As for 486 vs 68k performance, I have an A1200 with a 68030 accelerator (CSA 1250 12-Gauge) clocked at 50 Mhz and ran benchmarks against a 486DX 33. Performance is about equal even with the huge difference in clock speed. So paolone's remarks are spot-on in spite of all the irrational remarks that will be made about the 68k family and how it's "superior". It certainly is NOT superior.
It's fair compare an 386 against 486? because 030 was made to compete with 386.and you are comparing with an 486. 040 is the competitor of the 486, and i suspect that if the 030 is almost in par with the 486 then 040 is faster than 486 at the same clock speed.The 060 was made to compete with pentium when the fastest pentium was 100 mhz.I do not have benchmarks but i think that 060 50-66 mhz is as fast as pentium 100 or more in some operations.Of course we are talking abot raw CPU power because overall speed of the system the Amiga sweeps common PC of the era.What made me decide definitely for an Amiga was look a 486 in action, it was in ridiculous compared to the unexpanded Amiga 500 so i definitely bought an Amiga 1200
