[REQUEST] Tegra GPU OC....

Hey everyone...I tell ya, I sure am enjoying all these awesome custom roms and kernels. Great job to all the developers here, putting in the blood, sweat, and tears for the advancement of the community, thank you so much. One feature that I saw in a Xoom build was the GPU overclocked, and while I'm sure it won't interest everyone, and there is probably only little gain to be had from it, I would love to have the option to oc the CPU and the GPU for the highest performance possible...please. Well I think that covers it unless someone else shares my desire to see this feature. Thanks for all your work and consideration XDA and have a great day.

if ur CPU OC than GPU too

Apparently not so on the Motorola Xoom as there are two versions of Tiamat 1.4.4... with and without GPU OC. Tiamat 1.4.4 Full Throttle

oc-ing the gpu doesnt get you anything... gpu is default 200mhz 2d with 300mhz in 3d and it can be uped to 250mhz 2d and 400mhz 3d but it cant be software controlled and it will eat more power...
and no oc-ing the cpu doesn't oc the gpu, its a separate part of the tegra2 processor

Hey Thor, thanks for joining the conversation. Based on what youve seen so far, how well are the tegra GPU cores being utilized? Suffice to say I've pulled off insane desktop GPU overclocks that showed almost nill gain with drivers that werent mature in which the GPU cores werent being loaded past 50% . I realize that the tegra is a horse of a different color, but isnt it still affected by the specific driver optimizations, hence the THD enhancements? Just out of curiosity as I very much trust your experience. I am still interested in trying it with definitive comparisons to follow...well about as definitive as synthetic benchmarks can be anyway.
I just saw that you have a new beta... Yay. I cant wait to give it a whirl.

I have been over locked for a little while. Max I have done is 1506 but it tends to be slightly unstable. I run 1400 now and haven't had any issues. biggest difference I notice is home screen transitions load fast and don't lag and programs load much quicker. there doesnt seem to be any games that will push the CPU hard so I don't notice much of a difference there.

I've had 1600mhz going strong with no instability, benchmark after benchmark, the only issue I've had is the device shutting down when left alone for too long, but I consider that a useful standard function. Otherwise 1600 performance has been rock solid. I decided to take it upon myself to take this girl apart' clean the CPU off, remove the thermal pad, and apply some as5....though the chip didnt really run very hot to begin with. Now until I have the option to go for 1800mhz, I'd like to see where the max threshold is for cpu/gpu oc.

I have mine overclocked also at 1600.. Runs very stable at this speed and benchmarks not too bad:

Can only the 3D Clocks be altered without touching 2D? If yes can you make such a version of the ........... that "nobody" knows anything about?

Very nice quadrant score man, I used to score alot higher until I updated to stock 3.1+ updates. It seems like the higher my OS version number gets, the lower my synthetic performance gets overall.

Wow!
Umm, what rom do you guys run for this? I'm on rooted and CWMd stock 3.1 rom. Can't find a OC kernel for it. Only one I can find is for ASUS based roms. I prefer to keep stock rom if it's possible.

You should try richardtrip's kernel. His kernel is keep updating Very good performance and stability.

thats the kernel i am using o/c 1400 works very well. you can find it in the development thread.

Thanks! Works great. Do you feel the HoneyVillian rom runs faster with the v2.4 Kernel or about the same as stock Acer 3.1 HC rom with v2.4 Kernel?
So far I can keep stable at 1.5 after 2 hours of use. It's also slept for 30 mins and seems ok at that too.
Also what kind of Scaling do you guys use? Ondeman, Interactive? On my phone I use ondemand.

