RE: Overheating CPUs...

["Don McAllister" <donmc@xxxxxxx>]

This is all a bit worrying when leaving machines on 24x7 from a safety
aspect ie likelyhood of fire if a fan falls off a processor. I have several
machines left on 24x7 in my office at home and now feel slightly nervous.

Thats really a rather narrow view Mark, and reflects AMD as a company
before
a lot of the movements in the Semi industry. When IBM stopped fabbing x86
procesor cores, a lot of their guys moved to AMD for instance, and I
understand a couple of teams shifted from Nat Semi to AMD also..

In particular, AMD's Dresden fab (the one that makes the AXIA-Y series
Athlon procs) is considered the leading facility in the world, and produces
yields in the high 80% range, as opposed to Intel's Irish fab, which I
understand was managing somewhere around 50%-60%

There was extensive coverage of the fact that Intel had to abandon their
policy of underrating CPUs, simply because they were unable to produce the
higher rated ( >1GHz ) procs at an economic yield level.

Whether you want to just run win2K as a desktop, or play games (the
ultimate
system load) Thunderbird Athlon procs can the absolute pants off of Pentium
III or 4 dies at the same clock.

As for reliability in normal use? (ie, not a failure condition) I have
noticed no difference....

Not to mention that if it fails, a top line 1.4GH Athlon T-Bird is selling
now for £75 rather than £399 for the 2.0 Ghz P4 (with equivelant
performance
in 3D Mark 2001)
