Re: [9fans] AMD Sempron

yes. you can fuss over the micromanagement that
ekes out every fractional % of performance but unless
you are in a very specialised environment that's
just obsession. the chips either implement the
instruction set and architectural features you expect
or they don't. plan9 expects little from the cpu.

as usual, what's round about the cpu is the problem,
graphics, network, and now to some extent usb (and
sata?) being the primary concerns for support. but,
of course, device drivers aren't hard (are they? if
they were why do other operating systems have so many,
coded by such obviously mediocre programmers?), so a
little elbow grease should fix that.

case.

it's interesting with all the marketing going on right now you need to be
quite savvy to figure out what you're really getting. a bit like the days of
hand-built computers.

the D0 is the same but might (!) not support 64bit and the cache
sizes are half as bug.
(64/128 vs. 128/256).

Bloody hell. Let's just simplify the whole mess and give them all a
brand name of CPU™.

I've have a new plan: I'll buy the Sempr0n box to use as a
replacement for my BSD server, and run Plan 9 on the old box (a Via
C3 Nehemiah). This works better anyway, as the Via "server" will
actually fit on the boat ;-)
