Audio/Video Encoding
MusicMatch Jukebox 7.10
DivX 5.2.1 with AutoGK
Armed with the DivX 5.2.1 and the AutoGK, we took all of the processors to task at encoding a chapter out of "Pirates of the Caribbean". We set AutoGK to give us 75% quality of the original DVD rip and did not encode audio. 
XviD with AutoGK
Another very popular codec is the XviD codec, and thus, we measured encoding performance using it instead of DivX for this next test. The rest of the variables remained the same as the DivX test. 
Windows Media Encoder 9
To finish up our look at Video Encoding performance, we have two tests, both involving Windows Media Encoder 9. The first test is WorldBench 5's WMV9 encoding test.

#9, I found it a little odd as well, but keep in mind that, not too long ago, Intel was still winning multimedia and 3d rendering benches on a regular basis with Northwood and Prescott. This might explain why Intel won narrow victories in some of the in-house multitasking benchmarks.What is clear is that the X2 is the superior processor when it comes to running lone multithreaded applications.
The X2 is useful for anyone, while the Pentium D will only shine for people with distinctive usage patterns. Too bad the X2 costs so much.

#9 every REAL WORLD AMD wins. I don't even look at synthetics or contrived benches so someone else maybe tells you if Intel won one.:) They tend to do really well in those.Zebo - Monday, May 9, 2005 - link
Total domination too bad I can't get one now!!!Anand what memory timings and CMD rate used in this review?

Is overclocking the same with a dual core cpu?reactor - Monday, May 9, 2005 - link
good article, cant wait to see how yonah stacks up so i can make a decision on what to get.btw the graphs all say intel pentium D 840, instead of 640.

Is it just me, or did AMD win in EVERY benchmark program? Simply amazing.Still, it surprises me to see intel push ahead on multitasking by a tad.

I hate the price of admission!anandtechrocks - Monday, May 9, 2005 - link
Amazing preformance, but half a G is really pushing it for a processor...Capt Caveman - Monday, May 9, 2005 - link
I hate that we have to wait til Q3/Q4.Brian23 - Monday, May 9, 2005 - link
While I'm very impressed by this IC, I hate paper launches.