[Benchmark] Mobile Web Browser Comparison for Android

Hi Guys,
Like most of you I own a Iconia500 and I've tested a lot of ROM available on this forum. But hard to decide wich one to go with. the processing power is not all and the fluidity of the interface and the browsing are a lot more important to me.
So I've decided to test 6 Roms available on the forum with this:
Test protocol:
Fresh install
setcpu installed and locked to 1000Mhz
reboot and launch of the test
Here are the results:
Score 974 - ROM: Minimalist 3.1
Score 961 - ROM: Taboonay 1.0.6
Score 961 - ROM: Virtuous Thrive 1.0.1
Score 960 - ROM: HoneyVillain 1.04
Score 954 - ROM: Acer Stock Rom
Score 948 - ROM: Virtuous Picasso 1.1.0
Score 945 - ROM: Lightspeed 1.0
Score 940 - ROM: Virtuous Galaxy 1.0.5
Score 848 - ROM: Virtuous Xoom 1.1.2
I hope if helps,
Peace

Thanks, table updated.

Interesting tool, thanks for sharing. I get what you are after by comparing all ROMs at 1.0GHz, but don't forget that the more processing power you have (i.e. overclocking), the better your fluidity and browsing experience will be on any given ROM. I just ran a quick and dirty test (didn't reboot or anything) on my customized stock ROM with a 1.5GHz OC kernel with the "On Demand" governor (I used No-frills CPU control) and scored a 1222 with all bars being thicker than when running at 1.0GHz. Without overclocking I scored a 971. Even the stock kernel frequency tables are setup to be able to be OC'ed at 1.2GHz....so don't be afraid to goose that CPU a bit to get that tegra 2 performance you paid$ for

but OC = more power = less battery...

Yes, but only when you are using it...after the web page has loaded the cpu scales frequency back down if you are setup properly. It really depends on how you use your tablet, but I don't notice much difference at all in battery life the way I use mine (web browsing with flash, email, occasional movies and games). I still have to charge it every night either way after 6-8hrs of heavy use. The screen takes far more battery than anything else...live wallpaper would likely take more battery per charge cycle than an on demand [email protected] depending on how you use your tablet. IMHO, OC'ing to 1.2GHz is a no-brainer unless you are one of those guys on the road that needs to get every minute of life out of it. If that is what you need, then the iconia probably wasn't the best tablet to buy. After you OC, it's hard to go back as flash/web pages etc. load quite a bit faster as shown by the benchmark test.

I disagree. I didn't notice enough of a difference to warrant the loss in battery. I rarely even play any games and the games I play already run at 30 fps without OC so why the need to OC at all?

Battery drain would depend on which kernel and governor you used and how you use your tablet. Some kernel sources I have studied have their OC current set higher than is necessary. The one posted by Richard Trip/Roggin is very reasonable by default and you can even adjust uV by frequency to improve battery usage. The games you mention are likely using the tegra GPU/hardware, so the OC won't help you a bit there. I noticed the performance the most with flash loading on web pages. Give me a little more power on demand and I am a happy camper. If you really need that extra few minutes of battery, then I can understand. But, think about it...if you are browsing a lot, you can do more within a shorter period of time so it all comes out the same in the end.

I did a comparison @ same frequency to be a base for real comparison, you can overclock or use custom kernel, still, it is just a base

My reading speed isn't affected by the clockspeed of my tablet, so I'll still spend the same amount of time on a website..

When you are reading after it has loaded, the clock speed is the same as stock...it doesn't stay pegged at the OC speed all the time, the on-demand governor takes care of that for you

agreed but still the reaction is not instantaneous and some people just want to play with overclocking.
I found the benchmark tool interesting because it does not focus on pure force power but on user perception of the interface and after all I am a user

OP updated with a new ROM

Best rom for gaming?

I've been trying different Roms lately, such as cm10.1, slim bean, liquid smooth. They were all fine except liquid smooth. But I was just wondering in general, is there a ROM that enhances or makes gaming better on?

No. Your question is silly, it's like asking. What is the best operating system for gaming? Is it windows 7? Mac? Or Linux?
... What you're asking for are kernels, not roms. And there is no best rom or kernel. Just look around and try for yourself
Sent from my Nexus 4 using xda premium

As zephix mentioned, you should be looking at kernels, not roms, to improve gaming performance. You would want to look into kernels that overclock the GPU by default, or give you the option to overclock it yourself. Compare the different kernels out there, matrix, faux, motley,harsh, etc and see which one benefits the GPU the most.
For example the Matrix kernel has a GPU overclocked version that boost the gpu up to 487mhz. This should help improve game performance but will also negatively affect battery life when gaming.

