Intel With the Xeon 7600 line, Intel is finally using the 'R' word: RISC. It's targeting the mission-critical market dominated by Sun SPARC and IBM Power with the new chips, a first. Can the Xeon E7 processor deliver Intel's final blow to the RISC market, which includes its own Itanium?

Not the high-end, but the middle could have been dominated by PowerPC except for BC issues.

And before that MIPS could have dominated, and before that SPARC, and before that 68k, and...

They coulda, shoulda, woulda, but they didn't.


X86 has always had the advantage that it has rode both curves: process and microarchitecture. While most of its competitors were riding only one. PowerPC may have had an initial microarchitectural edge, but it was on a stagnant process.

Because businesses demanded BC. If IBM had picked anything other than the 8086/8088 for their first PCs, that would have been the main CPU today.

Not even always both, there were some not very impressive stretches. But it had enough.
