Not really.. It's just that I see lots of posts of "MY COMPUTAR IS TOTALLY
STABLE UNLESS I RUN A PROGRAM ON IT!", just wanting to make sure you weren't
one of them.

Compare max power (which intel don't publish) to max power for the same level
of performance (which puts a 1.4Ghz Tbird around a 1.9Ghz Willamette 'ish) and
you'll find they are actually fairly close.

Also, Athlon's tend to run hotter even though the actually heat energy is the
same, because the die is smaller (hence it's more difficult to dissipate the
heat)

The new 0.13 Thoroughbred cores are ~40% smaller than Palominos, with ~15%
less voltage. so the watts/cm^2 has actually gone up.

The southbridge in a 'classical' chipset (AMD 761/VIA KT133/Intel 440BX etc)
is just a PCI device, unlike the current trend of having a dedicated high
bandwidth bus between the north/south bridges (Hypertransport, V-Link or
otherwise) or having them on the same silicon like SiS have been doing.

IOW, they weren't designed "to work with that chip" they were (VIA aside :p)
designed to work as standard PCI devices.

Took them ***y long enough tho' :/

Oh yea? Maybe I'll get me one of them Cyrix processors then. :-)

And the KT266 is not _that_ much faster than the SIS 735 to begin with.

clock for clock heat comparisons need to be balanced out against the relative
clock for clock performance however :)

...And consider the CMOS process technology used to produce the chips as
well. The 2.53GHz P4 uses a smaller process than the above mentioned AMD
chips, which gives it an advantage.

Btw, is that the typical or maximum power draw for the P4? Intel usually
only lists typical while AMD lists max. Max for a P4 is often 10W or more
higher.

Yes and I think you will find that a P4 2.53 is faster than a 2200+ Athlon.

Tbreds & P4 Northwoods both run on a .13 micron process

I dont have figures for .18 Willamettes but I have no reason to believe that
Intel's .18 process is any worse than AMD's in fact I'd bet that it's
better, AMD chips are notorious for running hot if Intels were as hot  then
AMD wouldnt have this notoriety.

These are typical ratings for both sets of chips, you can add another 7 or
so watts to AMD numbers as well, for instance a 2200+XP has a typical rating
of 61.5 watts and a maximum of 67.9 watts.

2200+ Athlon's are around $225.  P4 2.53's are around $650.

Not much of a bargain for about 1 point on the richter scale.

Yeah, right. I read tbird and not tbred. Heh.

Why would you bet that?

Yes they would. People are more likely to suspect and ascribe bad properties
to AMD than Intel, for what reasons I'm sure you understand yourself.

Anyway, they really ARE about equal when comparing max draw, at least for
.18u incarnations.

-Larry

Yeah, this is true.. (unless it's floating point heavy code, in which case the
Athlon will rip it a new one)

what's the _peak_ heat output from a 2.2Ghz Northwood?
