Overclock GPU? - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

Is there currently a method to overclock the GPU? I see in the Exynos 4212 it is clocked to 400mhz vs the 266mhz which is a pretty dramatic increase. I understand that the 4212 is on a smaller fabrication size but I have also read that it can be done on the Galaxy S II with the same CPU. I ask this because I find the tablet to be particularly laggy when simply just scrolling around and swiping side to side on the home screen.

Tegrak can help you do that (Paying app that you can find in Google market)
That being said I doubt it will improve much your scrolling. Some Build.prop mod are actually helpful
If you want to stay with Samsung's base ROM and not go the CM road, I would flash SkyHigh ROM. You will see an amazing change in scrolling speed and general responsiveness of your device

[INFO] Sensation NEW Benchmark Scores

Hey I thought it would be cool to just have a seperate thread for this so people can stop asking so much al throughout the other threads.
I've seen 2342 so far on the released version compared to the model in prerelease which was 1300 score. Thats a very fast speed.
Post yall quadrant scores here.
Remember also that all who view this the sensation has a qhd screen.
Makes a difference.

And as I've been reading on other topics there might be a incompatibility problem due to two cores. It's new chipset and has different architecture etc. Lets give it some time.

People have been saying that the sensation is getting low scores because benchmark programs are not designed to test both cores.
I find that most people are throwing around nothing but assumptions for reasons i really cannot understand. Do you know for a fact whether those benchmark programs are optimized only for one core, or is your enthusiasm for the sensation subconsciously pushing you to say that ?????????????
The author of smartbench has posted a comment on another thread in this forum that one of the main reasons smartbench 2010 was pulled out and smartbench 2011 released was testing dual core phones. he added that he does not know why is the sensation getting such low scores as compared to other dual core phone, but will investigate and come back.
So irrespective of my personal preference to HTC phones, and if smartbench author cannot find a bug in his smartbench 2011 leading to low scores on sensation, i have to say that the sensation CPU does not seem to be at the same performance level as other dual core phones

The overall UI is pretty fast, but web browsing... not as clear cut as i would have expected from the specs, the Ram used by Sense seems to be the problem.
I got a score of 2306 in quadrant advanced, only did one run as waiting to root before going further :S

Sam, I saw your youtube video of browser performance for Sensation. That flash pinch-zoom thing was horrible. Was this consistent across all websites?
I would have expected better. I feel most of the guys might know about this, rest of us who were unaware, check out Sam's youtube channel. Keep up the good work mate!
I just digged more into the CPU in QSD8x60 It seems to be the same scorpion cpu that ships in the MT4G. According to my data the exynos CPU is 16% faster than the qsd8x60 at the same clock speed ( 2.5 DMIPS vs 2.1 DMIPS ) being architecturally different as exynos is cortex a9 and the other one is Custom Cortex A8 so the lower score. The Sensation Smartbench productivity score is exactly 2.4x that of a stock mt4g. Other things that are affecting smartbench is the Memory Score, I/O of Sensation is around 0.5x that of GS2 and 2d score is around 0.25 x (lower due to more resolution) of that of GS2 maybe due to the fact GSII has hardware acceleration. In real day use Memory, I/O arent going to be affecting stuff much. The CPU on Exynos is faster, GSII has hardware acceleration and I/O and Memory score on the GSII are much higher. When it comes to graphics at the same resolution they are both on the same speed when on the same resolution but difference comes due to sensations qHD display. So for the performance in day to day life the Sensation isn't gonna be much of a difference over Desire HD or the GSII when executing single threaded apps which are 99% apps on Android market and like with most >1ghz CPU you wont experience lag and for the graphics they are gonna be much much faster and better. The Linpack score which tells you the speed of execution of apps written in Java which most Android apps are it is going to be same as GSII, No difference. When executing Native Apps GSII will be faster but when it comes to Native Apps, Most of the Native Apps are games which depend more on the gpu so here too both are same. When it comes to Multimedia Sensation is faster than GSII as it has a 128bit pipeline but both are capable of decoding/encoding 1080p at 30fps and no one is gonna go beyond that. It will only be different when using anything that is on Neon.
To sum it up
Both Phones are extremely powerful and perform better than each other in different scenarios. They are at a point where the difference are minor when coming to performance. To buy a device it entirely depends on your choice as IMO they are both no.1 at the android device table right now. You wont be disappointed by any of those
Do you have the device yet?

