[Intel-gfx] VAAPI GM45 benchmarks

[Niccolò Belli]

Hi,
I did some benchmarks on my Samsung X360 laptop.

The cpu:
model name      : Intel(R) Core(TM)2 Duo CPU     U9400  @ 1.40GHz
stepping        : 6
cpu MHz         : 1401.000

The sample video (89 seconds, 80 MB):

Video Type: 1920×816 (1080p), 23.967 FPS, CE-Baseline profile (PS3 and 
Xbox 360 compatible)


Multi threaded decoding:

mplayer2 -vc ffh264 -lavdopts threads=3 -benchmark -nosound <file>

Time elapsed: 28.313s



Single threaded decoding:

mplayer2 -vc ffh264 -lavdopts threads=1 -benchmark -nosound <file>

Time elapsed: 38.774s



vaapi (kwin desktop effects ON):

mplayer -vo vaapi -va vaapi -benchmark <file>

Time elapsed: 205.888s



vaapi (kwin desktop effects OFF):

mplayer -vo vaapi -va vaapi -benchmark <file>

Time elapsed: 198.548s




CPU USAGE:

First one from left is multithreaded, second one is single threaded, 
third is vaapi with kwin on and last one is vaapi with kwin off.
Note that even when it quits mplayer at the end of the vaapi tests it 
keeps using the cpu for some time (you can see it in the screenshot).

Hopefully one day vaapi on g45 will work properly and I will be finally 
able to watch high bitrate movies on my laptop :|
