Wrong! A medium sized and priced fpga should allow an enhanced 68k processor to achieve around 150MHz.
Wow, a whole 150Mhz?
I know MIPS aren't everything, but it's one indicator with numbers that were readily available on Wikipedia.
Assuming 060 performance, not 020/030 as most fpgas currently are:
68060@66 MHz = 88 MIPS
68060@75 MHz = 110 MIPS
68060@110 would be roughly 220 MIPS
Intel Pentium III @ 500 Mhz = 1,354 MIPS
ARM Cortex A8 @ 1.0 GHz = 2,000 MIPS
PS3 Cell BE @3.2 Ghz = 10,240 MIPS
XBox Xenon PPC @3.2 GHz = 19,200 MIPS
Intel Core 2 QX6700 @ 2.66 GHz = 49,161 MIPS
Intel Core i7 i980EE @ 3.2 GHz = 147,600 MIPS
x86 is clearly fastest per dollar now and will be for the foreseeable future.
Even the cheap embedded x86 chips are faster than the PIII 500MHz.
You can buy an off the shelf x86 that is
1677 TIMES FASTER than the fastest 060 available (66Mhz) for less than the cost of the 060 card.
I'm not sure why anyone would want to hobble Amiga with slow CPUs, they used the 68000 because it was the fastest for the money at the time.
Before Amiga went under they were already looking for alternative CPUs, so I'm not sure why there is such a strong attachment to a basic component that was near end of life already.
