For some reason, your Axon Benchmark only gives a 10-12% advantage to Athlon 64 compared to Athlon XP (given the same frequency). From the tests I have seen in the CCC Forum, with different chess programs, the advantage is more like 20% (see also the FritzMark, in kNodes/sec). Perhaps your Axon v1.0 chess engine is not representative of today's main chess programs... On October 27, 2005 at 06:04:29, vladan wrote: > >Dear mr.
