Hi Vincent,

> divide by 1.7 for chessprograms to have the real speed of it in AMD K7 Mhz.

You know that this depends on the engine... As much as I know about Diep (And I
do not know much... :) your 1.7 could be quite possible... I have tested here
with a PIV-1600 (SDRAM) -> and for Quark the factor was 1.53, so a PIV 2400
would be around the same speed then my current Athlon XP 1800+ (1566 MHz.) It is
possible that the PIV 2400 with RAMBUS could outperform my Athlon, but I doubt
that due to the structure of RAMBUS which is not so perfect for chess... When
discussion comes to speed / price Athlon is still the best choice...

Greets, Thomas

P.S.: Besides, I have also tested on an PIII-1266 here - it was just 1.13 slower
then my Athlon, so in speed per clock it is a real monster... to bad that intel
has given up the PIII-structure... But for other engines this might differ
also... a possible reason that this PIII-1266 performs so well might be, that it
has the big on die cache with 512 KB...
