Go up one level in this thread


Thanks, though it will be a quite some time before I'm able to do that since I
still have to get the motherboard/sata hd/ram/case, and I'm not a rich man :)

I am curious how much l2 cache helps chess engines, though. Quite some time
after I put together my Xeon (512k l2 cache, 533MHz RAM), the newer versions of
the Xeons came out with 1MB cache and 800MHz RAM. From reading CCC for a few
years, I know the RAM speed doesn't help much, but does the cache help a lot?

And also, if I remember correctly, the even newer Xeons have support for the
same 64-bit instructions that the Opterons have. Has anyone in the Crafty camp
been able to try Crafty64 on these? (out of curiosity really, I'm going Opteron
all the way.)

Sorry for all the questions :)

Pete