My g2x on froyo is higher than the sensation.
But I bet the sensation is just plain more reliable

No but i have the datasheet of the processor in it and i know the scores its getting in benchmarks, these scores can be calculated even via the datasheet.
About G2X Tegra2 is plain sucky when it comes to dual core and it is slowest of the bunch. The Java Apps dont perform well and that is what android is based on. Native Apps are mostly games and tegra 2 is good but Sensation is better on both

They doesn't quite make sense as the mytouch is a stock 1.4 chip MSM8255 the g2 and mytouch are basically the same processors underclocked to 1ghz. The sensation is a stock 1.5 dual core capable of 2.6 ghz overclock The score the sensation getting is the same the score my mytouch was getting out of the box. That indicates that the other processor isn't quite doing anything. At its not the same as a mytouch. The chip in the sensation is MSM8660 Dual-Core SoC with Adreno 220 GPU. Equivalent to the one with HTC evo 3d. QSD8x60 dual core hasn't even been introduced yet.

it doesn't seem like most of the people hear understand the async tech used in the new qualcomm chip... there is soo much into it that i myself wonder if it is worth it to have a dual core phone at this point as much apps wont stress the first core enough to push the second core to a clock speed close to 1.2 ghz.. yes i do like the sync speeds of the sgs2 but still i think its over kill... to try to put it in lamens terms the sgs2 cores will be at 1.2 ghz in use and what ever mhz at rest while the sensation could have 1 core at a clock speed of 1.2ghz and the other at what ever to relieve the stress be it 3 4 5 6 hundred mhz so until we really get programs to mimic whats needed to make the second core jump to 1.2 ghz we will always wonder about benchmarks which are useless to me

Nope I understand I said this early about lower benchmarks. I don't care about them and I do understand the qsd chip isn't similar to the msm Chipset. Similar processors would be g2 and the mytouch 4g as they have the exact same architecture. The mytouch architecture though similar being a a8 should be vastly different

I said "there might be". That doesn't mean there is. Most of us don't have this phone so we're making guesses of course.
Early anandtech benchmarks say (don't want links again just search yourself) this chipset at default 1.5 ghz is better than other dual cores. 0.3 Ghz downclock doesn't effect that much. So we're suspicious that there might be incompability problem. Because chipset is new, phone is new etc. And that author doesn't have Sensation too. Then I said "lets wait". Is that ok for you?

sensation performance / aSMP info needed please

Hi,
i recently return my samsung (4th time) galaxy s2 becouse of various defects , i been looking at the sensation however i have a few questions , firstly for all its issues i like how fast and responsive the galaxay was however when i tryed the sensation i noticed its not as smooth as the galaxy or that much smoother then the desire hd.
One possible reason for this i noticed was that the sensation uses a asmp cpu , which seems a bit cheeky to me. I mean im buying a dual core phone so i would like both cores to work at the same time as opposed to one working then the second kicking in when the first is loaded. From what ive read ics should have better support for this setup , so i was curious does anyone think we will see that much of a difference bearing in mind the sensation is asmp.
I notice there`s a lot of talented devs from the desire development and hd which is encouraging so i was hoping to learn from various users how much of a performance increase there seeing in custom roms ie is the browser jerky like stock ??
Appreciate any / all feedback thank you
I'm interested in some more more info on this topic as well.....
Sent from my Sensation using xda premium
Read up!
ok so aSMP doesn't really work in the method of core 0 gets loaded then core 1 kicks in, thats way off.
basically SMP cpus like Tegra and Samsung's both cores run at the same speed, so core 1 follows core 0. This doesn't mean that core 1 is actually processing anything. In most cases due to gingerbread the phone is still mainly running on one core unless the app supports multicore.
aSMP allows the cores to run completely independent. This is great for battery life. Core 0 can do things like play games and stuff at full speed while core 1 handles background data.
so playing angry birds while syncing photos on flickr:
core 0 could be running at full 1.5Ghz
core 1 could be running at 500Mhz just do handle the syncing
This is basically the idea. We will get better support with ICS for full and proper support for multiple cores and the kernels will only get better as devs learn.

