DivX converter is pretty much single-threaded but still QX9650 is able to encode slightly faster. Having more cores certainly helps speed things up in H.264 Encoder and VirtualDub apps.

Updated : We re-ran VirtualDub 1.7.6.1 again with Experimental SSE4 full search enabled with the QX9650 and SSE2 for the rest of the processors. Now we are able to observe quite a boost  when we compress a MPEG file into higher compression DivX using VirtualDub 1.7.6 w/ DivX 6.7 codec. Certainly, the 2 new SSE4 instructions, PHMINPOSUW and MPSADBW on QX9650 speed up the whole encoding process. We will re-examine the applications again in greater details and hopefully we can get to test out upcoming TMPEGnc Xpress 4 that supports SSE4 on next week. More SSE4 supported applications to come along next year.
