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.
