any reason for the 1.15ghz CPU speed and 400(ish)MHz gpu speed other than cost? or do you think they underclocked to save the battery? hoping we can over clock to t30l speeds

No need to worry. developers will get this tablet to at least 1.5ghz or more. overclck tweaks for transformer prime should work on this also. all it'll need is root
Do we really need to overclock this? I mean I probably will anyways but a 1.3 Quad is pretty zippy by itself!
As the tegra 3's gpu compared to say the galaxy s3 (international) is fairly weak, I only hope we can OC the GPU by enough to make a difference. I am not that bothered to about OCing the cpu but I do care about the GPU

The Tegra 3 used in the Nexus 7 is a version of the Tegra 3 chip that didn't work within guidelines at the regular speeds, but were within guidelines for a lower speed. This is done regularly in Intel/AMD CPUs as well. That's why there are different speed CPUs in the same model family. This way they can sell the high speed CPUs at a higher cost and still make money off the CPUs that can't run as fast. Eventually the process to make the chips will be so efficient that they will artificially lower the speeds to sell as the cheaper version and that's when you can overclock like crazy and not have instability (if the CPU product cycle lasts that long).

This suggests Nexus 7 probably won't OC so well. Which wouldn't surprise or disappoint me. It appears Asus dropped a lot of little features to keep cost down(which I think is a good move), and using CPU s that didn't bin well is one good way to keep cost low.

Is this not enough for you? We are still in 2010...
Team Whiskey has put out a Vibrant kernel (alpha) than can hit 1.6Ghz, and they're working on 1.8 and 2.0. Once they release the code (which should be soon), it shouldn't take long for an Epic version to surface.
Is stability not a problem with these high overclocks? I don't understand how someone can just put out a Xghz kernel for everyone to use. Aren't there hardware limits, ones that will be arbitrary device to device?

Not unlike desktop CPU overclocking then.
Well yes and no...every one can be overclocked...it boils down to how much..and how well of an over-clocker a chip is..then obviously it boils down to manufacture quality aka luck of the draw.
For example...the 1st gen snapdragon is a sub par overclocker...while the 550mhz chip in the original droid is an awesome overclocker....
It kinda boils down to the manufacturer limiting the frequency to a certain amount..sometimes for stability..but often times to charge you extra for more mhz...Intel has been doing it for years selling the same chip in 3 different clocks when in reality it is exactly the same chip.
I mean if samsung wanted to they could have easily released it at 1.3ghz..they just had no reason to...
just wait till the Epic is running 2.2 and u will see who the real winner is
the biggest issues for smartphone ocing are heat n battery, cuz unlike a desktop were u can keep uping the volts n if it gets to hot just add more cooling, a smartphone is all passive so you cant go much above stock voltage or it'll melt, plus wht good is 2ghz if u can only run it for an hour b4 ur battery dies
So then why is it such a big deal to make a ROM capable of a high clock? Someone could make a 5ghz ROM, but it would never work. If Hummingbird CAN go to 1.8ghz, I don't see why the current overclocked kernel's don't already reflect that.
In other words, I think we shouldn't hope for much over 1.2ghz, which is already pretty good.
Any stability testing programs for Android? Or is everyone saying "no crash = must be stable"?
The folks at the HTC Sensation/EVO 3D section extracted the Adreno 225 drivers from the HTC One S, as some of you may know that the Adreno 225 is the same as the Adreno 220 GPU but just have double the frequency! the frequency has nothing to do here if you ask, using these drivers gave them a HUGE performance boost with the STOCK frequency
as we know that the Mali 400 GPU at the SGSIII is clocked at 400mhz but even if you clocked your Mali 400 GPU in your Note (which has the same Resolution) you wont be able to reach that performance which tells me that its all about the drivers just like the Adreno 225
So can the Developers extract the Mali 400 Drivers from the SGSIII so we can use it on our phones?
This is not a question so i think it belongs to here not the Q/A section as its just a discussion if this is going to work or not!
Same driver, bigger screen = performance loss.
That is why Sammy set CPU 200 Mhz faster on Note over S2.
Screen has NOTHING to do with anything the Resolution does, which is the same in the SGSIII and the Note
Also that's why i said if you overclock the GPU to 400mhz you still wont reach that performance so it has to do with the Drivers
The note and SGSIII do indeed have different different screen resolutions, the Note being at 1280x800, while the SGSIII is at 1280x720. not much of a difference though, basically 16:10 vs 16:9, respectively. I believe the new Mali400 Drivers will be in the next ROM update anyway.

