MP3 Encoding:
We used LAME MT for our audio encoding test - it's the multi-threaded 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 Play album to a 192kbps variable bit-rate MP3.

Time in Seconds (lower is better)
Again the Black Edition is a second off the Phenom 9600 ES's time which is virtually unnoticeable, but both still deliver lower performance than the AMD Athlon 64 X2 6400+.

Windows Media Encoder x64 Edition 9 comes as a free extra for 64-bit versions of Microsoft Windows. We encoded a 1440x880 Taxi 3 h264 trailer into 1280x720p VBR Windows Media Video file with CBR six channel audio in two passes, measuring the length of time it took for both.

Time in Seconds (lower is better)
Again the Black Edition is a second slower than the 9600 ES but, from looking at the 2.6GHz Phenom 9900 results, it should scale pretty well if you get a Black Edition that clocks better than both of ours.
