To make it clear, the chip itself must be optimized to take advantage of a 32 bit program. The pentium, pentiumMMX, Cyrix 686, K5 AMD, and 486, are not optimized to run 32 bit programs. They will run them but not any faster then 16 bit programs. The pentium pro, Pentium two, K6, are optimized for 32 bit programs and you should see a nice performence gain if you go from a 16 bit version of a program to a 32 bit version of that program. If you don't have an optimized chip you will see little or no gain. This can be tested out with Fritz 5.32 If anyone has it running on a P200-233MMx chip and they also have Fritz 5.16. See if Fritz 5.32 is running faster by testing some positions with it. I bet you will see little speed difference in the two versions. On a P II you will see a big difference.
