SMT is of little or no consequence to chess programs. It might even slow it down. You don't think it automatically doubles the amount of functional units on a given CPU, do you? And a 1.6GHz P4 is really slow for integer computations. A dual 2100+ XP system will compare pretty favourably to a four way system of those 1.6GHz P4 Xeons. So you would need an 8-way system to get ahead. And the Intel cache coherency protocol might bog down the memory sub-system. The 8-way P4 Xeon system might be the fastest x86 system. But it might not be more than a binary order of magnitude so. It would be possible to write a program especially tailored to it, though. MvH Dan Andersson
