I personally tested MANY different computer systems with optimized Crafty binaries. Incase you're wondering the speed difference follows over to other chess programs as well. Such as a Celeron-1GHz being faster than a P4-1.5GHz in Crafty and, say, Deep Junior. Here is a graph of my results from the testing I've done: http://speedycpu.dyndns.org/crafty/craftybench4.jpg Each CPU used a binary optimized specifically for that CPU. An AthlonXP had a partially AthlonXP optimized Crafty binary (Matt Taylor is working on even better optimizations). Pentium4 used a binary optimized Pentium 4's. Pentium 3's used P3 binaries, etc. I made a large effort to make the fastest binaries and to produce the fastest results possible out of all of the machines. So far I think the Pentium 4 is a waste. It's slower, runs hotter and is much more expensive. Why bother? For those of you that say AMD is unstable I highly recommend you using something other than a $50 motherboard or a cheapo stick of ram. It's not AMD's fault if the board/ram/etc is of poor quality. Don't blame them. I've been using AMD cpus since the 486 days and have NEVER had any stability problems when the chip was coupled with quality components.
