Is there certain processor that has been particularly capable in chess
- for instance,
Pentium M, Athlons, P4's, dual cores ? Is this also engine dependent?
Do dual
core systems benefit from other core in some engines ?
How about cpu usage, it seems that p4 531 is giving only 50 % of cpu
for an thread
of Fritz or Rybka engine while playing with it in chessbase server ? Is
there way to
give more cpu power for it - setting higher priority in task manager
doesn't change the
number?

My new Mac with an Intel dual core processor runs Fritz9 analysis twice as
fast as my P4 PC (over 1000kb/sec vs abut 500 for the PC). However since I
haven't reinstalled Windows on the PC for over 3 years, it may have junk
running in the background slowing it down. If not, then the dual core
processor gives a huge increase in speed with Fritz9.

Fritz 9 itself can't use the dual cores. The speed increase you are
seeing is solely caused by the fact that almost any processor is more
efficient for chessprograms than a P4.