Hi,
Thank you for you detailed reply ive been following the thread you posted which is what led me to posting question here , i obviously misunderstood what was being said. That being said im no expert but if i buy a dual core phone id rather have both cores committed to one task like pc ... this is one of the things thats making me hold back on sensation. Althougth its a great phone with great ui and fantastic potential with future updates and dev support to the touch at present the galaxy s2 just seems smoother with the way its doing thing.
As i say thou im not expert i can appreciate theres other factor to take into account such as kernal etc, im just going with hands on usage and trying to evaluate the future potential for both devices before making a decision to which i should choose

The sensation's CPU works in a much more power efficient way, while still offering the speed of any other dual core CPU. It allows different clock speeds for different cores so applications using only a single core will be able to clock it differently to those using the other in the background. Computers, especially laptops work in a similar way, as there is a need for power efficiency. Realistically the Galaxy SII runs smoother due to it running a much less resource hungry skin on top of android, but both the CPU of the sensation and the Galaxy SII are both of a similar calibre, so it is very difficult to say which is better.
again thanks for the reply , defintly understand how this asmp buisness works more now which has given me some stuff to think about

Neither architecture, SMP or aSMP, will commit both cores to one task unless the app is multithreaded and it currently needs the use of both cores. This is the same way that multicore pc's operate. That's why when quad core CPU's first came out people said that they didn't feel any faster than comparable dual core chips - most existing apps at that time were written for single or dual threaded use so the third and fourth cores largely sat unused. The pc doesn't just force the use of the extra cores just because they are there (regardless of how they scale, aSMP or SMP).

Also the new firmware has made it smoother due to extra optimisations. Web browser is not as good as the galaxy S 2 due that being GPU accelerated. Power wise the Sensation you will get somewhat more out of your battery life wise.

If you look at my thread and see the post:
MSM8x60:
Adreno 220 GPU
2x Cortex A8 Based Cores
512KB L2 Cache
45nm
upto 333Mhz LPDDR2
Exynos 4210:
Mali 400 GPU
2x Cortex A9 Based Cores
1MB L2 Cache
45nm
support for LPDDR2/DDR3
Tegra 2:
ULP Geforce GPU
2x Cortex A9 Based Cores
1MB L2 Cache
40nm
support for 600Mhz LPDDR2
So the biggest thing is is that the Exynos is based on a new core micro-arch then the Snapdragon 2, also it has the ability to support DDR3 memory. To go into more detail about ARM Cortex.
Items that A8 and A9 have in common:
Jazelle RCT for JIT Compilation
Neon SIMD Instruction Set (Optional)
Thumb2 Instruction set
VFPv3 Floating Point Unit (Optional)
Cortex A8:
Superscalar Dual-Issue Micro-Arch
2.0 DMIPS/Mhz
Cortex A9:
Out-Of-Order Superscalar Micro-Arch
2.5 DMIPS/Mhz
Jazelle DBX for Java Execution
Dual-Core Processing Built In
The SGSII has a new generation architecture as so does the Tegra

Dual Core Dual Channel but only running on 1 core??

