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).

[POLL] Tested Dual-core ( 972 mhz) vs Single-core ( 1.836 Ghz)

Hello guys,
Since i`ve seen so many debates about single vs dual-core, today i was bored and i tested with antutu and quadrant this thing.( I know that benchmarks isn`t a real proof in day-to-day performance )
WANT THE SCRIPTS FOR UNDERVOLTING AND FORCING CPU1 ONLINE OR OFFLINE ? See 2nd post
SO , what I actually did:
-flashed a freshly new rom ( using elegancia 3.1.0 for about 2 weeks and i found to be very stable and smooth with better battery life than any other rom i`ve tested)
-flashed latest bricked kernel min 192 mhz max 972 mhz with gpu oc @300mhz, lagfree governor, I/O deadline, both cores online via init.d script, booted and tested with antutu and quadrant and then i let the phone settle for a while to see what is the power consumption in stand-by with battery monitor widget.
-after that, i flashed bricked kernel with only max speed change to 1836 mhz, cpu1 offline via inid.d script and made those tests again
Here`s what I got:
Antutu: 4827 (both cores online, clocked @ 972 Mhz)
Quadrant: 2592
BMW: -19mA
Antutu: 4593 ( cpu1 offline, clocked @ 1.836 Ghz )
Quadrant: 3393 ( cpu1 offline, clocked @ 1.836 Ghz )
BMW: -28mA
Those numbers doesn`t reflect exactly the user experience. Some apps opened faster with 2 cores, some faster with only 1 core clecked at higher speed. The only major difference i noticed was in the browser( stock ICS browser) where the more fluid experience was with both cores on.
I`m gonna test those 2 configuration further to see which one has better battery and post some screenshots.
I will add a poll to see which configuration you think is the best.

Be aware that SoC are not created equaly, so the UV script or OC will NOT work with all devices.
Unrar the archive and choose what you want
This files needs to be copied in /system/etc/inid.d and then set the right permissions ( read: all 3 needs to be checked; write: owner checked; execute: same as read) . You need a file explorer that has access up to root ( i recommand Root exploer)

Benchmarks should always be done using Performance governor for consistency

I knew that, but i wanted a more real-life experience, and in my opinion there isn`t that much difference in lagfree vs performance. I ran benchmarks 2 times and the scores where almost identical

Please be aware that because of the instruction sets hard coded at low level into the cpu it doesn not mean that 2x 900mhz cpu cores is equal to 1x 1800mhz cpu core because of the way in which the second core is utilised. Its exactly the same with pc's hence why sometimes an AMD cpu with 2 cores can give a better real world performance benchmark than an intel cpu with 4 cores. the same applies vice versa, it just depends on what instruction sets were used and how the cpu is used. Benchmarking stuff like this is not a reliable way to test

Thanks (I'd use thanks button,but i'm limited to 8 oer day) for clarifying this for me and any other users, this post should be sticky because many members on xda think that way. I am aware that 2x900 doesn't equal 1x1800, but I didn't knew the exact explanation. The only reason that I did these tests was to see which configuration gives the best battery life. Their not equal, but acording to antutu, quadrant and end user experience they are comparable

Thanks for your time in doing these tests... It might not be reliable but it was interesting to know bout it... Im curious between the two tests though, which test puts the cpu under more stress? the first test shows awesome result on the battery so being single core might stress the cpu more, im guessing

33% left and it's running for15 hours with 2 cores

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.

Snapdragon 810 - Core A57 disabled

Hello,
It's been 10 days that I have a Z5. After testing all, I told myself I was going to test the core of Snapdragon following the "problems" of the z3 +.
I am quite troubled. I use Folding @ home to test the operation of cores. The 8 cores It Works together have only a few seconds. 6 core (4 A53 and A57 both) Few minutes. And after-3 minutes, only 4 A53 and 1 A57 at 800mhz Work. In games it is a bit the same. To this are normal ? For me it is not a true OctoCore. Do you think there will solutions to force the use all core ?
Thanks

In simple terms; it is down to the app to decide how many cores to use. The app is programmed in such a way to utilize X amount of cores. When you run older apps what were written for 1 and 2 core processor phones they will use 1 and 2 cores.
So yes, not using all cores is normal. When everybody is using an octo-core processor phone, apps will use all 8 cores at the most efficient level.

Thanks to you answer. But i kown that. Folding is an app that use all core. I think Sony quickly disables core to avoid overheating. For me it's not normal. Z5 never use 8 core more than few secondes

Slightly offtopic but is there many other apps that would use all cores to test?

Yes (normaly) apps Benchmark test single cpu, (instruction, optimization) en all cpu like Antutu, GeekBench 3 ect....

Antutu will use all cores available to it but try running successive benchmarks and you'll soon notice that the scores drop lower and lower as the phone heats up. Now I don't know if cores are being disabled or the clocks are just lowered but either way, you can't use all 8 cores at full speed for long...

Yes agree. i'm slightly disappointed on this point. That all ^^

See now I just recently got the Z5 over my half broken z3 cause it's a 8 core vs the 4 core in the z3, but even with Antutu it only uses 4 cores, even when they're completely maxed out. I've pretty much gone from a 2.5 ghz cpu to a 1.5, it is they programs are not reading it or they're just not being used?
It's kind of infuriating really, if they won't be used ever I will send it back and get a higher clocked 4 core cpu phone.
Some times core 4 is used, slightly, would a custom rom be able to fix the issue with core not being used??
Benchmarking software should be able to max out all cores on a cpu.

Some CPU cores don't go to idle

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?
