A math co-processor won't help you much in chess-programs since they don't use
floating point operations.

Take care to measure using the same chess-position ! The number of nodes per
second is strongly dependent on the positions to be evaluated.

It is indeed nice to benchmark though. I found my bro's 486DX2-66 to be approx.
10 times faster than my 386SX-20. Especially the 256K cache against 0K cache on
my 386 account for a tremendous speed-up. So it is not only a matter of CPU power.


GnuChess clearly indicates that a lot of nodes/sec does not necessarily lead to a
good chess program ! Try out Gnu 4 and you will notice that it is a lot 'slower'
than version 3. It plays a class stronger though !
