It would appear that my 8400 GS with the G98 core, VP3 and Feature set B support should be much better than my 8600 GTS.
(As I contributed to the page and it says - imo - the exact opposite: Note the unsupported widths for H264 decoding: )
Why do you think so? Typical CPU's tend to be much faster than any GPU - at least for NVIDIA VDPAU bit-stream decoding.
Otoh, on my Pentium III 500 (which - I hope we agree - is not a typical CPU these days), a Geforce 8400 GS is much faster than a Geforce 9400 GS when it comes to decoding MPEG1/2 or VC1.
