It is a 21264 processor at 667 mhz (this is not the fastest clock they expect for this cpu). The bench figure was 850K nodes per second (one cpu). The 750mhz machine (which can be bought now or very soon) will do 1M nps at least. And then you can factor in multiple cpus. :) But yes, 64 bits is a _big_ help...
