Intel reveals details of new CPU design

At 14 stages, the main pipeline will be a little bit longer than current Pentium M processors. The cores will be a wider, more parallel design capable of issuing, executing, and retiring four instructions at once. (Current x86 processors are generally three-issue.) The CPU will, of course, feature out-of-order instruction execution and will also have deeper buffers than current Intel processors. These design changes should give the new architecture significantly more performance per clock, and somewhat consequently, higher performance per watt.
