This article mentions 4Mnps: http://news.bbc.co.uk/2/hi/europe/1466810.stm That Pentium III 1GHz number seems to be inflated since Pentium 4 and 2GHz shows...

Which CPUs was used against Kramnik in 2002 ?

Is there any official information about that on the Internet ? I found " Fritz ran on four Intel Pentium 4 Xeon CPUs at 2.8 GHz. " from https://en.wikipedia.org/wiki/X3D_Fritz and " 8 processors at 2.4 Ghz + 256 GB memory " in French https://fr.wikipedia.org/wiki/Fritz_(programme_d%27%C3%A9checs) Wh...
