Benchmark on captivate

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).

[Q] How many of you run overclocks on your android?

just debating over should i overclock my phone and the pros and cons.
so was wondering what frequency people were running their phones at

I overclock up to 1200/1300 MHz without any stability issues. The main reason I require this speed bump is for demanding games such as GTA 3, Shadowgun, and Modern Combat 3.

i will go ahead and try 1.2ghz i dont susally play many games but i have felt the systema bit slow when multitasking a lot so hopefully this will help.

same here I feel ICS is bit slow so I oc to 1.2g

I overclock to 1.2, although I think realistically it doesn't do much since I hardly do anything demanding like 3d gaming. I really just OC for bragging rights...

I generally OC to 1200. Remember that it only clocks as high as it needs to (thanks to various cpu governors, default is ondemand), most of the time it will be around 800 - 1000mhz while in use from my experience. So long as it doesnt get particularly hot (say 35C+) and you don't get reboots/sleep of death/general instability, it is quite safe. I'd imagine the 1GHz they clock this cpu by default is more due to cpu variation during manufacture, to guarantee all chips work perfectly fine. Some phones will be more prone to instability while overclocking than others because of this.

I'm also interested in OC-ing, so maybe you could also post some voltages if your configuration is stable. Thanks

i tried oc but my phone hangs on some apps, so i only oc on certain apps only

Phone gets hot. = faster battery drain.

1200 or 1400 mhz
i overclock to 1200 mhz and all my apps/games work fine. When i need to play games like modern combat and gta 3 i overclock to 1400 mhz (just to get better gameplay)

[Q] Underclocking battery life. Underclock too much?

So I have a quad core 1.5ghz. I under clocked it to 486mhz. I have been watching the processors and at what speed they are running. I find that most of the time for basic things one or 2 are running. But if I raise it to 594mhz or 702 the second one and the rest kick on less. Would it be more energy efficient to run one at a slightly faster speed vs running 2,3,4 more often at a slower speed? I locked the cpu max speed. For some reason the second one would run faster than what it was set at. So maybe I should undo the force lock because it might be more energy efficient to let that processor be the only one to go faster?

Max CPU speed

Both cpuz and CPU spy report 1500 mhz as max speed for the processor. Is this normal?

Yes. Ish. The phone has 2 processor chips clocked at different speeds. One for general pottering about, and the other for heavy stuff. But for some reason, apps only report what they are told about the light weight processor, which is at 1.5Ghz.
But on CPU-Z, I was able to catch a glimpse of the other 4 cores of the heavy duty ones touch 2100Mhz (2.1Ghz) briefly. So the phone does perform correctly, but the apps themselves don't report the info as we'd like/expect with a 2 processor device. Yet.

Bad performance in GTA:SA and not only? (Adreno-related)

Hi there! Any devs here?
Maybe anyone knows why in few games Adreno CANT BE on 100% usage?
For example: my phone is Pocophone F1. SD845, Adreno 630. Usage in any benchmark at 100%. Minecraft: 414 Mhz (instead of 710 Mhz - max for MIUI kernel), 80%, 50% usage in total.
At the same moment Mali at 100% usage with a LOT bigger FPS. Same with GTA:SA, possibly Modern Combat 5. What's happening? Any fix?
Maybe game devs should do something like PC game devs do?: (enable NVidia Optimus, bad example btw) vOptimusEnablement = 0x00000001 (just an example).
P.S. Oops, forgot. Throttling disabled, 5 minutes in CPU Throttle Test shows no difference (5min enough for this because the game started lag at the whole start).

All programming instructions ( whether they are graphic information or not ) are first processed by the CPU: if the CPU recognizes that they are graphics commands, they are delegated to the GPU. Unlike a CPU - which has only a few cores - a GPU has hundreds of cores.
Throttling the CPU only makes things worse.

As i said there's NO throttle. Fully disabled. That's happening on any Kernel. Idk what is this, Adreno-related thing, no problems at Mali with that.

Of course. Maybe Adreno-drivers need something for this? To say to CPU "Hey, this is an application that needs a lot of GPU power"?

An app neither speaks to CPU nor to GPU: an app's program code gets loaded into RAM, then read in from there by CPU and sequentially processed.

What are you talking about, lol? The game cannot use GPU. It needs something. Maybe some function to call, idk exactly.
You're speaking about completely another thing that i know for almost 12 years, lmao.

Still waiting for any answer. Few games cannot load a GPU. Only on Adreno, Mali GPUs are good.

My last 2 cents here:
A GPU is a processor with hundreds of cores: a game never can load a GPU, it only makes use of it.
For an ideal situation, your device's CPU usage should remain in the 60% to 80% range (up to 90%), and device's GPU usage at 99% or 100%. One of the main causes of low GPU usage is due to CPU bottleneck. It means that you have an under-powered CPU that is not able to keep up with GPU's performance.
A temporary workaround for this problem is to raise a game's resolution to highest if you haven’t done it already. This will cause device's GPU to work more and it will have much higher utilization than before.
Take note that not all games use all the CPU cores. It can be possible that you are getting high usage on two cores only, and others are just not used at all. AFAIK GTA SA makes use of only 2 cores, COD also makes use of only 2 cores, , but PUBG makes use of 4 cores,

What the hell are you talking about?
Is there any CPU bottleneck im talking about?
NO. NO. AND NO. ADRENO-RELATED, HUH?
Pls, stop it, my chair burns. You dont understand a single thing that i need - ADRENO CANT HANDLE A GAME.
Looks like a joke...

Actually, I'm not interested in your problem at all.
Your posts show that you don't understand how CPU and GPU work together.
Here I'll explain it to you:
The GPU's memory consists of a series of registers. These permit the CPU to access the GPU's memory and instruct the GPU to perform operations. It's the CPU what loads the graphics instructions ( OpenGL ES ) to get executed into GPU's memory.
Simplified: the CPU feeds the GPU.

My post shows that GPU cant handle few games. All Adreno's. GG guys, open your eyes

Still waiting for useful info. For now stop showing your brilliant mind with yours "i think you..."

After a time and with using of a simpleperf i got more info. Playing Half-Life 2:
CPU Usage 12.12% /vendor/lib/egl/libGLESv2_adreno.so
Symbol: !!!0000!f56be09eb88f86833124f1df42e945!95db91f!
Mali HAS NO that problem. Completely.
