Question about the Tegra 3 processor in Nexus 7 - Nexus 7 Q&A, Help & Troubleshooting

From what I read, Tegra 3 has three modes:
- Performance
- Balance
- Power saving
http://www.tomshardware.com/reviews/transformer-pad-tf300t-tegra-3-benchmark-review,3179-2.html
In other ASUS Tegra 3 Android tablets, user can select and set the mode.
Is it also possible with the Nexus 7?
If not, which mode is set by default?
Thanks.

Well, as far as I know this has nothing to do with Asus tablets. The Asus tablets are running costum UI from Asus and these are just kind of "tweaked mods" from Asus integrated into their UI. That on the other hand has nothing to do with the Tegra 3. The only possibility to set your own "CPU mods" is to unlock, root and get a costum rom running on your devices with the ability to govern everything about CPU.
@your last question, there's nothing more to be said.

Tegra 2 forgotten?

has game developers forgotten about tegra 2 and just moved onto tegra 3 i mean i see alot of awesome games coming out such as Horn or the new game coming out Wild blood which is supposed to boast the unreal engine or even bladeslinger but all run on tegra 3 , i mean if i can run Dead trigger highest graphics under clocked with no lag then why move on? even Max Payne mobile highest graphics and under clocked runs fine. is it just devs wanting to work on tegra 3 for the consumer market in it or is tegra 2 just that old?
Yeah it doesn't make sense I'm sure these high end apps could have somethings set up just to scale down settings depending on hardware of the device. Kinda like PC games do which will try to match the best settings for the hardware (which usually is OK)

yeah i guess its just time to upgrade :/ im going with an actual cmputer tab 320 gig harddrive 2.2ghz win7 winpad i think unless i can find a better one i can use for work :/
Maybe all those Tegra 3 only titles are sponsored by Nvidia and Nvidia wants them to be T3 exclusive to attract more tablet/phone buyers. But they showed with Tegra 2 how much they care about the hardware they already sold (we are not even clients to them as we ONLY buy end products with Nvidia hardware).
I think the same will happen when Nvidia presents T3 successor in the future. All THD titles will be made for this next chip and T3 will be forgotten as T2 is now.
I think that developers' decision to support T3 exclusivelly in their titles is Nvidia's doing because developers are actually shrinking their potential customer base (how many T2 tab users is out there comparing to T3 user base). WIthout money from Nv I don't think any developer would do that unless they need so much processing power that T2 is not capable of delivering any more. And @gears177 gave 2 examples that T2 is still capable of running good 3d games even underclocked. T3 is just overkill for most titles.

Nexus 7 tech specs query from buyer

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.

1. Its either dual or quad I think clocked at 450 or something(can be over clocked)
2. Underclocked I think(prime has same CPU but at 1.5)
3. Don't know
4. There's a few apps that do this
5. No you have to sideload
6. Stereo and don't know about surround sound

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.

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.

Which is the better device? Nexus 7 or Nexus 10?

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?

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.

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 say wait another 3 months before committed to buying 10 inch. Google might upgrade its 10 inch with 3G, who knows, having experiencing what they did with 7 inch.

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 .

Can Tegra 2 overclock to perform like and be recognized as Tegra 3

Sorry if this has been brought up before. Tried searching and did not find much. I love my Transformer tablet but hate all the love being given to the new Tegra 3 tablets and Nvidia releasing Tegra 3 only titles and such. I read that you can edit some games to show extended graphics in some games but are there any kernals out there and overclocking procedures that can get the original transformer tablet performing like a tegra 3 tablet and play all the tegra 3 only games? I have had my transformer for a while and have tried to refrain from rooting it and doing custom roms but I think I want to root and rom it and help it to start performing better. Any suggestions on if and how this can be done?

You can root and install custom ROMs and get perhaps better Tegra 2 performance, but you won't necessarily get the same level of performance as Tegra 3. Tegra 2 only has 2 CPU cores where Tegra 3 has 4 active + 1 slave core. You would have to have software that reported the CPU as Tegra 3 to fool other programs, but you still wouldn't have Tegra 3 graphics no matter what you do.
To OC the transformer you need an over clocking kernel. Most custom roms have a decent OC kernel.
I like setcpu as my OC app. You need to be rooted for this app to work.
I don't know if you can get Tegra 3 performance or anything like it but I know it runs Dead Trigger quite well with extended graphics enabled.

Changing my P3110 TAB 2

Hi,
I have a TAB 2 P3110, i ask my self is it worth to buy the TAB 3 SM-210?
My question is in the performance level.
Thanks for your opinion.
A friends son has the tab3(7") and have to say it's not as good in my opinion...
we have played the same games together and the graphics on his are really bad (eg f-18 game) I have graphics up at highest with out issues yet he can't do the same as its jerky and there's a sort box always showing up where the game area is and same with x-plane....
I also discovered he can change his tab 3 via a a bog standard cigarette usb charger where as I can!!! and battery on the tab 2 seems to out last his tab 3(which is only 1month older than my tab 2) by a good 3 hours and the list goes on....
Personally I think the Tab 3 for what you get is not worth the upgrade and just do the compare check at gsmarena.com and you will actually see there's not much difference other than tab 2 has a gpu(could ot find ref for on on tab 3)
just my opinion
regards

Thanks for your opinion.
What about the difference between the TFT screen in the TAB 3 and the PCS LCD in the TAB 2? Is there a big difference?
And the 1.2 Dual core is not faster than the 1 dual core in the TAB 2?

you can over clock the tab 2 just as I have done and besides its from what I have read the same processor any way..
screen wise honest didn't see any difference...

Tab 2 can be over clocked and is supported by a good no of developers due to the openness of to omap platform . if you want a real upgrade then go for nexus 7 2013 ,it's worth more than u pay for it?