if this really happened and it does work, what about the battery-life... can be poorer i think
In theory, I see where you're going with this, and in theory it sounds plausible. However, something that I think has been overlooked is the process design of the new S3's chipset vs the ones found in the current generation S2/Note (45nm vs 32nm). It's entirely possible that the only reason why Samsung is able to run the Mali-400 at 400mhz is due to the fact that the 32nm process is just that much more efficient, such that you can safely run at 400mhz using the same power as you would running at 266mhz on the 45nm process.
I just get the feeling that trying to push the 45nm process up to 400mhz might simply melt the silicon (or at least gobble your battery life in one gulp!). Call me defeatist if you have to, but I remain skeptical until I see evidence to the contrary.
I run my galaxy nexus with the GPU clocked to 512mhz (standard is 308mhz), and that cpu too uses the 45nm process.
Been running it like that for the last 3 months with no issue, and game fps is greatly improved.
Is there any kernels at all that even support over clocking the GNote gpu?
Very interesting, Would like to see this being investigated further for sure!
screen has nothing to do with it...on note we got 100k more pixels 1280x800-1280x720=100k

After some digging I found that the GPU In Exinos 4210(SGS2/Note) and 4412 (SGS3) is absolutely the same Mali 400MP4 (same number of GPU cores)! The only difference is that the 4412 GPU Can Go up to 400MHz (which is doable to our GPU too and have been done to the SGS2 already). The main difference here are the four CPU cores that help the GPU. I'm skeptical that the new drivers will do much (if at all) in terms of performance! Oh and lets not forget that the Adreno GPU Drivers are written by Qualcomm and they can't do anything right so the updated drivers may just be better written (or at least less buggier) than the old ones!

Note: battery drain is not a problem!!! I will use the nexus 7 for gaming most of the time and also browsing!!!
Please I really want to know i created an account on this site for this!!!
Most people can go to 1600 on the CPU. Any real world performance increase from the stock 1300 is negligible.
I wouldn't overclock the GPU past 446 (+30) because anything higher creates a lot of heat and people have reported benchmarks actually being lower once you go much higher than that.

Hi, tbh you'll probably not notice much if you overclock the cpu to 1.6ghz as percentage wise it isn't a large jump. Things may feel a little zippy at times though, in my house I have acces to two n7's, one stock and one overclockable to 1.6ghz. Ran tests between them and the 1.6ghz was fractionally faster, the difference was very small. Overclocking the gpu to 600mhz vs 416mhz at stock made a huge difference, as it it made some games actually playable. Despite the crap Nivida spit out about the tega 3 soc, it's GPU is comparatively weak. Over-clocking the GPU will give immediate performance increase in a lot of games. After doing heat and clock speed tests myself, I've found anything in-between 416-600mhz to give near enough liner performance increase and heat to be long term sustainable depending on the voltages your device can handle. Overall, I doubt CPU overclocking will give you much benifit, but if you play games the gpu overclock will. If your worried about heat from overclocking the gpu a lot, you can always use this kernel http://forum.xda-developers.com/showthread.php?t=1937146, which gives you full GPU clock and voltage control so you can undervolt your gpu to reduce heat. I wouldn't run at 600mhz unless I could undervolt the gpu as much as I have and I use that kernel because of it. I have my gpu overclocked to 600mhz running at 1225mV, which is only +25mV above stock voltage for 416mhz. Although most heat is generated from the transition period of the transistor charging/ discharging, undervoting does give a large positive effect on heat output if it's large enough. But 600mhz is a high GPU clock and the highest I'd recommend, tbh I would say 520mhz is a really good compromise between heat, performance and battery, especially if you under-volt the GPU at that frequency for most people if your not as annal with FPS as I am :silly:

