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):
http://download3.dvdloc8.com/trailers/divxdigest/bourne_ultimatum_trailer.zip
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).
Full log: http://files.linuxsystems.it/temp/2011-09/vaapi-gm45-fulllog.txt
Hopefully one day vaapi on g45 will work properly and I will be finally
able to watch high bitrate movies on my laptop :|
Cheers,
Darkbasic
