Not ones that I noticed running computational chemistry jobs on it under
Linux. If Intel wasn't firesaling 80521/150s (at about 55% of the
price of a K6/166 these days) I'd be stocking up on them and retiring
a lot of my K5 processors.

It's within 5% of the speed of a similarly clocked 80521 -- the only
place where it does not perform nearly as well is the floating point,
which is a place where AMD and Cyrix have (rightly) decided that it's
not worth the trouble to tune, because almost nobody uses floating

david parsons \bi/ The K6 works fine, if you're not doing computational
\/ chemistry.
