However, nothing leads me to believe that 2ghz == 2*1ghz. The problem is that the CPU goes faster, but memory hasn't improved at all in 10 years. DRAM chips still take just as long to dump/rewrite today as they did 10 years ago. And crafty needs a fair amount of memory bandwidth, or else a big cache, which the 21264 nicely provides... As far as speed goes. I have an 800mhz CuMine here... it does about 400K on the positions I use for testing... as it does on the crafty 'bench' command. The 21264 Tim had on ICC a couple of months back was definitely more than twice as fast as that number...
