Yeah... I figured that you had to have a pretty advanced design (with an
accompaning fab, although I don't really know about this stuff, it seemed
like 1 micron was the magic number for on chip caches). I've always liked
large caches on everything: 512K on a hard drive, a meg on a motherboard,
64K on chip (Sure, doesn't seem like much to today's memory-eating
programs, but I look at it this way: It's as much RAM as my Apple II had.
But the II could do a LOT more with it's 64K than mine can...) BTW, does
the PII actually count as a microprocessor? Sure, you've got the
processor, then you've got the cache (IIRC) on a seperate chip mounted on
what's more like a daughterboard than a processor. So if you say that for
a PII to be a PII you need 512K cache, is it a microprocessor?
