Re: Good CPU benchmark program?

Hi David,

In saying "Overdrive", you are referring to a program on the 486
upgrade diskette? Since I received some of those NIB I should have the
diskette somewhere. As long as it runs on a 286-10 system.

Exactly, though I never tried it on a 286 system. It did work with the BL-66
and a separate 387-class FPU, 20 Mhz Cyrix, I think. I still have one 486
DX2-66 NIB.

FPU performance isn't real critical right now, but the IBM SLC CPUs
are
supposed to be optimized for the Cyrix 387SX/SL version. If there is
another
utility I can check the 287-10, 387SX-25, & a 387SL (multi-speed, so the
later 387 core) against each other. I might even have a 287XL (also with a
387 core) around too.

The 486 overdrive diags perform a series of FPU/CPU instruction tests
without benchmarking them (the speed test is a separate menu option). IIRC,
the 387 Cyrix mentoned above failed to conform with the sine or cosine
functions.
