- Hello Everyone,
-
- Could someone please explain to me in clear, plain English the
- differences between architecture of different 80X86 chips ? I have a bet
- with a friend of mine who says that in the 80486 the math coprocessor
- is built in ONLY in the chips with clock speeds of 33 MHz and above. This
- seems odd to me as then what would be the difference between a 25 MHz
- 80386 (not SX) and 80486 ? I would very much appreciate it if the
- explanation would also include few words on the SX, DX, etc variants.
- Thank you.
