Hey you two fighting cocks ... :-)

Let me quote from Hsu's IEEE Micro article again (page 72).

"The chess chips provided enormous computational power.
 On a general-purpose computer, the computation done by
 the chess chip for a single chess position requires
 *** up to 40,000 general-purpose instructions ***. At
 2 to 2.5 million chess positions/s, one chess chip
 operates at the equivalent of a 100-billion
 instruction/s supercomputer."

Clear enough now? Hsu's estimate obviously reads:

1 chess chip ~= 40,000 general-purpose CPU instructions
                       per node
