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
-JChao

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] Dangers of overclocking the Sensation's GPU (Adreno 220)

Hey there,
I've read some threads about the dangers of overclocking an Android-device in general. I'm aware of these dangers.
But in my feeling overclocking the sensation is a little different.
Most custom roms set CPU-speed to 1500MHz each core, which is the native clock of the chipset (or am I'm wrong?). No problem so far.
But with tweaking the CPU often the GPU is overclocked, too.
Now the point: What are the dangers of overclocking the GPU?
Does it make sense to overclock just the CPU without the GPU? Is it possible?
What are your experiences with overclocking (e.g. with IsertCoin or RevolutionHD) the GPU?

What you have to remeber with regard to overclocking is that your not alone in doing it when you use one of the custom roms.
Many thousands of ppl are running overclocked handsets and the first things you see happening from overclocking to far is your handset not booting up or locking up well before you would do any physical damage to the handset i would say.
I have run my sensation at 1800 cpu speed and it started ok but locked up when doing one of the benchmark tools , i rebooted and reduced the speed a little but all running fine with no concerns with regard to overheating

So there is a hardware protection to prevent serious damage?

I dont know enough about the handset to say if there is or not i suspect there will be something , but have you ever tried to overclock a graphics card on a pc you get so far and it wont display or something like that so you reduce it.
Heat with any electronic component is i problem and overclocking something increases that heat, but when you get to a certain point your phone will lock freeze reboot etc usually before any damage is done.
If you have any concern about destroying your phone by overclocking the simple answere is that you dont overclock it .

Yes you're right of course, but i just want to get a feeling for this topic... i just try to decide if it's a good idea to use RevolutionHD, which is overclocked from the beginning.
And to get a feeling, I just asked about the risks, because the benefits are clear for me

To answer your question, yes, the sensation comes with thermal protection that helps against overheating. If the device becomes to hot, it(in most cases) shuts itself down until it cools. The CPU in the sensation is underclocked when it's shipped at 1.2Ghz(1188), but the true spec of the CPU is actually 1.5Ghz(1536). HTC underclocks the CPU to 1.2 to save on battery consumption. I personally have ran my phone just fine at the 1.5Ghz setting, I've even pushed it up to 1.6Ghz(1620) and it ran fine with the exception it did get just a little hot, but nothing to worry me. That being said I've since underclocked my CPU to 1296 and all is well. And afterall, how fast do you really need your phone to be before you take it too far and fry the cpu?? The sensation is fast right out of the box and even faster when using a NO sense rom, such as cm7(my personal fav)
Side Note : The new sensation XE ships with the cpu at it's original clock speed of 1.5Ghz.. both sensations have the 'exact' same cpu.
In regards to your GPU question, I have mine set @ 300mhz and not 320. The sensations GPU comes clocked at 266.I've ran it @ 320 and it ran just fine.. for me it's more of a personal preference. My graphics look just fine clocked @ 300mhz.. Below is a quote about the chipset and the new one coming out.
"With Adreno 225 Qualcomm improves performance along two vectors, the first being clock speed. While Adreno 220 (used in the MSM8660) ran at 266MHz, Adreno 225 runs at 400MHz thanks to 28nm. Secondly, Qualcomm tells us Adreno 225 is accompanied by "significant driver improvements". Keeping in mind the sheer amount of compute potential of the Adreno 22x family, it only makes sense that driver improvements could unlock a lot of performance. Qualcomm expects the 225 to be 50% faster than the outgoing 220."
if this helped, give the thank you button a punch
p.s. I've ran both insertcoin & revolution HD and both ran fine.. I just really prefer no sense roms

a few time ago some other user reported the same thing about adreno 220
but i think it is too high that value and it is impossible for gpu to handle such a value
in order to overclock the gpu you have to flash another kernel

Team EOS Nightly builds... Are they overclocked?

Since installing builds 29, 30, 31 I have noticed my battery life shrinking and the xoom running warmer. Am I imagining things or are these builds overclocked upon flashing?

Nope, not by default. I'm running EOS 32 and it came set up like this:
Governor: Interactive
Minimum Frequency: 216 MHz
Maximum Frequency: 1000 MHz
Maybe you can use an app like System Tuner to undervolt your Xoom? Not sure what else could be draining your battery so fast while warming your device.

It could be my imagination and maybe I am just using the device more and giving it a workout when playing with all these EOS builds.
Thanks for the clarification.

Can someone just let me know what overclocked exactly means ?
is it helps to make mobile/tablet faster ?

CPUs have the ability to run faster than they are clocked by the manufacturer. The tablet ships with a CPU clock speed of 1 GHz. This speed is specified because the CPU manufacturer has deemed it the optimum speed (in terms of stability and possibly power consumption) for that particular CPU. By modifying the kernel, you can add the ability to change this maximum (and minimum) threshold. Theoretically, yes, if you increase the clock speed, your tablet will run faster.
The clock speed is how many cycles a CPU can do per second. So, at 1 GHz, a CPU executes ~1,000,000,000 cycles per second. By setting the maximum speed to 1.5 GHz, your CPU can now execute ~1,500,000,000 cycles per second. A CPU also has an instructions per cycle rating. So the more cycles you can execute in a second, the more instructions your CPU can process in that second.
You must keep in mind that when you increase the clock speed, you may sacrifice battery life and/or stability (higher frequency needs higher voltage). Additionally, even though we all have the same CPU in our tablets, there are small variances. I may have no stability issues running at 1.7 GHz while you may suffer boot loops running at 1.7 GHz. Furthermore, running at a higher clock speed may cause more heat and electronics don't operate very well when overheating.
Finally, the governors are used to regulate the clock speed. Just because your CPU is clocked to 1 GHz, doesn't mean it's running at that speed 100% of the time. If it's sitting idle, it may be running at ~0.250 GHz (250 MHz). Then, when you wake up the tablet and open an application, the governor realizes you need more CPU power so it increases the "maximum" until either 1) You no longer need additional power 2) You've reached the maximum threshold set by the kernel.

