- Lots of 'good' CPUs have given up the speed race for a variety of
- reasons - Motorola's own 88K failed to gain enough popularity because
- of it's late entry, Intergraph just gave up developing the Clipper and
- switched to Intel CPUs 'cause it was cheaper and their strength was in
- software anyway, Intel ignored the workstation potential of its own
- i960 RISC CPU, and Motorola's 68K line has moved to the embedded
- market where speed is not the most important factor (the latest
- related version, the ColdFire, is actually slower than the '060, but
- smaller, cheaper, and uses a fraction of the power - which is why it
- drives the newest HP Laserjet 5 printers).
- It was more a political decision to de-emphacize 68K development
- in favour of PowerPC - RISC is simply easier to speed up than CISC
- designs, and it's hard to compete with Intel's CISC resources.
- Technically, the 68060 is roughly equivalent to a P6/Pentium Pro,
- except for clock speed, and I can't see any reason P6 technology
- couldn't make a 68060 as fast or faster.
- But who'd pay for it? Workstation makers had gone off on their own,
- non-Intel PC makers were no longer commercially competitive except for
- Apple, and embedded customers didn't need fast CPUs when DSPs or
- custom ASICs were cheaper for the same performance result.
- Maybe Apple's support could have paid for it, but they simply
- couldn't wait. The 68060 architecture is similar to the Pentium Pro,
- not the Pentium, and so it took longer to develop than the Pentium, so
- for a while, Motorola had nothing that could be competitive. Apple
- couldn't afford to wait that long, so went for the PowerPC.