Howdy everyone,
i happened to come across an app on the market called CPU Gauge and this demonstrates to you exactly what each core on your phone is doing at all times, even in your notification bar at all times. Now i have noticed no matter what i do there only ever seems to be 1 core running which is pretty pants i reckon. how can i enable it to run dual cores all of the time? i dont understand it personally, why have a dual channel architecture if its hardly ever used? and surely it having to decide whether to use one core over two and to send data down both channels or just the one is probably a reason why we get lag? i am probably completely wrong but id rather the cpus always be on and drain battery if it improves overall performance

Though a mod will move this thread please post questions in the general section this is for development purposes only..
But if what you say is true i will have to look into this. What rom are you currently running?
Just a rooted/overclocked LG stock gingerbread rom.
For me it shows 2 Cores working ,but second is ON only when needed (as it should be) So its OK. Lags are because of poor ram managment on LG software, I recommend Rushdroid ROM.
What I know, Android 2.3 and below does not provide a support for multi cores. However, ICS does support it. So, I think the phone will run much better when the ICS update comes.

nope. thasts only an urban legend But it can improve performance at some points, but I would be rather sceptic. Custom roms must be always better (what they are doing making software, making it slower on purpose? go Samsung way and hire cm team members)
In games it uses both cores but im dissapointed that when testing swapping between different apps and web browsing seemed to all be using just the one core, and that was with lags inbetween swapping from for instance gallery to browser. I love this phone great specs but it annoys me more and more to think LG really did have no clue when it came down to putting it all into action. is there any way to have 2 cores on at all times or atleast change the values that decide when to use second core/channel.
If anything it makes for an interesting discussion

It has a partial support, not 100%, and the proof is that all dual core phones which received ICD update, got a huge improvement in the performance, as their users said.

The processor works as it should be, all cores when needed. Check System Panel app. Ram is the issue here. On stock it will be always laggy. On rushdroid and samba there is good ram management. Almost 250mb for the user. On stock i doubt if there is 130mb free available.
@up: there is no evidence that GB supports 1 core only and ICS multiple cores. A better performance on ICS can be due to the bigger optimizations, and hw support (that can be buggy) like gpu enabled scrolling etc.
But Ive heard that ics supports fully multicores, and that is an urban legend for me (no evidence) Ics can be just more optimized than gingerbread (and more like honeycomb which was quite fast)

you are correct cores are working as they should be not a problem here at... Gingerbread supports multicore and does use the cpu to the max when needed, you don't need to run both your cores all the time if that was the case you would need to charge your phone every 3 hours....
The issue with our optimus 3d is it needs ram tweaks to keep it smooth, 512mb ram is good i am not complaining because it's dual channel and so on so the ram speed is amazing just to free up ram we have tweaks...
Also the cpu is used to the max when needed, when you make a call you do not need both cores working at the same time that would be pointless. But when you play games, browse the net and bench your device all cores are used at the same time...
if you want to try it (see the difference) with both cores enabled ,(and cpu speed at max) try system tuner app , in cpu setting put governor to "performance" the first core will go to max speed , then go to active tweak and there is an option to force all cpu on , try it , it will be hard for the battery... when you put governor back to hotplug , the second core will return on demand (on/off) . if you want to do it again after you have to redo all step and turn the force all cpu on off and on again...
i'm on v21D on rushdroid 3.6.3. Both cores show up as working. 1 core ususally hits 1.4ghz and 2nd one upto 1ghz during regular processing. Great app btw tnx for letting us know

Its not neccessary to use dual core all the times ,using dual core for small task degrade the performance that increasing. Since our phone have dual memory the cache plays an important role in deciding which core should be used.

Overclocking Question

hi all,
i want to root and overclock my TF300T
for the overclocking:
-Can i use setcpu ? What other tool is good for OC ?
- Do i need a Costum ROM for overclocking to 1.5Ghz (MAX!)
-Will the performance be a lot better ? or just better ? or no diffrence ?
-What is the highest possible OC ?
Thank you
If you are on ICS you can over clock to 1.5 no problem. I don't know about Setcpu on ICS, but I do know EzOverclock works.
If you upgraded to Jellybean, I don't know of anyway to overclock as of yet. EzOverclock won't work on Jellybean and reportedly causes boot loops. I tried setcpu on my Jellybean Tf300 and found the CPU to be maxed at 1.3.

ok thank you, can i look somewhere to find out when EzOverclock is compatible with JB ?
Thank you

