Sedat has a list of Axon Benchmark results here: http://www.geocities.com/sedatchess/hardware.html My problem is that I am not sure how those benchmarks corresponds to the speed with which real chess engines will run on different hardware. And I would like to know this so I can see how much I would benefit from a hardware upgrade :-) Take a look at these three benchmarks: AMD Athlon 64 FX-55 2.60 GHz (00:00:24.4 sec.) [3774488 pps.] PowX=11.759 AMD Athlon 64 3800+ 2.40 GHz (00:00:25.8 sec.) [3569671 pps.] PowX=11.121 AMD Athlon XP 2400+ 2.00 GHz (00:00:35.6 sec.) [2587008 pps.] PowX=8.060 I have the last one, with a PowX at 8000. I am a little surprised that the FX-55, according to Axon Benchmark, is less than 50% faster at calculating chess positions than my old low end computer. I think I bought my computer about 2 years ago, cheaply. So my question is, if I upgraded to an AMD Athlon 64 3800+ or such, would my Fruit only calculate about 40% more kn/s? In other words, do the Axon Benchmarks correspond linearly to performance in real chess engines? (If not, why! One issue I'm wondering about is 32 bit vs. 64 bit.) I hope that I can get some help comparing the performance of my fruit 2.2 to the performance on some faster computers. Here is Fruit 2.2 calculation of the starting position on my AMD Athlon XP 2400+, done in Arena. I used 256MB for hashtables, and made sure to clear them before starting calculation.

Thanks in advance.
