I’m still convinced whoever was in charge of naming the 386 and 486 processors suffered from some kind of multiple personality disorder.
Sounds like a Marketing Guru....
I was on the Intel validation team when many of the 486 processors came out.
At one time we had 50 separate versions all based on the same die.
For instance, the difference between the DX and DX2 was a wire bond option which made the core run at 2x speed.
Naming all the parts was much easier than validating all the possible permutations.
