Corsair Dominator 9136C5D & 10000C5DF

Xvid Encoding:

We tested video encoding performance using VirtualDub-MPEG version 1.6.15 and a multithreaded version of the Xvid codec, along with the LAME MT MP3 encoder for encoding audio. We did a two-pass encode of a 15-minute 276MB digital TV recording with a target file size of 100MB.

We see almost 10 seconds improvement on the DFI as the memory bandwidth increases, but a slight CPU speed bump provides a three fold performance increase over any memory bandwidth increment alone.

MP3 Encoding:

We used LAME MT for our audio encoding test - it's the multithreaded version of the popular LAME MP3 encoder. We ran tests with both Intel's and Microsoft's compilers - naturally, the Intel compiler resulted in some performance increases on Intel's processors. We converted all 18 tracks from Moby's popular Play album to a 192kbps variable bit-rate MP3.

Performance isn't noticeably better than the XMS2-9136 and 50 percent of them are anomalously slower with an increase in memory speed.