"The clock speed is how many executions a CPU can do per second. So, at 1 GHz, a CPU can process ~1,000,000,000 instructions per second. By setting the maximum speed to 1.5 GHz, your CPU can now execute ~1,500,000,000 instructions per second"
Not sure if I am misunderstanding your lesson. Please understand this no attempt to troll or argue, but Clock speed is a reference of the frequency of the processor. They are basically saying your processor has an operating frequency of 1 Ghz. Instructions per second is measured by IPS (instructions per second). For instance, My AMD Quad Core processor operates at 3.0 Ghz but can handle 42,820 MIPS. They are not directly proportionate.

You're right and wrong
IPS is a function of clock speed so they ARE directly proportionate.
(Clock speed) X (instructions per clock) = IPS
I used "instructions" to simplify the example but you're right, I should be using another word.
Thanks for pointing that out!

Thanks skinien
I'm having motorola xoom ... planning to root it to have ICS ... any idea what will be optimal overclock speed for it .... mostly for playing games on it

From what I've seen, a lot of people stay around 1.5. Just make sure you don't click "set on boot" immediately. Use it for a while too make sure its stable at your chosen frequency.
Sent from my ADR6400L using XDA App

On ICS, mine is super stable at 1.4Ghz. My crashes, no reboots. And I'm using the Lagfree governor, so clearly I'm not locked in at 1.4 all the time. That's just the max speed based on CPU intensive activity...

Overclocking's effect on phone's lifespan

It seems to me many people overclock their HOX up to around 2ghz through various kernels/ROMs. I'm relatively new to Android phones but I do have a fair amount of OC experience on PC. The thing is, on PC the OC is generally well studied/tested by many people with well established thresholds, and people often upgrade their cooling system to accommodate OC. If stock cooler is used, there are usually established conservative limits. Furthermore, there are programs that stress test the setup to detect any instability. It's known that OC decreases hardware's lifespan, but if you do it right, that decrease can be negligible because of the realistic lifespan of PC.
Our phone is tiny and its cooling is not upgradable. If we overclock it by 30%, what effect will it have on its lifespan? Is there something about these S4 CPU's that I don't know about? Were they made to be able to easily handle the OC without any significant heat increase?
Please share your thoughts.

I'm not sure the true clock speed of the krait but I've read that most CPUs are under clocked by default
So I would think the impact would depend on its true clock speed
It also depends on how long you intend on keeping the phone. I change phones quite often.
If you intend on keeping it two years then I'd suggest just be safe and not sorry. This phone is fairly new and not much is know of long term issues quite yet
Sent from my One X using Tapatalk 2

i know the S4 can be clocked at different speeds by default (1.5-1.7 GHz Dual-core Krait). there is also superpi for android to test stability. it seems 1.5 - 2.0 GHz doesn't give much of a performance boost as far as benchmarks go imo. If we could somehow manage to tweak memory timings like on a pc that would be awesome.

OC = shorter life........to what extent I cannot say. But it's a fact
Sent from my HTC One X+ p_type 0.91.0

My P3 that was a stock speed of 733 an runs at 1.8ghz for last 6 years with factory cooling says don't worry about it.
Also, i couldn't hit 229ms in pi until 2ghz.
If your worried about shortening the life span, by over clocking, its not for you honestly.

[RESEARCH] Overclock on Qcom useless due to screened SoC's

Some weeks ago @Quarx told me that he tried to overclock his MotoG. At a first look it works. The system is stable and cpuinfo apps show 1.9GHZ.
BUT: there isn't any performance change. Then I checked it on my device(Xiaomi Mi2) - exactly the same result.
I watched a video about Nexus4 overclock: https://www.youtube.com/watch?v=96hsPe-JH2M
As you can see there isn't any change, too(the minor differences are just random).
Then Quarx found a very interesting commit in MotoG's kernel log:
https://github.com/Quarx2k/kernel-moto-g/commit/ed82c3f26ec4a7ab39a436647643bdaf71dcb67a
The message tells us, that QCOM devices normally are "screened" which basically means, that if your max freq is 1.2GHZ, it doesn't matter what you change in the kernel source. it will always be 1.2GHZ even if it shows 100GHZ because the SoC is limiting that.
There are some older SoC's with adreno 2xx which seem to be overclockable without any problems.
But all new SoCs seem to be screened which prevents overclocking.
Some more tests of other devices and SoC's would be helpful.

I'd recommend you get a buttload of single-thread Linpack benchmarks at different frequencies and do some statistical analysis. Maybe make a Google Form where you can input Device, Frequency, and MFLOPS
Linpack because it's exclusively CPU, doesn't vary much between devices of the same model, and scales nicely with frequency.

I think Linpack isn't reliable enough because it's completed too fast. For me it takes 1-2s to complete and the result variate's very much.
Sth like Antutu(only the CPU score) with performance governor and maybe even on a clean install would be better.

So how we can really test it? test in game to see if FPS get more high? I really dont believe that is just a placebo effect, in my kernel with 1.5Ghz I really feel the speed and will test when i finish the OC of 1.8Ghz.

well I only said that linpack looks unreliable. Antutu or other cpu intensive benchmarks should work just fine. Just ignore gpu benchmarks, because the gpu is definitely overclockable.
