Hi guys
I downloaded the quadrant standard application on my Captivate. Looking into the system info i observed the following
1. CPU : samsung cortex v7. I thght the processor was a v8? I dunno whether the processor info is right.
2. The processor speed is displayes as "800 MHz"
Max freq ; 1000 MHz
MIN freq : 800 MHz
Whatz going on here?
Can someone explain this?
Please run the benchmark and lef me know!

the 800mhz I would assume means it is throttled down.
My results...
Name: ARMv7 Processor rev 2 (v71)
Current freq: 800 MHz
Max req: 1000MHz
Min freq: 100 MHz

Just ran the benchmark and got the same thing. Please don't tell me this thing is underclocked. if so is there a program out there that will bring it up to speed?
The processor is a Samsung S5PC110 Cortex-A8 and uses the ARM v7 instruction set. It's not a version 8.
there is an APp to change your CPU clock. Don't do it though, nothing on android requires those extra 200 MHz yet. If your thinking about UI Lag, this is a software issue and not a consequence of the throttled cpu. Hang tight for a fix from developers.
With the software fix and throttled down cpu, this phone is still faster than the newest phones running 2.2 (Froyo)
SetCPU will let you force the frequency. But you shouldn't need to use it, 800MHz just seems to be the Hummingbird's idle frequency. The CPU probably just idled while the graphical benchmarks were being run.
CPU in phones never runs at 100% at all times that would kill battery , you can force it if you root your phone but that is counter productive , as it goes from anywhere from 1% to 100% of its speed when it needs to , during intensive usage or benchmarking it will reach 1000mhz , but if all you do is read text it will conserve battery.
Its obvious from this info below
Current freq: 800 MHz
Max req: 1000MHz
Min freq: 100 MHz
Yes, the Cortex A8 is an ARM7 processor. The older CPU's used were ARM11 processors.
Thankx for the info guys..
I checked again and for some reason i got confused with the processor and was writing the post from memory (my memory ). it says ARMv7 Processor rev 2 (v71).
And yes i do think the 800 MHZ is pretty fast.
I just need to get rid of the samsung UI and switch to stock android.

The spec sheet lists 1 GHz, and spec sheets show the operating frequency so I would assume that the CPU can run at different speeds for different workloads. Try running a couple heavy applications in the background and check it again. If all is well in the world it should clock upto 1 GHz.

The processor is NOT 800mhz it's just throttled down to 800mhz cause of not needing the full 1ghz speed. That saves power and battery life gets extended. Laptops and desktops do the same thing.
so in other words it basically adjusts oh and also maybe the ARMv7 infrastructure is better then the 11 one
yes i do get the idea

I do get the idea!.. i inquired about it bcoz nowhere it was mentioned that the processor was underclocked.. So basically the ideal processor speed is 800MHz and it can be overclocked to 1GHz is the way i see it!
sorta like that more like the speed auto adjust to your needs i think
So what kind of scores does this phone get in comparison to other new Android phones with or without 2.2. I am curious between the Quandrant scores of Hummingbird (Galaxy S), OMAP (Droid X), Snapdragon (HTC HD2/EVO 4G).
Thanks.
well the hummingbird beat the evo 4g in graphics and cpu power just search captivate benchmarks on youtube the channel name is androidandme
with mimocans lag fix ive seen people get scores as high as 1700(nexus one on 2.2 gets about 1250).

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
http://www.androidbeat.com/2013/09/difference-snapdragon-800-2-2ghz-2-3ghz/
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.
what is difference between T-760 MP6 and T-760 MP8 ? ( except Number of cores and Maximum Frequency )
edit : less power consumption
what is T-760 MP8 lithography ?
edit: its 14nm
I use lenovo vibe p1a42 which have Qualcomm MSM8939 Snapdragon 615 with octa core processor. When I viewed the CPU on cpuz and droid info apps, I found that the cores 5,6,7,8 never go to idle. They are always clocking at minimum of 800 MHz even when I don't open any app. While the cores 1,2,3,4 clock and stop normally.
What do you think about that? . Do I have a problem?
My s10e is rooted and i want to unlock full cpu speed.
Can i overclock the cpu and the gpu.
