So I've gotten anywhere between 2.5 to 5.1 MFLOPS using various ROMS and have yet to be able to notice something incredibly different.
710...768...806 - What does it matter? What program other than Linpack shows a sizable difference? Sure, maybe things open quicker? What am I missing here?
I read all this about achieving high MFLOPS and OC Kernels yet I still can't achieve smooth game play on 16 bit emulator on my phone with 5 MFLOPS.
MFLOPS mean jack when there is little way to observe the difference.

Linpack MFLOPS - measures the floating point performance of your phone.
710...768...806 - refers to CPU frequencies
increasing the CPU frequency should equate to better general-case performance, including things opening quicker as you mention, but also other types of general snappiness like moving between screens and so forth.
"I read all this about achieving high MFLOPS and OC Kernels yet I still can't achieve smooth game play on 16 bit emulator on my phone with 5 MFLOPS." - This may have less to do with the performance of your phone and more to do with the emulator itself. Emulation is a surprisingly CPU intensive operation, especially if the emulater isn't well written. Rather than looking a ton into overclocking and JIT, etc, maybe you ought to look for a better piece of software.
Yea,
I've tested most emulators. Wish there was an Atari emulator!
Thanks for the response.

Haha Awesome
it looks like to me that everyone is look at the wrong things.
for example:
I am running a Tom that is getting on a average of 4.9 mflops.
I get smoother screen changes....
streaming videos online is so much faster compared to a 3.0 mflop rom. ...
tubetube and other....... websites.
to me everything I do is faster...
I.don't play game on my phone so I don't know how that is.... but everythng else I do is very much faster.
I love high mflop roms...
I have notice about mflops is that it matters about the kernal that u use.
Isn't it true that the MSM7201 in our phones is already overclocked to get to 528mhz as it is? I see a lot of different places saying Qualcomm chips in general are just not worth overclocking... and since our chip is factory overclocked to begin with... just seems like we're pushing the already-pushed here. But the way this board goes crazy for overclocking... it's contradictory. I don't know what to think, cause I've run Linpack myself and gotten ~4.9 with JIT + OC versus ~2.5 without... but I'm with the OP on this one... only difference I'm seeing is my battery draining faster and my phone getting physically hotter.

I have OC and JIT and getting about 5.1 mflops and haven't had worse battery life or a hotter phone. It could be the battery I'm using but meh (got a replacement one that's 2000 mAh) but I got worse battery life on leak 2.1 than with the rom I'm using now that has OC, JIT, LWP, etc. I can go about 8 hours with heavy texting, moderate internet usage and my lwp's running and it only goes to about 65%
so OC and Jit don't make that big of a difference in gameplay?

What the OP and all the respondents are noting is frankly quite typical of what happens when performance tuning focuses on a single benchmark: the results obtained are essentially meaningless for different kinds of activities on the same device.
That's because there's a whole chain of dependencies that are specific to a given task, any number of which could become the rate-limiting factor; and a different task on the device will have a different set of dependencies and therefore different rate-limiting behaviors.
For instance, let's take writing to an SD card as an example: there's really no way that OC'ing will speed that up in a measurable way - because the CPU isn't the rate limiting factor.
That Linpack benchmark measures floating-point performance using a software library (as the Eris has no hardware FP capability). Most of the apps on the phone do very little FP work at all. But, it's not a bad test of CPU speed, because it performs no I/O. It also may not be very memory bandwidth intensive, either (if the problems it works on stays in the uP cache and there are few page faults).
OTOH, a game emulator needs to write to the graphics display (at a minimum) and possibly also do read I/O from flash.
Different task, different results. Sometimes things can be improved by hardware or firmware; sometimes the software itself needs to be improved.

