The AMD is faster on some simple instructions, possibly used in chess programs. There are also differences between the memory footprints of different chess programs which affect how well they fit in the different L1/L2 cache sizes of the processors. Hardly a simple comparison... :-) Anyway, a Xeon 450 will certainly outperform all our AMD 233s, except for price/performance. Bo Persson bop@malmo.mail.telia.com
