- Comparing 486SX performance to 486SLC performance is an apple-vs-orange
- comparison - the 486SX has a 32 bit bus, and the 486SLC has a 16 bit bus.
-
- A more balanced comparison would be between a 486SX and a 486DLC at the
- same clock speed - and I would expect the 486SX to win by about 10% at
- the same clock speed.
-
- I am surprised Rod Skinner did not notice the discrepancy.
