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?

No, it is many things, backwards compatibility being one of them.

The principal reason why x86 dominates in the middle and high performance spaces is that it simply has the best price/performance ration in that segment.

A POWER or SPARC processor may cost an order of magnitude more than the comparable x86 part. So unless the POWER or SPARC system brings a significant value added, most business tend to go for the cheaper price. Which is exactly what has happened.

A POWER or SPARC may cost more, but not the PowerPC, ARM, SuperH, or MIPS. All are either very competitive, or actually much less expensive. And that goes back to my point that if an x86 is NEEDED for some reason, like BC, it's not used; instead, the PowerPC, ARM, SuperH, or MIPS is used.

Which is why I said clearly that I was referring to the middle and high performance market segment.You know the one the article was referring to.

Can you find a SPARC or POWER processor with similar performance/price ratio as a modern x86_64 part?
