- In a previous article, Matt_Kievit@abcd.Houghton.MI.US (Matt Kievit) says:
-
- >> The differences between the 486SX and the 486SLC/DLC are:

-
- But it doesn't have a floating point unit like the 486 dx ....
-
- Anyway, here is the matter as I understand it:
-
- IBM 386slc - 16k cache, 486 instruction set, 16 bit external data path
- IBM called it a 386 to be polite, but once cyrix broke the taboo we got
- IBM 486slc - 16k cache, 486 instruction set, 16 bit external data path,
- clock doubleing
- Cyrix 486slc - 1k cache, 486 instruction set, 16 bit external data path
- Cyric 486dlc - 1k cache, 486 instruction set, 32 bit external data path
-
- None of these processors have a built in floating point unit.
-
- Infoworld is going to be having a special section next week (Jan. 18th)
- comparing these chips and their performance relative to intel's products.