It really depends on how you use the tablet, and where your bottleneck is. My feel is that I/O is the biggest bottleneck on the ASUS pads and the effects are felt across the board. I believe ASUS is working on a fix, though. Fingers crossed.
I/O notwithstanding, day-to-day tasks like email and web browsing don't need a 1 Ghz. Even video playback won't be affected by the difference between 1.2 Ghz (the ASUS performance mode) and 1.5 Ghz (typical max OC). Rendering graphics, I'm not sure how much is offloaded to the GPU, so games or graphic heavy applications may be where you'll see the most gains.
EZoverclock don't work on JB it will keeps restarting your tablet when EZoverclock starts.
And other apps work but can only be set to 1.3 so no overclock on JB with this kernel.
I think in graphically intense applications, such as games, would offer the most notable difference even with gpu offloading since not all instructions are graphics related. That being said just know that battery life will take a hit.
Remember...... as of now EzOverclock will not work in Jellybean.....

Overclocking/undervolting the TF700 gpu

Dear XDA people,
Im currently working with Max's V4 RC2 kernel in combination with Cromi-X 4.6.9 (still need to update to the latest), which gives me a pretty smooth working tablet.
Now, im running the cpu at 1900mhz, 1225mV (still testing if i can go lower), and I can adjust speed and voltage nicely with Trickster Mod.
But, I would wan't to crank up the gpu speed (which is currently 666mhz I think?) and have the same "options/settings" available to do so. For example, a rom limitation of 750/800mhz on the gpu, with a variation of voltages to choose from. This way I can get as much gpu power as possible, since i find gaming on the tf700 pretty disappointing in terms of performance (of course a lot of games are not optimized for tegra).
Do you guys know what would be the best possible solution to overclock/adjust the gpu speed+voltage?
Thanks!

I think 666mhz GPU setting is probably reserved for Satans minions. At the moment the only way to control GPU speed is by adjusting the voltage. This is easiest using hunds kernel (3.1 if you have problems with 3.2) and his app. Together, you can crank the GPU all the way up to 775MHz and fry some eggs on the back of your TF700 and waiting for it to go into nuclear meltdown.
I know the gpu runs hot, thats why I want to see what speeds can be achieved with limited voltage. So you‘re saying the only way to change gpu speed is by setting a higher voltage for it? Why is that exactly?

You've posted this in the wrong forum, so it will be deleted, in the mean time there is really no reason to use 1900mhz even less so while gaming. 1700mhz at max (it can go higher but you wont see much change/ if at all in benchmarks/ games but u'll see the difference in battery life)
As for gpu i run 750 mhz but again the difference between 650 - 750 mhz is hardly noticeable, gaming performance isn't great on the tf700, the tf300t doesn't look as good but its noticeably smoother with 3d
Moral of the story the tegra 3 gpu isn't powerful enough for 1920x1200 the tegra 4 wont be much better, the tegra 5 is the interesting one

Yes, that's what I'm saying. Unless you want to learn to create kernels and do all the magical voodoo these wizards do to bring us OC kernels!

I have no idea, been wondering that myself. I even posted the question somewhere about a week ago, but no one enlightened me. I really reccomend using hunds kernel and app though. There is a "gaming" option in his app that works very well, good speed without the ominous red glow of molten metal on your TF700's back panel.

Are you saying increasing gpu voltage will subsequently increase gpu frequency? (i have no idea how it works, ive never bothered to look into it but now im interested) _that or Hunds will know but im guessing if thats the case freq and voltage must be linked in a voltage table but i would have thought freq could be changed independently to voltage

I know the tf700 isnt much of a gaming tablet unfortunately, but then again, why not setting it up so that it runs games as smooth as the hardware will allow ? Every small improvement is an improvement if you ask me.
For 750mhz gpu, what kernel are you using?

I'm using hundsbuahs latest kernel, the problem with tegra CPUs is thermal throttling, it starts around 72c on a lot of devices (not sure about the tf700) at 1900 you could find worse gaming performance than a lower cpu / GPU clock speed. Its completely up to you, hundsbuahs kernels give users a lot of flexibility as they can push the devices to the limit, I like _that's kernels personally they suited to my usage (what ever that means)
