I'm pretty sure that there are only 4 instruction set revs
through the R12000.  MIPS-1 was the instruction set provided
on all the MIPS chips up through the R3000; the R4000 series
added the MIPS-2 and MIPS-3 instruction sets (MIPS-2 adds
some new 32-bit instructions, MIPS-3 is the 64-bit version);
the R5000 and newer add the MIPS-4 instruction set (new
multiple-add instruction, plus other junk...)

Right.

It could be something as simple as the manufacturer's chip
number (e.g. MC68000 for a Motorola 68000 CPU); there is some
use in grouping some processors, but I agree that the current
keywords don't cover things right.

Using the naming in the spec, it would probably be "x86-64", but
that ignores differences between processors, e.g. MMX vs. non-MMX,
instruction sets, etc.

As I recall, McKinley will have some new instructions, even though
it too will be 64-bit...
