They screwed up the TSCP benchmark:

Yes the Anand test is real evil and childish

a) they just test tiny programs
b) for example the prime bench the author says on the homepage:
"primegen is a small, fast library to generate prime numbers in order. It generates the 50847534 primes up to 1000000000 in just 8 seconds on a Pentium II-350; it prints them in decimal in just 35 seconds. "

c) I tried to reproduce something and couldn't. Note that TSCP has *no* makefile for linux at all. One of them didn't compile at all under linux as it is microsoft only. They say they tested under linux but they only test 32 bits intel c++ executables, why?

They get with tscp 155k nps.

While someone else is gaming at the dual opteron, i take part of 1 cpu and get :
311k nps

Here is my output i get with tscp and that's without PGO even:

diep@data tscp181 $ gcc -O3 -mcpu=k8 -o tscp board.c book.c data.c eval.c main.c search.c
diep@data tscp181 $ ls -l tscp
