- My understanding is that the performance gain from the Cyrix
- chip is due largely from the cache. Most i386 motherboard
- have an external cache. I think you would have cache coherency
- problems between the internal cache and external cache, because
- the cache controller on the i386 motherboard wouldn't be aware
- of the internal cache.
-
- Cyrix performance claims are generally based on modified i386 processor
- motherboard. So without enabling the cache I doubt you'd see a big
- performance boost.
