Even besides new instructions the 486 and then Pentium ran existing x86 code faster than the 386 clock for clock. Various new instructions did add capability but just running existing code faster was a huge win on subsequent chips.
- TacticalCoder 3y agoYeah. Not many new instructions but many instructions required less cycles per instruction and the 486 also got way bigger caches. And the integrated FPU (IIRC the FPU was an add-on for the 386). Switching from a 386 to a 486 was bringing a huge speedup back then.
