My recollection (starting with the K6-3+ and then going to the K6-2+ - if
there are any errors, please correct me):

The K6-3+ is a K6-3 produced on a smaller process (180nm, as opposed to
the K6-3's 250nm (I think it was 250, anyway)). Some of these also have
PowerNow(tm), which is like Intel's SpeedStep(tm) but with a wider range of

The K6-2+ is a K6-3+ with half of the on-chip L2 cache disabled.

Anyway, my previous email was describing the rationale that AMD used to
arrive at the K6-2+ name.
