And until something comes out that will get that speed I will be happy to >stick with whatever is best at the time and not have to roast marshmallows on my >processors. :-)) What engine what he using? Some engines get REALLLLYYY low nodes/second, some get really high nodes/second. Want to see an example? Here is my CPU running Goliath Light v1.5. http://speedycpu.dyndns.org/fastgl.jpg 6,250kN/s, does this mean my PC is 2x faster than the 8 cpu Deep Junior box used in the Kasparov game? Nope. The point I'm trying to make is your aren't doing controlled tests. One PC gets 800kn/s in Shredder 7, the other gets 900kN/s in Deep Fritz, which is faster? The Shredder 7 PC, actually. See, you need to use the SAME engine, SAME position, SAME hash tables, etc. We've already done this. Mine got ~1720kn/s, Hyatt got ~2100, koibito got ~2400kn/s. You can take Deep Blue and put TSCP on it and then run Chesstiger 15 on a 486. When the 486 running 2000 nodes/second beats the pc doing 200 million, what are you going to say? Probably, "486 is my hero!!! I'm going to get a dual 486 and own everyone! HAHA" :P
