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).

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

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

First I'd like to say excuse my ignorance. So my note 3 was lagging bad after the update to the newest software so I decided to root my device. Not running a custom rom or anything but the main reason I did so was to be able to set my cpu to certain frequencies. So I have done the root. And have tried multiple app from no frills to trickster mod. But each one I have. It will not let me change the frequency above 1497600 mhz. Each time I click on save no matter what frequency above that one it always reverts to 1497600. I use xposed installer and thought I found a module to fix it (dvsf disabler) but if that is what fixes it ive still had no luck. The phone doesnt run horrible but there is a little bit of lag. Does anyone know why this is happening, and how I coukd fix this?
Anyone have any idea? If this is posted in the wrong forum please let me know, I'm just looking for a way around this.
If your CPU frequency is anywhere close to 1,497,600 MHz, I would like to have a word with the laws of physics, and inform it that it is broken. Simply put, there is a limit on how high your CPU can be clocked before it becomes hot as hell and unstable. The highest clock speed I have even heard of a CPU reaching is around 7,000 MHz, which was a very highly overclocked Pentium 4. Newer high end x86_64 CPUs generally don't tend to get overclocked to much higher than 4,000-5,000 MHz, although they are much more efficient with those cycles than a P4, and have the advantage of hyperthreading. Your phone's CPU honestly shouldn't be clocked higher than 3,000 MHz, and if it's a rather weak CPU, it might not even be able to be overclocked to higher than 2,000 MHz.
Or is it perhaps the case that you meant to say your CPU is clocked at 1,497.6 MHz (decimals are important!), and it won't go higher, because as I have just mentioned, there is a limit to how high you can go?
Basically 1.4 ghz. There have been people overclocking at way above that as the cpu is supposed to be around 2.3ghz.
Hi,
So I have honor 6 H60_L04 rooted .
I have better battery stats installed.
When I look at the CPU states, the maximum state it goes to is only 1.3ghz. I know this phone has like dual quad core, 1 for heavy processing, another for daily/light activities.
I've tried using performance mode, running antutu benchmarks, but the 1.7ghz state doesn't seem to appear at all under the statistic.
I've also tried normal power state mode.
Do you know any idea how to activate the fasterr processor?

honor 6 has two sets of quadcore processors(arm big.little configuration)
the cpu apps shows only the frequencies of little i.e, the little 1.3ghz processor and not the bigger 1.7ghz set
see cpu z app if you have any doubts
I believe the kirin architecture uses 4 cortex A15 cores and four energy efficient A7 cores. During normal use the A7s run at a max of 1.3ghz (fine for general use) and the A15 cores are under clocked. Then for intensive use (gaming etc) the A15 cores run at 1.7ghz
Here is an attached screen shot of my cpu-z
At the bottom of the screen, it says interactive governor.
But i did plenty of antutu benchmarks. Shouldn't that work the A15 cores to 1.7ghz? Or is better battery stats not showing me the second quadruple cores states?

More than likely BBS only reading the A7 cores. In CPU-Z for example, if I constantly click the square task button in the navigation bar and then click CPU-Z I can see the speed go up to 1.7Ghz.
Also until/unless Huawei release the kernel source there won't be any ability to overclock unfortunately... which is frustrating as the A15 can easily be clocked to 2GHz :crying:

Coool.. Thanks alot! The A15 does go up to 1.5Ghz+++ when i spam the screen or buttons while in CPU-Z. So it is BBS then that is not tracking the A15 cores. Thanks agaiN!
