After delays and much waiting Intel's first 90nm processor is here. The biggest news, though, is the new processor core, code-named Prescott. Prescott isn't just a die shrink, though it is that. Prescott is also a major reworking of the Pentium 4's microarchitecture--major enough that I'm surprised Intel didn't opt to call this processor the Pentium 5.
