Comparative between gcc and icc (Intel's C/C++ Compiler): File: Pixar.One.Man.Band.2005.x264.mkv Duration: 4m 33s Res: 1280x536 Codec: x264 Command: [code]mplayer -benchmark Pixar.One.Man.Band.2005.x264.mkv -nosound -vo null[/code] MPlayer 1.0rc2-4.3.2, Ubuntu 8.10 RC, no optimization, gcc 4.3.2 (I suppose) BENCHMARKs: VC: [b]225.211s[/b] VO: 0.039s A: 0.000s Sys: 1.806s = [b]227.056s[/b] BENCHMARK%: VC: 99.1874% VO: 0.0171% A: 0.0000% Sys: 0.7955% = 100.0000% MPlayer dev-SVN-r27836, latest snapshot, default optimization for gcc 4.3.2 BENCHMARKs: VC: [b]213.311s[/b] VO: 0.039s A: 0.000s Sys: 1.906s = [b]215.256s[/b] BENCHMARK%: VC: 99.0965% VO: 0.0180% A: 0.0000% Sys: 0.8855% = 100.0000% MPlayer dev-SVN-r27836-10.1 latest snapshot, default optimization plus "-xL -ip", icc 10.1 BENCHMARKs: VC: [b]193.619s[/b] VO: 0.036s A: 0.000s Sys: 2.398s = [b]196.052s[/b] BENCHMARK%: VC: 98.7589% VO: 0.0182% A: 0.0000% Sys: 1.2229% = 100.0000% The lower time, the better, is the time needed to render the 273s video. Custom icc build is 8.5% faster than optimized gcc's build and 13.6% faster than Ubuntu's mplayer package. Anyway, latest mplayer snapshot is really unstable on my system, but you can get the idea ;) More info: [URL]http://macles.blogspot.com/2008/09/intel-cc-compiler-gcc-and-intel-atom.html[/URL] N6546R's icc compiled kernel: [URL]http://www.aspireoneuser.com/forum/viewtopic.php?f=28&t=5517[/URL] (Sorry my poor english)