Thanks for my laugh of the day on that one.
What I'm trying to get at is -
I should be able to play, at the basic level, Sonic or Mario - Without issues.
At the very least
I prefer roms over market games any day (Sonic, Mario, Zelda, DK-Country) and it cripples the phone, at least in my view, that I cannot enjoy the fruits of old games.
Although, I was able to find some old Atari games - which, thankfully, work without stuttering.
There's a chance of me purchasing an Atrix 4G and would like to ask some question beforehand.
1) Why do people say not suitable for Bell device on ROM? Is this the worldwide version? And not AT ver.?
2) How smooth is the screen, I mean when swiping, since I came from a iPhone 4 to HTC HD2 and I didn't like the screen as much.
3) Framerates in games? Any much difference compared to LG 2X (Seem some benchmark like 10fps-15fps average lost etc)
4) Does every or most games work? I mean support the resolution?
5) How would the quality be in 1080p in the future update since its a 5MP camera?
6) How many RAM in bootup? 750ish?
7) Battery life? Heavy & Average
8) I've heard the Atrix can get quite hot like the 1st gen snapdragon? Or is it the battery?
Regards, I'm sure a few have already asked this or looking for the same answers.
Sent from my HTC HD2 using XDA App
1) Why do people say not suitable for Bell device on ROM? Is this the worldwide version? And not AT ver.?
Ans: ATnT version released first and got i think two updates (mostly bugs fixed) and due to this reason developers started working on ATnT and developing it mostly, but as soon as Global Generic version will release bye bye ATnT.
P.S:Root is available for all devices (bell and ATnT.
2) How smooth is the screen, I mean when swiping, since I came from a iPhone 4 to HTC HD2 and I didn't like the screen as much.
Ans:After a fresh reboot choppy for 5 min max after that no lag at all.
3) Framerates in games? Any much difference compared to LG 2X (Seem some benchmark like 10fps-15fps average lost etc)
Ans:Most of the games are now optimized for Tergra2 so no more FPS problems.
4) Does every or most games work? I mean support the resolution?
Ans:Yeah.
5) How would the quality be in 1080p in the future update since its a 5MP camera?
Ans:I think 1080p recording will be ok. after all it is a mobile phone what u expect a 60fps video ???
6) How many RAM in bootup? 750ish?
Ans:With the help of Android System Information i am able to check that 818mb of ram is showed (must be reserved by GPU and DOC ****) and out of 818 570mb ram is available for user and after usage of 2-3 days i am still having 400+ available ram for usage and no slowing down or lag any ware ever.
7) Battery life? Heavy & Average
Ans:My friend play lots of Fruit ninja on my mobile (1-2 hours straight) and that wont even budge battery. And i use internet via Wifi quite a lot. so Heavy usage 1 day and if u use aveerage (sms calls and email then 1.5-2 days max)
8) I've heard the Atrix can get quite hot like the 1st gen snapdragon? Or is it the battery?
Ans:1Ghz Dual core phone (processor with 6-8 cores {audio,GPU.etc}) little hotness is there not burning hand and stuff.
P.S:heavy usage can even make iPhone warm (personal experience).
Hope this answers ur concerns.
So I overclocked my GSII to 1.6Ghz, and ran benchmarks and it was blazing fast. So what's the point of overclocking other than running benchmarks? I'd rather not have my processor running at 1.6Ghz all the time and draining battery power. I actually prefer underclocking to save power. So my question is - how else can I benefit from overclocking my device?
yo whyd you put this in the dev section? get flame suit on brotha.
miui+siyah = beast
Well its obviously to have your device performance better. Honestly it's not really practical to run higher than 1.2 ghz though.
You also put this in the wrong section. Prepare your anus.

But in what ways other than benchmarks? Am I really going to notice a difference if I kick it up to 1.4 or 1.6Ghz when browsing the web or playing Angry birds or something?
where is the download link and what does it do?
Some serious development going on here.. [\sarcasm\]
OP even if you crank it up to 1.6GHz, unless your isolating that step, your phones not using that clock speed unless your doing sh*t on your phone. It will increase how fast apps or menu's open navagating throughout the phone. Your making the CPU think faster so your phone ends up doing its tasks little and big ...faster
But dude.. Googling the benefits of OC could have giving you an answer ..and FASTER. Lol

The benefits of overclocking you ask? Let me tell you just a few.
1. For every overclocked phone, one dollar is anonymously donated to poor and starving children, families, and college students across the world [citation needed].
2. Overclocking your phone emits a low frequency gamma wave inhibitor which in some cases, tested by prestigious scientists, has proven to protect you from harmful UV rays from the sun, nuclear fallout, increases neural synapse action in the brain, lowers bad cholesterol AND blood pressure, increases lifespan up to a minimum of three years, and is a natural antimicrobial agent that also interacts with your white blood cells to not only increase output and strength, but also breaks down the DNA rebuilding process by inhibiting protein synthesis in a wide variety of foreign microbes in your body.
3. Overclocking has been used to successfully treat sever depression, obesity, dementia, and AIDS.
4. With an overclocked phone, it's been observed waiting times for and inside elevators is severely decreased.
5. Bad driver? Accident prone? Overclocking has been shown to heighten driver awareness and overall skill.
6. It speeds up your phone on a day to day basis, with some, but not terribly noticeable battery drain [citation needed].

