Xvid Encoding:
We tested video encoding performance using VirtualDub-MPEG version 1.6.15 and a multi-threaded 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.

Time in Seconds (lower is better)
The Kingston is consistently slightly slower than everything else, and has a good six seconds between it at native 1200MHz and the equivalent overclocked Corsair PC2-9136. Even at 800MHz low latency, there's some eight seconds difference. This may seem a lot but it's a field with a tight spread still.
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 popular Play album to a 192kbps variable bit-rate MP3.

Time in Seconds (lower is better)
With the Intel compiler the Kingston is at most a second or two slower, but there's really nothing in it across the entire MP3 encoding tests. Yet again, at the stock 1200MHz speed the Kingston is a slower than the rest of the field, however.

Time in Seconds (lower is better)
The MP3 decoding tests are again a mixed bag. At 800MHz the Kingston is a full 14 and 23 percent slower, than the competition, but at a native 1200Mhz and overclocked 1232MHz the Kingston is faster than the equivalent Corsair's.
