After reading the mainboard guide DDR400 for Athlon: A Comparison of 9 Motherboard (http://www.tomshardware.com/mainboard/02q4/021007/index.html) you can jump to the conclusion that the AMD Athlon XP processor, when used with DDR333 or DDR400, is the best processor for DivX encoding. In the Test Setup (http://www.tomshardware.com/mainboard/02q4/021007/kt400-14.html), it says:
mpeg4 encoding: Xmpeg 4.5, DivX 5.0.2 Pro (YV12), Compression/quality: Slowest, Data rate: 780 kbps, Format: 720*576 @ 25 fps, 150 MB VOB file, no audio.
These setting were used also in the mainboard guide Warp Speed with Rambus: Six Boards for PC1066 (http://www.tomshardware.com/mainboard/02q2/020624/index.html).
The results of the mpeg4 encoding show that the AMD Athlon XP 2200+ (1800 MHz) with 256 MB PC3200 reaches over 100 fps (109-117 fps with DDR400, 107-112 fps with DDR333; see http://www.tomshardware.com/mainboard/02q4/021007/kt400-16.html), while the Intel Pentium 4 2,5 GHz (2533/133 MHz) with 2*512 MB PC1066 or 512 MB PC4200 reaches only about 38 fps (38.32-39.09 fps; see http://www.tomshardware.com/mainboard/02q2/020624/i850e-19.html).
It's well known that at the same clockspeed the AMD Athlon XP proccesor delivers the most performance, but there still is a 733 MHz difference between Intel Pentium 4 2,5 GHz and AMD Athlon XP 2200+. Before congratulating AMD for the Athlon XP processor (personally, I think that the AMD Athlon XP is the best processor; it offers the best price/performance ratio), I want to know if this results are correct and how was this possible. If the results for the AMD Athlon XP 2200+ are expressed as time in seconds, then is impossible to compare the AMD Athlon XP 2200+ with Intel Pentium 4 2,5 GHz, since the duration and the framerate of the VOB file used in the test are not specificated. I hope the update of the mainboard guide DDR400 for Athlon: A Comparison of 9 Motherboard (with better results for Elitegroup L7VTA and the results for Abit AT7-MAX2) will clarify the matter of the mpeg4 encoding results.
