This is a big difference; the MMX-using engine seems to be a (nearly) complete
different program. It was reported here, that Frans Morsch had said he uses MMX
registers for 64 bit bitboard operations (at least that's how I remember it).
AFAIK that would mean that large parts of the program are very differently
designed.

People have noticed the behaviour (also in test positions) of the Fritz 7 (No
MMX) engine is similar to the latest Fritz 6 (single CPU) engine.

I've heard Deep Fritz was MMX only already.
