Other than Fowell's tests with Hiarcs? > I don't think this is true, either - my HIARCS tests only showed about a 39% advantage for G3 vs. the Pentium II at the same clock speed. (That does make the current 366 MHz iMacs faster than a 500 MHz Pentium, for HIARCS 7.0). The awkwardness with such testing is finding chess software where the same code is compiled for both Mac and PC. Crafty would be an obvious choice, but apparently the PC version has a several key routines coded in assembler (of course, one could compile Crafty for the PC without these routines, if one liked). One person to ask is Walter Ravenek - his "Arthur" program has competed in WMCCC on both platforms - maybe he has done some platform-platform benchmarks. I suspect that the "milage will vary" quite a bit from program to program - I found that to be the case in the speed ratio between chess programs executing on a 68040 vs. a PowerMac emulating a 68040 - the ratios were all over the map. -Richard