Overclocking is entertaining. But I'm running the Unnamed rom on my device and have it UNDER clocked to 800mhz. Crazy good battery life and zero lag.
Overclocking is pointless as it runs everything great already. I'm waiting to overclock until my phone is outdated and my contracts about to expire.
While its rather easy to do there really isn't any benefit to overclocking the SGSII. Yes, it'll run a little faster and your Angry Birds might run smoother (really? ), but it'll also mean a little more heat and more battery drain all to accomplish something you really won't be able to get any real advantage from.
another reason to overclock would be bragging rights

For this phone, it's pretty much useless. The phone runs great without the faster clock speeds.
On the other hand, if it was a snapdragon processor, you'd need 1.5 GHz just to be marketable next to this phone (and 1.8GHz to perform as well in day to day usage.)

Most people overclock for a smoother/snappier experience. I notice that roughly 20% increase in scrolling/tabbing around. Also you can think of it like this:
1.4ghz will finish tasks faster then 1.2, that way taking less battery. You could also undervolt that 1.4 to 1.2 (1275mV), so your finishing tasks quicker while draining no more then stock.
I switch between 1.4 and 1.0 every other day it seems. 2 months later, still looking for the right one for me. 1.6 should only be for benchmarking imo, epeen.

It's not that simple.
There are dozens of bottlenecks in these devices (and any other computer), and 9 times out of 10, it's NOT the processor. Persistant storage, RAM, bus speeds, etc - all those things will ensure that a 10% bump in processor speed will NOT give you a 10% decrease in run time for a given typical application. In many cases, you'll see no speed increase at all, as it takes the same amount of time to flush to persistant storage no matter how fast the write cache fills.
I'm not suggesting that a person shouldn't O/C, but don't be surprised when going from 1200MHz to 1400MHz makes no visible difference other than the battery draining slightly quicker.
I know someone is going to respond that the processor will bump back down to a slower speed and therefore it runs at the higher speed for less time, etc. However, unless you have the governor set to poll for usage so often that the governer is driving your clocks up to max, it's not going to poll often enough to make much (if any) difference.
Think of it this way: We both own a mustang, but mine is a V6 at 220HP and yours is a V8 at 300HP. In theory, yours can accel faster and maintain a higher top speed. In reality, neither one of us can go faster than the car in front of us (but you'll burn more gas doing it.) (Of course, you'll have more fun in yours.)
I hope this helps with a very common misconception.
Take care

Very true. Also I am guessing in gaming, that OC will drain your battery quite well.
Consider I mostly do Web browsing on my phone (I need a tablet), 1.4 is a much better browser experience imo. Worth the 100mV.

While for now Overclocking is mainly just done for fun im hoping that closer to my upgrade time that i will be overclocking for more actical reasons. That is the way it was for my Captivate. I enjoy trying to push my hardware to its limits. Ive gotten my GSII so far to a stable 1700mhz but i think i can squeak out a little more speed especially with the gpu down clocked a little. I run it at 1400MHZ Though with the gpu forced at 267mhz.

I've read on several ROM forums that only certain apps utilize or dual cores. go to sys/devices/system/cpu/cpu1 there is a file there. When using one of the above said apps it populated cpu1 with freq folders etc, changes that one file from 0 to 1 enabling it. without one if these apps there is no freq tables for cpu1.
****my question: using Linux and cpu i ran speed tests. Over 70 tests in total. There is zero performance difference in using one app versus another versus cm performance cpu menu. I understand how it looks like two cores are only utilized from certain apps looking at the folders. However it does not change performance at all. Tests show same speed any way to control cpu. Also feels the same. Is there really a difference our is it monkey say????
Also in my tests i found using "VR" versus sio or noob or cfq to be the fastest. I didn't feel a difference however changing i/o setting.

