Subject: piece-lists versus bitboards on 64-bit-systems

Author: F. Reul

Hello,
a few weeks ago, I read an article in "ct-magazin" about the 64-bit-world. The
benchmark-test "186.crafty" promises 20 percent speed-increase with the new
64-bit-compilers of Intel and Microsoft with Windows x64 on a 64-bit-system.

My question, can some programmers confirm these results, are there any articles
online to read about this, and is a speed-increase of bitboard-engines more
than 30 percent possible or not?

Can the "microsoft-whidbey-compiler" optimize on 64-bit-systems with
"feedback-protocol", or is the "intel 8.1-compiler" better for bitboard-engines
?

What´s about the speed-increase of classic-32-bit engines (0x88 or similar
architectures) ?

I would be very happy, about a discussion :-))
