Does anyone know if it will eventually be possible to overclock the GPU in the Nexus 5 to match the S800 MSM8974AB chip?
The S800 chip in the Nexus 5 is the MSM8974 chip which has the GPU clock of 450MHz, but there is another version of the S800 chip called the MSM8974AB which has the GPU clocked at 550MHz.
Here is a link for anyone that is interested in seeing all the differences between the MSM8974 and the MSM8974AB

It will definitely be possible with kernels. Don't know how safe it will be to overclock by 100mhz, but on my HTC One Elemental X gives the option to overclock from stock 400mhz to 550 (very bad for the device though). So the Nexus 5 will definitely be able to hit 550 as well.
Adreno 330 overclock 450MHz to 550MHz
Hello,
Is there any update about this?
I Overclocked the CPU to 2.5GHz via a custom kernel, but I am unable to pass the 450MHz of the CPU.
Please let me know if you have a solution.
Thanks
which device use MSM8974AB chip?
I have the Z1 also, which has the same chipset as the N5. There is a custom kernel for the z1 that OCs the GPU to 533mhz which I run stably with excellent battery life. So I'm sure it's possible to do the same with the N5 since it's the same processor. I'm sure one of the smart devs here can look at the github posted here: http://forum.xda-developers.com/showthread.php?t=2448613
my GOD, what did i just read

Adreno 420? As a heavy gamers, this thing really make me annoying -_-
I have 600MHz GPU overclock implemented in my kernel for the Xperia Z1, which uses the lower binned version of the msm8974 (the one that comes with a stock clock-speed of 2.2GHz).
We have 450/487.5/533/600 MHz scaling steps.
You can take a look at the OC commits here, it's pretty straight-forward:

Is it possible to control also gpu voltage?
You got 600mhz at stock voltage?

It is, but not yet implemented on the nexus 5 custom kernels.
Also mhz does not mean voltage (V) or (uVolts on this case). MHz means a frequency of 1 million times per second (used on this case for CPU, GPU, RAM speed)

True, but @Carter07 is right that if the maximum allowed voltage is too low the GPU won't be able to sustain higher frequencies, as those demand more power.
The 600MHz OC is stable with the stock voltage, though, at least on the Z1 it is.

indeed, I misinterpreted him
You can flash Bricked kernel and use Kcontrol to force-overclock your gpu up to 650...but I wouldn't recommend anything above 550 since you will get little to no performance and it'll consume a lot more battery
Is there a huge performance boost noticable if you oc the cpu? And what's about the battery life?

There's no recognisable boost in performance apparently. And yes,battery drain will be higher if you raise voltages and you also risk damage to the core.

CPU or GPU? Some users reported less lags (OC GPU) with energy-consuming games.
Does GPU OC yeild any results in moto g ? As in gaming performance.
You need root for this and probably need a way to disable the CPU clusters.
What is the Geekbench 3 results for the following?
Only A53 cluster with performance gov (locked 1.5 ghz)
Only A57 cluster with performance gov (locked 2.1 ghz)
You need to monitor CPU utilization in order to know that only the wanted CPU cluster is being used.
Core 1 - 4 is A53 cluster
Core 5 - 8 is A57 cluster
EDIT: when running Geekbench 3 normally, can someone check if all cores 1-8 are used by Geekbench 3 for the multicore result by monitoring utilization of all 8 cores during the benchmark. If all 8 cores are used there should be vey high % utilization on all 8 cores during some parts of the benchmark.
Thank you.

Why?
Short version
I'm interested in the CPU performance of both clusters separately because I manage my phone performance (Note 3) with the help of
Multicore CPU Control PRO, and SetCpu with profiles enabled on screen off/on and certain applications.
I don't find the stock settings responsive and smooth enough so I adjust them.
