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)

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

[Q] Is the Infuse underclocked from the factory?

I'm running CM10, and it's running fine overclocked to 1600 MHz, yet the phone is factory clocked, (with a factory ROM), to 1200 MHz. Why? My phone seems to run perfectly fine using SmartAss2 management, but Samsung apparently purposely underclocks phones for some unknown reason. Obviously stability isn't a concern, or it would crash at 1600 MHz. Yet it is stable, so why is the default clock speed so slow? Considering the phone is perfectly stable at 1600 MHz, would it be possible to O/C my phone to 2 GHz, or would I risk frying my phone if I somehow managed to OC it by that much?

uhh well.... yea and no. there are a few things you need to understand about microprocessors. no two are alike. they are built on a scale of a few nanometers and any difference causes a significant difference. to keep production numbers up there is a line they have to draw between performance potential and stability. more chips will be stable at lower clocks so they pick an speed they can get a high production number out of. sometimes a whole line of chips is produced with exactly the same core. chips that pass the highest get boxed as the highest performing and priced. chips that dont pass will either have specific features turned off, cores turned off or be underclocked and sold as lower models. in addition to that the top performing models are actually over priced, and often many more pass the tests than they need so perfectly good processors are intentionally disabled to fill the market for lower speed processors, so yes the cpu may be "underclocked" in a sense. but i don't know if that really applies to the infuse because i don't know if there are any chips in the same family that have a higher rated clock speed, if there are they aren't used in phones.
in example, on my pc i have a 3 core processor, it's actually a 4 core and i can even turn the 4th core on in bios, but a certain percentage of that particular model of chip will be unstable with the 4th core active.
another thing to understand is how the clock speed is set. there is a buss and a table of multipliers and dividers. so as one part of the chip oscillates at one frequency the multipliers and dividers say how may times per oscillation the other components go. the cpu speed changes by changing these multiplier values. the problem is that there are only so many multipliers the cpu is designed to use. this is a hardware limitation and can't be overcome so at some point the only way to get more clock speed is to change the buss speed which affects the entire system and will cause instability in most cases. occasionally you can get around this if you change the multiplier values for other componants as well but it's probably not a good idea to mess with it. the hummingbird chip only has multipliers to go to 1600mhz regardless of stability unless you mess with the buss, one developer got the galaxy s to 1700 with buss overclocking but some things didn't really work at that speed and it took a lot of changes to other system clocks. snapdragon chips can go to higher clocks and process numbers better but the hummingbird is better for graphics and multimedia which is more important on a modern phone imho.
so yeah 1600 is it, as far as practicality goes anyway. there are a few infuses that can only go to 1400-1500 as well and galaxy s phones which have the same clock limitations but are only rates for 1000mhz rarely go to 1600, but a few do, my captivate was absolutely peaked out at 1300, believe me i tried to get it higher, i tried a lot of things with voltages to try to get it stable, but even 1300 took some doing. it took a long time before developers even produced a kernel for the sgs that used clocks over 1200 because many of the early builds of the sgs series were much like mine and were not stable at high speeds.

Beautiful. :thumbup:

Is it possible to have a partially working processor?

It has come to my attention through benchmarks that my CPU is not performing anywhere near where it should be. It also has a -1C reading on Core 2 (technically the third core) in Synapse that occasionally flickers a temperature that is MUCH lower than the rest of the chip (like if the rest of the chip says 70, it will say 40 and it idles at 27C while the other cores don't go below 33C).
My AnTuTu is 62k and my AnTuTu beta is only 76k. In the AnTuTu beta, even the One M9 is destroying my chip (I only beat it on RAM score, Multi-Core, and 3D) - the UX scores are all about 25% under the throttled Snapdragon 810 and in the beta, the Note 5 should score almost 84k. The only benchmark that my phone is beating it on is the 3D benchmark (14602 to 13929).
If my CPU IS damaged... How on earth would I even go about getting T-Mobile to understand what I'm talking about? I mean the phone performs admirably anyway but if this isn't the performance I should be getting, I don't want to have a defective phone...

Is your phone working properly when doing phone things? Is it modified?
What software version are you on? Kernel?
We need all that.
By the way......scores don't really mean anything as It's a cellphone, not a gaming rig but understandable people want to test performance. Do you use your device mostly fire gaming? If so do you get any lagging dieing play now compared to before?

I just got a note 5 from t-mobile today and my antutu benchmark is 41022. Under the Note 4. Im thinking I should take it back. And I did a system restore.
Gonna be fun explaining this at the store.

1.6 GHz max and only using 6 cores...

Hey guys,
i just got my LG G Flex 2 here in germany for christmas and im very happy with it
But there is 1 but important (for me) problem.
It only uses 6 out of 8 cores and the max clock is ONLY 1.6 GHz...
in Antutu im even behind the LG G4 with that "SLOWER HEXACORE" ...
Can someone help me and tell me how to get rid of those 2 problems and get 2 GHz for the Big Cores?
Also, how to easily root my german H955 with Android 5.1.1 ?
Thanks for answers and help
Edit: I got "V15-c-EUR-XX"
Edit2: GPU runs 600 MHz max instead of 650 MHz ...what did they do with my phone
Edit3: I already checked temps, before you ask. 35-40°C max.... i dont think it should throttle at that low temperature.

Okay, now, on the next day it shows up to 1950 MHz for those 4 cores.
Seems to be a temperature problem at only 35 °C ...
Whats the easiest method for rooting the flex 2 (V15-c-EUR-XX) ?

I am not sure if for this phone is the same, but sometimes if u have low battery the kernel switch some core off.

Its normal,sometimes it underclocks the CPU and not always is phone running on 8 cores.... And what about GPU? Well,i have same distribution (DEU) and max is 600 MHz,but currently i have it on 305 MHz. Personally,i never saw higher clock of the GPU,and i own this device for almost month.
Edit: the GPU underclock may be caused by Energy saving mode. However,this has no impact on CPU,CPU-Z shows 1,96 GHz even in Energy saving mode. I had same problems too,CPU-Z showed 1,56 GHz maximum,after restart 1,96 GHz max.

Thanks for the responses. One last question. Why do i get only 60k in Antutu where others get 75k+ without fridge or such?

Well. about an hour ago i ran Antutu test and got 68 000 points. However,it was much worse before (first antutu test had 48 000 points and i was shocked). There are many things that can influence the score. For example-power saving mode,current RAM status (how many apps you got in background),battery percentage and temperature. Maybe best time for test is cold start,when you jump right to Antutu after start (of course not right after,phone needs some time),because you have lowest temperature,highest free RAM and no background apps. If i did such test, i would score more points i think. And last thing-the performance drops significantly when you do many tests in in a row (i mean 1st test and then in about 10 secs other one)

Yeah my performance also seems to increase over time. Weird.
And yes this soc throttles easily. But it doesnt get as hot as my nexus 5 was sometimes with benchmarks and is still faster when throttled. Would not call this processor a fail at all.
Still hoping that the SD820 will be better in thermals though. But this chip is still more than what I need.

How is the battery life when it runs on lower clock speed?
Can someone please use the phone with underclocked cpu (1.6 or 1.8GHz) for some days and post the experience on battery, temperature and phone responsiveness? Thanks.

Battery life is not improved when the phone runs in 1.6 GHz mode. I usually get about 3 h screen on time. The phone heats up a lot under load. I never saw my phone using the full potential with this Snapdragon 810 CPU. It always runs at 1.6 GHz and that seems to be fixed by the ROM on mine.
