Depending on who you believe, the dual AMD will run somewhere between 1.4 and 1.7 times as fast as a single cpu. So that dual 1000 now looks like a single 1400 to 1700 machine. But you aren't home yet. A parallel search is going to be somewhere around 1.7X efficient rather than 2X, due to extra nodes searched, so that dual 1000 will be slower. Let's solve this completely: 2 * 1000 * 1.7/2.0 * 1.7/2.0 (giving AMD the benefit of assuming the dual is 1.7x faster overall which I have not seen from numbers posted here) and you get: 1445mhz. Take the single cpu you mentioned. :)