The 2 GHz kernel was a test to see how far the Nexus 7 could be pushed. This kernel wasn't released for obvious reasons so yes, those pics/ benchmarks were true.
Post on Gsmarena:
"The motherboard has a Qualcomm Snapdragon S4 APQ8064-1AA chipset, which as it turns out is a downclocked Snapdragon 600 chipset – four Krait 300 cores (rather than Krait 200) at 1.5Ghz and Adreno 320. There are also four Elpida 512MB RAM chips, SK Hynix 16GB eMMC storage, a Wi-Fi a/b/g/b and BT4.0 capable Qualcomm chip and an Analogix SlimPort transmitter."
PS: Sorry if this piece of info was clarified somewhere else in the forums, I did not found it.

It's not exactly a 1.9GHz SD600 (APQ8064T, APQ8064AB) downclocked, but a Krait 300 variant (APQ8064-1AA) that is intended to run at 1.5GHz, so overclocking I'd imagine would come with plenty of throttling and battery consumption.
It really is the perfect HW for current generational need, it's not like we can do pro-grade stuff that needs Core i5 power, so it's best using the stock clock which is well balanced between performance and battery life.

I can't imagine overclocking to 1.7 would drain anymore than a percent or 2 of total battery consumption. With the current setup it looks like it can even be done with the same voltage settings to me.

Underclocking doesn't necessarily lead to a better battery life. It depends on the efficiency at the actual frequency. If you underclock, the chip needs less current but needs more time to finish the work load because it is slower. So what matters is total energy consumption: W = U * I * t (Voltage * Current * time). So to save energy, the current has to decrease more than the time increases for a given workload. Also we can see that decreasing the voltage (undervolting) also saves energy (in this case we don't loos calculation speed because the frequencies are untouched)
I know that the Note 3 got the Snapdragon 800 8974AA(GPU clocked at 450 MHz).

maybe its caused by throttling down due temperature
Maybe memory of Note 3 is faster and larger than other phone, which shouldn't be Samsung because S5 uses AC version. I think Note3 has very fast RAM and if other phone has slower (read cheaper) RAM it could bottleneck there. Also, as the other poster said the other phone could be thermally throttling, especially if the benchmarks were run multiple times to get average. You figure people running benchmarks would know better, but who knows.

The thing is that, other Note 3 get's around 9-10 FPS, which is normal for a 8974AA SoC. So either some Note 3's got the AB(which is unlikley) or Samsung is cheating again and overclocking the GPU to AB levels only for the Bench.

Samsung never overclocked anything, what they did in the past is ramp up frequency to maximum before benchmark started running, so there was no delay to get CPU/GPU to full speed, like you have with on demand governor. I don't believe it's cheating because you can set the governor to run full click yourself (if rooted) and benefit from this as well with any game/ benchmark. It also shows how inefficient ondemand governor is and maybe we should be using different governor setting which is interesting topic all by itself. I remember there was similar "scandal" few years ago in graphic card business, where drivers were optimized for particular benchmarks. Well, now all video drivers are optimized for specific, mostly graphic intensive games and we all benefit from it by having better performance, from lesser hardware. Maybe this could also benefit all of us by giving us better governors, so the phones can run faster with the same hardware, instead of being artificially slowed down with poor choice of governor settings. As far as other Notes running slower, thermal throttling due to multiple benchmark runs to get average would be my wild guess. Or maybe you deleted factory bloatware and change settings to make your phone faster, but no, you don't have AB version.
