GPU S3 vs S2. On what depends video decoding? - Galaxy S II Q&A, Help & Troubleshooting

Hi
when I understood it in the right way, the S2 and S3 have the same GPU. (mali)
The only Difference is that the one from the S3 can run at 400Mhz.
But u can overclock the one from the S2 to 400 MHz too.
My question:
1.)If they run the GPU in the S3 @400 MHz is it then safe to overclock it in the S2 to 400MHz?
Or do they have a whole new cooling concept?
2.) On what depends the video decoding speed?
I can run h264 movies in 1080p at up to 14 MBit /s on my S2.
What bitrates is the S3 capable of?
Do they use CPU or GPU for hardware decoding?
Thx in advance

Generally hd video decoding are done via GPU, s3 is capable of playing any video at any format. the same stands for s2 , i havent found any videos incapable of playing.
No its not the same gpu.
sgs3 has double the power of sgs2 in gpu department due to clock speed and may be a nm shrink.
edit: looks like both are quadcore gpus

From what source you take that information?
My information:
S2 : DualCore + Mali 400 @ 266Mhz
S3 : QuadCore + Mali 400 @ 400Mhz
s3 is capable of playing any video at any format. the same stands for s2

I dont talk about the format.
The bitrate is the interesting thing. I can't play h264 videos with more than 14Mbit/s on my S2 @ an 1080p resolution

Does the galaxy s2 have mali-400mp4 the quad-core version of mali-400mp or some other one ?
it's really confusing
if it's a quad-core unit then how do i check that ?
And if possible could any of you put up a screen shot of gpu info from quadrant

improved Exynos CPU chip on a smaller die 32nm, (s2 45nm), its safe to use it at 400mhz but more heat is generated
Samsung mentioned its graphics performance is 50% higher than in the Galaxy S II, but this can easily be done by just upping the clock speed of the GPU to about 400MHz.

S2: 45 nm
S3: 32 nm
So they are different chips with different thermal profiles. Run the S3 at 400MHz and it is fine. Run the S2 at 400MHz and you get a lot of heat being generated.

The GPU can decode that without problems. Is your h264 video using AC3 audio? Test using a video with a standard mp3 audio track.

S3 more plastic feals cheap not my new Phone.. I am still use my sgs2.
Both are fast at playing Videos. I cant find any Video that can or will make any problem
I think i sell my s3
Sent from my GT-I9100 using xda premium

I transferred some videos recorded on my friend's s3 and played them on my phone and it plays fine but gets stuck at some points, misses some frames and then continues, audio goes on but video gets stuck. It worked fine if I forward to the point where it happens, then that part plays smoothly. from what I read, the S2 and S3 both record 1080 at 17 mbps so why is this happening? The files are stored on the internal SD and I played them using stock video player. I'm on siyah kernal also.
