Ah, another myth to bust. Intel did not come up with

AHH! Thanks for the correction. I should've known not to believe
their marketroids.
It attempts to take advantage of thread-level
parallelism, as
instruction-level parallelism (leveraged by superscalar
architectures) still leaves a fair amount of 'dawdle time' for the
chip's functional units. Modern multilevel memory architectures
are pretty good at keeping processors fed -- Ian
Yes.
