The main reasons for the 75 mhz version were to make Pentium work on cheaper motherboards (50 mhz bus speed instead of 66), and because of pricing pressure coming on from AMD's 5x86-120/133 chips released in 1995. I bet the Pentium 100 launched cheaper than the 68060 50, 66, or 75 mhz..
I was comparing the CPU designs and the only way to do that was to choose as similar of products as possible.

At the time, power consumption was not as important for "desktop" gamers as I noted (it is much more important today). I believe the 68060 and Pentium were close in their initial target as the next generation of a CPU which could be used as the basis for further enhancements. IMO, both teams were successful in this but then the 68060 was abandoned for the PPC. The 68060 was a great CPU for embedded and mid-range desktop use where resources were limited but ignorant suits up top dropped the axe on it after the AIM agreement.

(An A500+/A600 with a 68020@ 25 mhz, and an A1200 with a 68030 @ 32mhz certainly wouldn't have hurt market share). The 68000 was already 6 years old by the time the A1000 launched...
Absolutely. Motorola had management and marketing hindrances.

I agree. The biggest factor was the economies of scale from the PC boom and then 3D gaming boom putting huge cash flows in the Intel sales and wiping out their past mistakes. The RISC hype was at full steam which sold CPUs for high end computers while the 68060 did not get much attention. The 68060 was an excellent design and better suited for embedded, laptop and mid-range desktop use than either the Pentium or RISC. Sadly, the 68060 was a successful design which was mis-managed (ironically by Motorola which lived on embedded sales) and mis-marketed (practically anti-marketed by Motorola).
