- From my understanding of the 486SX, I thought it was a worthless
- scam to sell more chips. But they seem to be so popular (relative
- to what I would expect) that I'm wondering if I'm missing something.
-
- I am under the impression that the 486SX is really a 486DX with
- the FPU disabled. And the 487SX is really a full 486DX, and when
- it is installed into a 486SX system it bypasses or disables the
- 486SX chip. The combination of 486SX + 487SX is more expensive
- than a 486DX. This seems like a very inefficient design to me. :-)
-
- Obviously one wouldn't buy a 486SX + 487SX right off the bat, when
- one could buy a 486DX for less money and the same functionality.
- Or would one? Has anyone? Why?
-
- Does the 486SX chip somehow consume less power than a 486DX? (like
- a 486SL does?) Is it a newer rev of the 486 design? What is it
- about 486SX hardware that is selling?
