Results: WME9 x64, 7-Zip, and Far Cry 2
Windows Media Encoder 9 64 bit

With so many mobile devices handling high definition video, transcoding and encoding video is something most people actually do on their machines (though they might not actually realize what they are doing).  I take a 250 MB 1080p WMV video file and convert it to 480p (1 mbps VBR) with HD audio.  I then record the session time for the entire process.

AMD's December 2010 CPU Update: Phenom II X6 1100T Comes Calling - Processors 27

Intel has this one well in hand, but the 6 core AMD parts are not dramatically far behind.  Once the core count drops below 4, then we start to see some pretty hefty performance differences.

7-Zip

This free compression program comes with a benchmark to see how well a processor can theoretically zip up a program.  I set it for a 32 MB definition and tested 1, 2, 4, 6, and 8 threads.

AMD's December 2010 CPU Update: Phenom II X6 1100T Comes Calling - Processors 28

AMD seems to like this program, or vice versa.  The AMD processors outperform the i7 essentially across the board, except when they of course fall well behind in core counts.

Far Cry 2

While this is an older game, it does utilize quite a few cores for gameplay.  I used the Ranch Large demo, and utilized two sets of quality settings.  The regular quality ran at 1024×768 with High presets, no AA and AF.  The second runs at 1600×1200 with Ultra presets, no AA and AF.

Some pretty fascinating results here.  The program does like more cores, and the Intel processor takes first prize here.  But looking at the minimum frame rates, AMD is a whole lot smoother.  While watching the demo roll past, the Intel machine would chug quite often, as exhibited by the very low minimum frame rate.  The AMD processors seem to do a lot better.  We also see a pretty hefty difference between the X2 565 and the X3 455, and even though the X3 is 100 Mhz slower and does not feature any L3 cache, it has a much higher average framerate due to its extra core.  Once quality settings get increased, we see a smaller difference in average framerates between the processors represented.
