When AMD's FX-6100 was benched testing PCMark 7 Video Transcoding under Windows 8, the score jumped to 7485 versus the score of 4047 under Windows 7 (increase of 75%). The total PCMark 7 score under Windows 8 was 4551 compared to 3995 under Windows 7 (superior score than many higher priced Intel CPUs). Has anyone else replicated this?

14% improvement overall, not to shabby.
PC Mark is something as Superpi, not real aplication
Futuremark paper has more info about specific benchmarks and they write this:
Video transcoding
-----------------
Video transcoding workloads transcode videos by changing the resolution, framerate and bitrate of the video. Video transcoding uses Fast Transcode feature found in Windows 7 Media Foundation.
Video downscaling workload (found in Entertainment and PCMark tests) source video is H.264 (1080p, 30fps, 12Mbps). The destination is H.264 (320x240, 30fps, 500kbps).
High quality video transcoding workload (found in Creativity test) source video is the same as with downscaling workload. The destination is H.264 (1080p, 24fps, 10Mbps).

So, it was not truly synthetic code from labs of Intel, AMD or Nvidia. Now developers can create or modify their apps to use MS media transcode library along with enhanced AMD FX utilization in Windows 8.