Trinity kernel, its the BOOM

Trinity kernel forces gpu over clocking all the time though, with no option to set it back.

You can try the RasBeanJelly ROM + Trinity kernel combo. RasBean has new bionic patches while Trinity bumps up GPU. I'm running that right now. There was a nice jump in my Antutu score (20,000+), but we all know benchmark numbers mean nothing.
Like zephiK and Raider said: it's up to you to try out a bunch of different ROMs/kernels and see which ones you like best. Since I'm answering, I say check out RasBeanJelly and Trinity.

Faux' kernel gives me quite good 3D performance.
franco r53 has quite bad 3D performance for me. r61 seems to be really good, but somehow uses more battery while gaming, at least for me.

Every ROM is okay, I play games with vsync off and 128mhz CPU and they run good. Dead trigger, most wanted, temple run 2, and riptide are smooth. Games that aren't tolerable are basically not optimized and most likely lag on every device it can run on. Long story short, every ROM is apt, the GPU is a beast and isn't necessary for things out now. And HD YouTube even works in this mode.

All roms have bionic. Rom won't do anything to your game. Kernel probably won't either. Games on the stock nexus 4 run great. If it weren't for washed out colors I'd say kernels are a waste of time. But anyone saying that stock android on the nexus 4 is slow or unfit for gaming is a liar. Just stop worrying about this performance bs, enjoy your nexus.

[Q] Performance difference from different kernels on different roms

Hi,
I've noticed a huge performance difference between kernels and the roms they're used with.
For example:
I was using AOKP and Franco kernel and got around 20000 antutu points, I've switched to Carbon Rom (because of the build in pie control) and Franco kernel and only get around 13000 points, that's a huge difference.
As a test I've installed Matr1x-kenel on Carbon and get around 21000 points.
I really like Franco-kernel and all the tweaks it offers but don't like the huge drop in benchmarks, I know benchmarks are not a real representation of actual performance but it's still a big difference.
This also occurs in Quadrant and Geekbench.
So my question is why does this happen?
Aren't most roms supposed to be compatible with most kernels?
Thank you in advance.
Best regards.

I can't answer your question as to why that happens (no doubt someone else will) but you seriously should just stop bothering with benchmarks and use your own eyes and experiences as a measure of how good a kernel/ROM is. I doubt you could find a kernel which made the phone visibly slow or that affected usability so I don't see what your concern is tbh.

Thanks for your answer.
Yeah, I read that a lot on XDA, don't trust benchmarks...I understand that but they must have some meaning.
I mean, if not why do they exist or do people bother using them?
To be honest I don't really notice any real performance difference between most kernels I've tested.
Best regards

some roms include many optimizations(like skia/dalvik, krait optimizations, and others), while some dont. its not thekernel thats crapping out on you, its the rom.

your eyes can be decieved.. they can see whats happening in the ui for example, but you can not see the complex calculations that are being performed or how your cpu is really performing. you can have a slow device whos ui is quick.

OK, I can understand that not all roms are equal but why does changing the kernel have such a seamingly big impact?
If a rom is bad to begin with it should stay that way no matter what kernel you use with it.
Offcourse what do I know, I'm not a developer so my knowledge on the subject is limited.
I'm just trying to understand what's going on...

kernels vary too, and they impact greatly because they control just about everything in the phone, kinda like a brain. since the kernels themselves vary, one kernel might be better set up than another to deal with certain code from a certain rom. and then also, every phone reacts differently to each kernel(and roms to a point). thats why its recommended to try out different kernels, combos. only then you can find the perfect combo for you/your device. what works great for somebody, can be lousy for another.

