After the P4/1.5G got announced I made a "paper-based" comparison of a dual P3/1G with Dell's new 330 Workstation. The numbers are: P4/1.5G SpecINT2000 535 (one CPU) P3/1.0G SpecINT2000 418 (per CPU) (SpecINT2000 includes Crafty in its benchmark.) Those values are obtained using SIMD and SIMD 2. A feature that is not yet supported by VC++ 6SP4. Let us take Bob's suggested value of 1.7 for Crafty then the dual P3/1.0G offers a value of 710 (a p6/200 gets a value of 75). Since my old p6/200 calculates 100,000 nodes/sec, I expect a dual P3/1.0G to achive around 900,000 nodes/sec when using Crafty. Right? A dual P4/1.5G should be the first _dual_ CPU-based Intel system that reaches more than one mega-nodes when running Crafty. But if you can wait a couple of months, just buy a dual P4/1.5G or, maybe, a dual Itenium/1.5GHz........if you can wait, you'll probably never buy a system, because at the same time Dell ships your system, it's already outperformed by the next one in line.
