Benchmarks on video encoding P4 vs A64 Please

[sportster64]

I'm looking at upgrading my P4 1.5 to an Athlon A64 3000+ either 754 or 939 socket. BUT I've seen reference to the P4 prescott being faster at doing one of the main things I use my comp for - digital video encoding to mpeg2. Can someone tell me how much better the p4 does this as opposed to the a64 ? Possibly point me to some benchmarks ? Thanks in Advance.

either gonan do it way faster than your p4 1.5.

I think the A64 is faster at mpeg-2 encoding but hte P4 is better at DivX.... I may have those backwards.... however I would figure that going for the A64 would be your best bet either way

Doing video encoding in 32 bit single-thread code under Linux/Mplayer, my AMD64 3400+ Newcastle is about 10-20% faster than my P4 2.8C (Northwood). That applies to several different encoders (mpeg4 and motion jpeg).

Both MPlayers have been compiled on the final platform, so could choose freely between MMX, SSE, 3Dnow. I didn't look what was actually used in the end.

In 64 bit code things plummet to about 60% of that performance, clearly the encoders are not very smart here and probably blow the first-level cache due to bigger pointers of Integers.

Here's raw data. "vid" is mpeg2, "vie" is motion jpeg. "h" and "b" is high quality, the numbers are compression levels, the higher the smaller the file.
