Yes.

If you look at my TSCP benchmark page, you can see that a 200MHz Pentium runs
TSCP just as fast as a 200MHz Pentium MMX.

The Pentium MMX has more L1 cache than the regular Pentium, so that means TSCP
will run (almost) entirely out of 16k of cache.

So the fast L2 cache of the K6-3 should not make a difference for TSCP. It will
make a difference for some other programs, though. (Rebel is evidently one of
them.)