Their are claims that Intel’s internal handset testing has shown multi-core implementations running slower than single core, however they did not cite any particular chip. If you take a look a lot of handsets on the market, when you turn on the second core or having the second core there [on die], the [current] leakage is high enough and their power threshold is low enough because of the size of the case that it isn’t entirely clear you get much of a benefit to turning the second core on. In some of the use cases they cited, having a second core is actually a detriment, because of the way some of the software engineers have not implemented their thread scheduling properly.......
That being said, one could argue the concept that a single core chip, running a slight overclock, would produce a far better result, than a dual core application. But again, thread scheduling detracts from any governor efforts anyway...IMHO....g
Hum. I would have to agree then that in our case and in my tests dual core doesn't help nor hinder performance results but does appear to reduce battery life. Now these are my tests using two different programs to test performance and using combo of setcpu/system pro/Cm10 performance built in/Tasker to control cpu. I have done enough testing to know that on cm10 roms dual core, or so the sys files indicate, is of zero performance upgrade and appears to drain battery faster.
Sent from my SGH-I717 using xda premium
Yes ...I agree with your findings.
I suppose it's safe too say then, when using the AOSP rom source, within it's normal configuration, that unless development is done beyond the current schedules, the stated performance is well ....overstated ??
Of course , CM is in a constant state of change, and I suppose that after they are finished with the functional repairs, they may focus more on the kernel.
I'd be very interested to see your same tests against another kernel, say flappjaxxx latest JB build.
I do know that he, and several other developers have made some great improvements to the source kernels, and although there will likely always be bugs present, after running my own evaluation of them, the governors are functional and do make at least a perceived difference.
But as you stated, albeit at the cost of battery life.
I choose not to overclock, as I feel that the marginal reward , as proven by your testing , and by testing from several reputable sources, is simply not worth the risk ...g
I agree Greg, i will test other kernels... Samsung ROM is probably the only one i won't test... I also don't overclock, i do under clock at work and screen off using Tasker for battery life. That does help greatly. I'll post back after testing different kernels tonight.

Thanks to you, for your inspiring thread. I look forward to the forthcoming information ....g
Ok with out posting tons of pics i tested all available kernels (new). Results were the same. No real difference in single core versus dual core...
The following pics show how to know whether the second core is online or not and my results and how i tested this time around... I was more through the first time but results the same.

I am posting pictures for first time hope this turns out.
What do you use to disable the second core? Read this with some interest. Would like to try this with ics Rom. With oc'ing fRom 1.56 to 1.72 i see a consistent jump of 300-400 in my antutu scores. Currently on flapjaxx ics b4.
I know it is just a score, but is your score indicative of the cm builds? It just seems really low.
Here is my 'stock 1.56 speed' with ondemand governor. Want to a get a single core sample.to compare with it.
How interesting ....
I can say that both of your posted results lead toward our initial assumptions, that indeed we are seeing a consistent draw against the systems cores with little or no improvement upon activation of the second core.
Some Time ago, shortly after my note arrived, I began some simple tests with low speed dual core activation. My thought process was simply this.
Slow speed dual core operation (both cores running in the 650mhz range ) would ideally produce a faster process response.
My initial results were favorable, as I had a noticeably quicker device during screen transitions, and even in several multitasking functions.
I even went so far as to create a small script to handle this function for me. I'm no developer, and ultimately I didn't possess the programming skills I needed to complete and implement my script into an actual, flash worthy modification. And based on what we are seeing here , the results provided would indicate that my attempt is flawed due to chip current leakage, if the cores are allowed to ramp to high, and perhaps even the use of improper source schedule interference.
I'm so busy these days, I simply haven't time to explore the low speed theory further at this point.
But perhaps with your test bench already set, a simple test using my concept could be carried out??
As we know, CPU [current] thresholds are plagued by voltage bleeding at maximum CPU frequencies, but the thought has just occurred to me that [current ] bleeding is highly controllable when the CPU is driven at lower voltage inputs. And too combine a reduced frequency with reduced voltage over a multiple core platform, could, or should balance the loss and equal the output levels.
Are you up for another test ??
If so ....I suggest the following parameters.
Core "0" at 600/700 MHz
Core "1" at 600/700 MHz
Governor at "interactive "
Voltage at "-24Mv"
Then we'll see if the theory holds water.
P.S. thanks gents, I'm enjoying the heck out of this thread ......g
Mad383max, look at your folders from my pics to tell if two cores are running. Typically on after market roms one core is running until you enable the second from other software like from my pics.
Will test at lunch. I like this lower voltage idea. If i were a betting man i would guess with speeds you proposed and two cores i would guess similar to higher results. Let's see....