OK, so if i understand correctly it boils down to this:
1. You can do benchmarks but don't base your opinion on just the benchmark scores.
2. Roms can vary greatly in optimizations and efficiency of coding.
3. Kernels can also vary greatly in optimizations and efficiency of coding.
4. There's no such thing as a "best for everyone rom/kernel combo".
5. Not all roms/kernels play equally nice with each other.
6. Play around with as many roms / kernels as possible and decide what works best for ME based on MY experience.
Thanks for the advice.
Best regards.

Its been well over a year since I ran any benchmark of any sort but I tested Franco and carbon because that's what I'm on and you mentioned low scores. I'm on Franco m3 with some tweaked settings and carbon nightly from 7-5. Antutu gave me 20636. I'm using stock CPU and GPU frequencies.

Maybe the nightly Carbon rom is more optimized?
I'm on Carbon 1.7 Stable and used Franco nightly 162 to test with.
When I benchmark I try to be as consistent as possible ie same temperature, performance governor, airplane mode etc.
I even cooled my Nexus in the freezer for some minutes to eliminate thermal throttling (yeah I know, watchout for condensation) but still got the same low scores.

It might be, I didn't do anything special. I left all my background apps running, didnt close anything in the recents, didn't cool the phone first. I just downloaded it and hit start. I use the interactive governor tweaked a bit, and I also tweaked the hotplug settings so it more readily onlines all 4 cores instead of waiting for some of the higher loads to trigger it.

Well, I had to try it myself so I did a factory reset, cleared system,data and dalvik, installed latest carbon nightly.
With stock kernel I almost reached 21000 points, with franco I barely get 17000 points.
Very strange...
edit:
I stand corrected, did a second benchmark and am now getting 20880 points...

are you benchmarking with your cpu speed benchmarked set as highest and lowest cpu speed? you should. if you dont put the same cpu speed as highest and lowest then itll scale up and down. if it scales, you dont actually know what speed its testing and it gives you inconsistamt scores. you want the cpu speed to be the same throughout the test.

When I benchmark I set the governor to performance, this should keep the cpu running at maximum speed without scaling unless I'm mistaking...

Gamer Rom

Make sure you set alucard kernel to the extreme performance or performance profile if you want better performance in gaming.

"great performance and Battery life ?" Performence or battery life! 5.1.1 CM with Alucard Kernel

if you get an alucard kernel in your rom then the raising the minimum clock speed to 810 khz on all four cores and the minimum for GPU speed to 200 khz it will help.
*gentle fair sleepers off
*arch power on
*CPU governors to ondemand or alucard with alucard hotplug
in developer option hardware overlays to off.
personally I think ktkernel was better with more options but you'd need to stick to AOSP 5.0 for that or lower

If he were to stick to older android versions (5.0 and lower) then he might aswell get KT kernel, which gives him the posibility of overclocking the CPU and GPU, something that is missing from the other kernels right now.

GPU overclocking isn't really stable, it actually takes away from the gaming experience.

How can increasing the GPU frequency, and therefor the performance, be bad?
If you overclock it too high of course it is unstable. But you should be able to take around 500 MHz easily.

I can't remember the steps you get in kt but I'm pretty sure the uppermost ones were next to unusable, 500 is only just above the standard speed.
the games are always going to have a fixed system requirement levels based on the hardware we have so there isn't that much to gain over optimisations for our roms I feel...
I always judge a rom based on how well it can play shadowgun deadzone. most untweakable kernel rom combos aren't so great fresh out of the box.

Well, I used KT kernel in the 5.0 days. I ran a gaming profile created by ktoonsez himself, which had GPU overclock, and ran stable all the way.
I usually judge a rom by how fast it opens the settings app. This presumes that the app was fully closed, otherwise it will just switch to it, wich is a lot faster than actually opening it. Also, animations are all off.
So, between the pressing of the icon and the actual opening of the app there will be a black screen (if animations are turned off). The longer you see that black screen, the slower the rom is.
