- The 386 and 486 instruction sets are different. The 486 added extra instructions
- for cache control, ...
-
- To most people, the instruction set determines the processor. Clock speed, bus
- size are independent attributes that are often denoted by suffixes. E.g., a
- 386SX @ 10 MHZ is no less a 386 than a 386DX @ 40 MHz. If Intel (or AMD) were
- to introduce a 386SXX 5 MHz that has an 8 bit datapath, would you call that an
- 8088 instead? Do you class the 386SX as a 286 because of the 16 bit path?
