While we're on the history lesson here's some of the processors I pulled from my rigs over the years.

Bottom left the famous 80386 or "386 DX 16 MHz" above it the add-on 80387 Math Co-Processor. Above those two the equally famous 80486 Or "486 DX @ 33 MHz"
To its right the brain dead 486 SX 25 MHz no math co-proc). To its right it a very great gaming processor the PII @ 333 MHz Bottom right a P4 2.0 GHz, to its left a PIII @ 866MHz and a very capable Pentium PRO @ 200MHz which used RISC and whose L2 256KB cache operated at processor speed
That 486 is what powered my Duke Nukem gaming
