just a bunch of fanboys trying to justify the use of dual core in the Nexus 10, but even non-fanboys who know how these processors work would tell you a dual core A15 is far more powerful than a quad core A9.
Now everything below this post is purely observation based (I'm not an engineer nor have I really studied up on computer parts), but I think it gives a casual user a good idea of how a CPU works.
So, before you go out screaming "wtf. why are there only 2 cores in the nexus 10. lol so noob," ask yourself this: what do extra cores even do? If you can't answer that, then don't complain because you clearly don't know what you're talking about. It's not simple multiplication of the frequency (for example, 4 x 1.2ghz = 4.8ghz). A 4.8ghz phone would be able to run Crysis without a problem (of course with a dedicated GPU, but that's besides the point). That's obviously not the case.
The major difference between the A15 and the A9 is their microarchitecture. You can think of it this way. A mouse has to go through a course. There are two courses:

}
and
.
We call the maze A9 and we call the straight route A15.
Now, we will pretend "ghz" is a measure of intelligence (higher the better). A mouse that has an intuition level of 2.0ghz has to go through maze A9. Complicated right? It'd take awhile even if the mouse was kinda smart. But now a mouse that has an intuition level of 1.7 ghz has to go through maze A15. Easy. The maze route is a straight line - who wouldn't be able to find the end? So in the end, we ask ourselves, "Who gets the job done faster?" Obviously, the mouse in the A15 does even though it's not as smart. In this way, the A15 is just more efficient. So clock speeds (which are things like 1.0 ghz, 2.0 ghz, 1.5 ghz, 1.8 ghz) are only a part of the story. You need to factor in the microarchitecture (or in this example, the way the maze is organized).
Now, we go into cores. We can think of cores as splitting the work. Now, we will consider this scenario: we want to calculate how much time it takes for the maze to be completed four times (regardless of how many mice you are using - we just want to complete this maze 4x). A quadcore CPU that contains the 2.0ghz mouse can be represented by 4 mazes:
The dualcore CPU that contains the 1.7 ghz mouse can be represented by 2 mazes.
.
With the quadcore CPU, we will finish the task in only one go. Just put a mouse in each maze, and once they're done, we've completed the maze four times. With the dualcore CPU, we will finish the task in two go's. The mouse in each maze will have to go through each maze twice to finish the maze 4x. However, let's look at the "microarchitecture," or the maze route. Even though the dual core CPU (A15) needs to finish this task in two go's, it'll still do it a lot faster, because the route is far easier to go through. This makes the A15 more powerful. You can complete tasks quickly.
So when judging the "power" of SOCs, you need to keep three things in mind: cores, clock speed, and microarchitecture.
Clock speed = frequency such as 1.5ghz
Cores = dual core, quad core
Microarchitecture = A9, A15
Sometimes the microarchitecture won't be a vast enough improvement to justify a seriously lopsided clock speed. For example, a 4.5 ghz Intel Sandy Bridge CPU will be tons faster than a 3.2 ghz Intel Ivy Bridge CPU even though the Ivy Bridge CPU has a new microarchitecture. But, an Intel Sandy Bridge CPU clocked at 4.5 ghz will be slower than an Ivy Bridge CPU clocked at 4.4 ghz because the microarchitecture is slightly better.
Anyway, I hope this clears things up. I know the information here is probably not 100% accurate, but I'm hoping this is easier to understand than pure numbers and technical talk.

Where are the idiots that keep saying this? Honestly, I'm growing tired
Think about it, do you really think the quad core in your tablet is faster than say, a dual core core i5 in a laptop?
NO
Maybe this explains to you how a new processor architecture (A15), even at a dual core, can be faster than a quad core on the old architecture

Good explanation @404 !

What I'm worried about is whether the processor can handle that screen. I wonder if its possible to overclock it?

Samsung announces Exynos 5 Octa, an A15 and A7 hybrid SoC

Samsung's most exiting announcement yet - the Exynos 5 Octa chipset.:laugh:
It brings 8 processor cores, which distribute the work load among each other.
Four Cortex-A15 cores ensure incredible performance while the other four are low-power Cortex-A7s that kick in for the less demanding tasks and save battery power.
The chipset is based on ARM's big.LITTLE tech, which ensures that you will always get enough performance without having to deal with terrible battery life.
Samsung promises up to 70% lower power consumption compared to the Exynos 5 Dual, which is powering the Google Nexus 10 tablet and the latest Chromebook by Samsung.
The Exynos 5 Octa could posses as much as twice the 3D rendering prowess of the Exynos 4 Quad, which is found in the Galaxy S III. :good:
Will this end to Samsung S4?

Hard to say, normally use exynos 5 quad since no device using it yet
Yet, the other 4 core should use cortex a9
Then totally is a beast already

So? What is it that a single A15 core can not do but 4 A7 cores can? Low expected performance or low power consumption?

I think the main idea about this chip is the low power consumption.
Tegra used single companion core but Samsung uses 4 companion core-like.
Samsung is crazy they may add it in S4, besides they are the manufactures.

I understand the swapping on the fly between the lower and higher cores, but the heat question is not answered for me. Can somebody with better knowledge enlighten me?

Some rumours suggest that they'll use the 8 core in tablets and chrome books, and that the S4 may have a 4 core version with 2 A15's and 2 A7's. Just a rumour but heat and volts will be a lot lower with 4 less cores. I have no idea how dual A15's are in terms of perfomance, haven't checked other phones benchmarks in ages

You must look at this as the current Intel laptops who have I3,5,7 processors.
When you are browsing the web the onboard videpchip is doing all the rendering. But when you Start up for example FarCry the onboard chip gets overloaded and the graphics card takes over the duty. Power when you need it, to save power.
Another example :
When the V-TEC kicks in yo !

The reason for the A15 and A7 is that the A7 will handle simple tasks and minimal multitasking but when pressure is placed on the CPU it will switch to the A15 to easily handle it then back to A7 when the power of the A15 is not needed aka BIG little tech which means the perfect balance between performance and battery life

If they switch to Dual A15 and Dual A7's then Sony Z will take over in performance and will be the number one choice.
If S4 gonna have Big Small 8core its gonna Rock and will have unbeatable performance.
About the temp, when on 3G and browsing i guess it will be on A7 so temperatures is expected to be low.
Do you know most of the time S3 uses dual core and the rest are off and sometimes single core only!!

Note III will have plenty of space to include this monster of a chip. Looking at all the 5"+ devices at CES, the S IV will also be big enough for it (and also with enough room to dissipate all the heat).

Guys, just think, if you check on wikipedia, there is no Exynos 5 quad and I don’t think they will release any after the OCTA: http://en.wikipedia.org/wiki/Exynos_(system_on_chip)
As everywhere is said, the exynos 5 quad will be just a murder for a battery, so I’m sure they will use OCTA in S4. Come on Samsung, we want S4 with OCTA !

Anyway, those slides are great. It supports all use-case models so basically the possibilities are limitless on the side of the kernel and power management. Only thing I wonder now is if the two clusters are on separate frequency planes.

N 10 processor

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.

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.

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.

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.

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.

Yeah. I agree. Even the older quad cores once a device has root.

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.

That's why I underclock/undervolt when I play my mkv movies.
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.
