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): =

ip

Video Type: 1920=D7816 (1080p), 23.967 FPS, CE-Baseline profile (PS3 and =

Xbox 360 compatible)


Multi threaded decoding:

mplayer2 -vc ffh264 -lavdopts threads=3D3 -benchmark -nosound <file>

Time elapsed: 28.313s



Single threaded decoding:

mplayer2 -vc ffh264 -lavdopts threads=3D1 -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
