Since FlaskMPEG is getting a little bit outdated, we've decided to include a new version benchmark for our MPEG to DivX encoding analysis, Xmpeg. We did however, utilize the same DivX 5.02 codec in each test, as well as the same video source MPEG file, an 18.6MB clip from the old time afternoon sit-com, Gomer Pyle.

First up, we'll show you the results from the FlaskMPEG run we performed.
The 2.8GHz Pentium 4, with either PC1066 or PC800 RDRAM, beats out the 2600+ by a comfortable margin, 12+% to be exact. However, at 2.53GHz, once again the Pentium 4 needs PC1066 RDRAM speeds to compete. Finally, the Athlon XP 2200+ brings up the rear but that was to be expected.
Here we've isolated our test to the only the top end test-beds from Intel and AMD. Xmpeg shows a larger spread between the P4 2.8GHz with PC1066 memory and the Athlon XP 2600+. There is almost a 24% differential between the high end P4 and AMD's finest. With a PC800 setup the 2.8GHz Pentium 4 still beats out the 2600+ by about 15% or so. Anyway you slice it the 2.8GHz P4 has a clear advantage versus a 2.133GHz AMD Athlon XP 2600+, when it comes to compressing and decompressing video streams.