I have to reflash ROM so pics might be a little awhile. I messed up some things and somehow lost my Google account. reflashing gapps and ROM didn't fix it.
Anyway results were 2600 something at 700 both cores underclocked 25... Slightly more than half of normal speed at slightly less than half clock speed... For kicks i tried 1.5 clock speed undervolted 75 (most my phone will go without lockups) and got 5k results. Best yet.
You are on to something. Less voltage = more speed. I now need to try single core undervolted. Give me couple hours for pics etc.. Got to get phone working with Google again and spend time with wife. She hates me on the phone.

No worries Troy. ...
Take all the time you need.....
I do appreciate the excellent testing you have undertaken. I know that the results are going to benefit the community.
And i am highly intrigued by your first run under the parameter set you've chosen...
It's leading down the exact path that i suspected. ..
I'll talk with you soon. ...g
A few additional items that I have failed to consider during my testing, could weigh heavily on our testing results and should be considered during testing.
They are, battery power levels, charger connection and type....(wall/PC), and rom power save levels.
I do know that the android OS will adjust itself during varying power levels, much like our setting the CPU to UC/UV settings, only on a much smaller scale.
I feel its important that we are able to control the input levels in the following way...
Battery to full charge, with no charger connection, and if the cable is needed we use a non powered port. Next would be controlling the rom power settings if the rom contains them, as found in most GB and ICS builds.
If these baselines are met, we should be able to greater rely on the mark scores we are seeing. These variables could explain why we continue to see so many peaks and valleys in scores when two users share the same builds, on like devices.....(speculation)..
Additionally, are we able to control the background processes to the extent, they will remain constant for testing?
Sorry for the rant.....Im just concerned about the ability to quantify our findings once testing is complete.
Ive started some tests on my end as well, and certainly do not want to give you the impression that I expect you to do all of the work.
After all, you did ask first....lol and I feel like Im dumping this effort into your lap.
And please forgive my pathetic punctuation in this post, as my keyboard of choice decided to fail tonight....g
Battery does effect performance greatly.... Also noticed none of the apps to test are very repeatable. Fluctuation seemed to be about 100.
Having issues up loading pics from phone, I'm away from laptop for a few days.
In the end i found -12 v single core to provide the best battery and performance that was equal to dual core. I tried over under voting many differences.... over voting did nothing, under voting a little made small preformance improvements. I believe some of fluctuations are related to app, battery, etc.... In the end it's too say dual core has no speed improvement. I would be cool to test an app that it's specifically for dual core. I am better off without the second core speed is same anyway, and battery is much better. There is definitely voltage leakage..
Let me know what y'all find in your tests....
Sent from my SAMSUNG-SGH-I717 using xda premium
Outstanding !!
I appreciate the hard work !!
So it seems we are better off using the note running a single core and about 12mv under volt.
And I'm of the belief that our second core is rather pointless...unless it can be proven that the second core is absolutely needed to perform a function.
And so far, I haven't found anything I use that requires activation of the second core.
I'll continue my tests, but the way it looks now, Intel is right, and Samsung pushed a dual core chip to this device for nothing more than a market share increase. As it is quite clear that the device does "not " need it to function well, and at a Very respectable speed.
Now we have a quad core version, and I highly question the motivation behind that move, beyond marketing as well.
These statements may offend some, and folks will certainly disagree, but if you want a great running device and great battery life, you need a single core chip ...IMHO ....g
Agreed Greg. Someone will get upset when they do thirty own tests and realize what we see, and what you said, good marketing by Samsung. Numbers don't lie and i did tests as controlled as possible. Even my battery shows in the picks... A true second useful core would have easily bested the single core results. Plus undervolting tella the bigger story...
I must say though. It had been very useful.. My battery life is so much better now!!!
For me the only true performance gain had been from v6 supercharger.

