Scumbria, Check this out - These are SPECint2000 "Ratio" numbers. %Ath Faster/ Athlon -> 1.5GHz P4 Slower 1.2GHz DDR 1.2GHz SDR %DDR Faster gzip 557 0% 559 563 -1% vpr 299 11% 331 285 16% gcc 592 -33% 394 355 11% mcf 476 -51% 234 196 19% crafty 495 38% 683 678 1% parser 472 -14% 406 373 9% eon 785 34% 1053 1056 0% perlbmk 703 5% 735 720 2% gap 710 -31% 492 441 12% vortex 756 1% 764 731 5% bzip2 427 -10% 386 343 13% twolf 404 3% 418 360 16% In the tests where the AThlon w/DDR is noticeably faster than the Athlon w/SDR, the P4 is faster than the Athlon. But in tests where the gain from SDR to DDR is minimal the Athlon is faster than the P4 or the two are equal. Two anomalies are the "vpr" benchmark which the P4 just sucks at (the PIII is faster than the P4 in this test) and the "twolf" test. For SPECint - Tests that are heavily memory bandwidth dependent generally show the P4 as the superior processor. Tests that aren't memory bandwidth limited generally show the Athlon is the superior processor. Someone has been saying this for a while - The 850 is a great chipset, the P4 is a crappy processor.
