- I can't say that I have any first hand experience with the Cyrix/TI
- chips, but my guess is that if there were _any_ major problems with
- them, Intel would have made the world _very_ aware of them. (And we
- would have seen complaints on the net...)
-
-
- The scoop seems to be that the Cyrix chips and the TI chips (which are
- really Cyrix designs), implement the full 486 architecture with _very_
- few exceptions. The differences between the Cyrix chips and Intels
- are less significant that some of the differences between various mask
- revisions of some of the Intel chips. (i.e., the 32-bit multiply
- problem with the 386, the tan problem with the 486, the over heating
- problem with the 486-50, etc...)
-
-
- The Cyrix chips do run slower than the "equivalent" Intel chips due
- too their smaller cache, having to have an off chip floating point
- processor and because they run with a 386 type memory bus. This _may_
- be significant for your application, on the other hand, it may not.
- Try to get BAPco SYSmark or SPECmark numbers of the machines in
- question if you can. (but you probably can't. *sigh*)

- $200 is a fair amount of money, and I might be tempted to use that
- $200 to by more memory, or a larger hard disk even if it ment having a
- slower CPU...