Fyi: same exact results using cm9 versus cm10. Neither ROM benchmarks faster than the other as of 9/16 cm9 and 9/15 cm10 builds. Dual core zero performance upgrade.
Tried quadrant again and result very up to 20% back to back so that app is useless to me.
Can someone try a Samsung based ROM. I'm curious add to a difference in roms. just use antutu benchmark and set cpu however you wish to whatever you wish just report cpu clock speed, type of test, and results

Out of town this week Troy, but i'm gonna bump it for ya...g
Hello everyone!
Right, I bought my htc two days ago from o2 on PAYG off course, I did my own research about the phone and I was happy with the results soo, I bought it.
When I play a game like GTA 3 with a stock settings I get some sort of lag for some reasons, although I thought, because it had the Tegra 3 chip it should run any game without any problem.
The phone is 100% stock!
here is some info in my phone that might help;
Baseband: 3.1204.168.32
Build number: 1.17.206.1
Does anyone have similar problem with the HOX+?
Also, my signal drops sometimes and it does not regain for some reason unless I go to flight mode, ON then off, back to normal. I am with o2/giffgaff, any ideas?
Thanks for your help!:laugh:
AW: [Q] My htc one x+ is laggy while playing a game and signal drops?
There are some major discussions going on around the web regarding gaming performance of this device. Furthermore there are some gaming reviews foot it on you've and so on. They are easy to find if you really look. Just do another search.
But for now here s why:
Tegra 3 is a quite performant soc for a mobile device. But it does have some issues.
First is the bad optimization by game developers. Mostly it's Gameloft. They then to ignore the fact that they should optize their games for different platforms to get a enjoyable gaming experiance. Had been worse. ATM most games are playable.
Next problem is that the graphics processors clock speed is firmly linked to the clock the CPU is running. This means when games do demands little CPU performance GPU will also clock down leading to lags. This has been improved with custom kernel, game updates due to tegra optimizations and custom kernels and ROMs.
Last but not least is that the CPU tends to be running in single core. All in all this service does have a lot of power... Mostly a lot of still unused power but I'm confident devs will go on and improve the situation even more than they already have.
For GTA just lower the graphic settings a bit or try rennovate gaming fix.
For now the only games that are not running for me as they should are GTA iii with some minor lagging, nova 3 playable since latest updates but not enjoyable. And last but not least real racing 3 with most of the time 35+ fps but many drops below 20.
For signal drops: maybe it's bad reception in your area?

Thanks for the answer, I did look around before asking this question but, all I was getting was answers that make no sense!
Soo, as far as I understood is the game developers plus the kernel but, that sounds like the device was not ready for the market yet htc released it!
One more question! do you think the phone is worth keeping?

no - send it to me
but you would be surprised what's possible if you use a different rom.
of course non-sense
the phone is good just HTC tends to cripple every device they release

yeah I know but I dont want to risk anything yet! :crying:
all the android phones I had were a HTC like the desire, desire z, sensation xe and for now the one x +, I have rooted all of them without a problem but, this phone is still under warranty I would rather wait for an update then root the phone:silly:

I don't think you understood what he said. The main point was, the GPU base clock runs at a set frequency directly related to the current clock speed of the CPU. So games like GTA that require little resources from the CPU, do not utilize the GPU to it's fullest. There are some custom kernels that allow the GPU to run at it's max speed regardless of CPU useage.

Well, I did and thats why I rooted my phone to Viperx+. I am uing the Viber elitekernel but I am having a problem in setting up the max cpu frequency to 1700, its always stuck on 1150 for some reasons and yeah I am using venom tweaks, any idea?

The max Clock Speed is 1600mhz when using all 4 cores, you can only get to 1700mhz when running on a single core. Do you have power saver enabled? That limits CPU frequency.

I found out that the game was not fully optimized for the tigra 3 chip, soo I rooted the phone and used Viperx+ 1.06 rom so I can have more control then the stock rom. Now i can do alot of things like set min/max cpu clocks speeds and soo much more, buttery life is much better now (thanks to SetCPU!!:victory but yeah I knew in the end (after going throw alot of reviews) that phone will use 1.7GHz with the 5th core only!
Is there a way I can run 4 cores at 1.6GHz then running 1 core at 1.7GHz or, if I just set max cpu to 1.6GHz, then I will run the 4 cores?
I am using elitekernel for venom team.
No, I dont use power saver anymore!:laugh:
