The P4 is an integer dog, and >chess is dominated by integer/bit operations. The P4 apparently does not do well on Crafty or Fritz, AFAIK. The Crafty performance is probably explained by Crafty's propensity for mispredicted branches. Fritz, last I heard, was written in assembly. People often use tricks when programming in x86 assembly that do not work well on RISC-ier processors like the P4. IIRC, Fritz on the P6 was also a dog vs. the P5. The P4 does well enough at TSCP, and while that doesn't mean much in and of itself, I wouldn't be surprised if there were other chess programs that it performs well on. -Tom
