Right, but intel makes quite a few announcements, and the 2600+ announcement
came BEFORE the p4-2.8 announcement and WELL after the p4-2.53 announcement.
So actually intel announced right on the heels of the AMD (today for intel
vs last friday for amd).

Well the hardware reviewers are a dime a dozen, I've yet to see error
bars, or any other indication I should look at 1 maybe 2 significant
digits of their results.

I read a couple.

Hrm, okay how about:
http://www.amdzone.com/articleview.cfm?articleid=1198&page=2
Typical Thermal Power: 62.0 W

I couldn't find the table I was viewing, but found the Thermal design
power for the p4-2.53 is 59.3 watts, as close to a comparable number
as I could find.  IMO in the noise compared to fan rpm, heat sink
differences, heat sink compound, application pressure, case ambient temp,
case airflow etc.

As far as I'm concerned it's in the noise, even things like the angle
of an ide cable can affect airflow across a head sinke

I'm asserting that a XP2600 ~= p4-2.6.  For example:

http://www.amdmb.com/article-display.php?ArticleID=202&PageID=9

The Athlon XP 2600+ processor is the fastest processor on the market
without a doubt; even overtaking the Intel Pentium 4 2.53 GHz setup that
we have here.



http://www.tomshardware.com/cpu/02q3/020826/p4_2800-16.html#conclusion_change_in_power

Conclusion p4-2.8 is faster (no surprise), my claim is xp2600 != p4-2.53:
As always, price-conscious buyers who are interested in getting the best
price/ performance ratio are a bit better off with an AMD Athlon XP than
with a P4..


http://www.tech-report.com/reviews/2002q3/athlonxp-2600/index.x?pg=10

Heck, Intel has a fight on its hands right now. The Athlon XP 2600+ isn't
the outright fastest x86 processor in every way, and it didn't even win
on a majority of our tests. Still, the 2600+ took top honors in Business
Winstone, flouted its FPU in Serious Sam, burned through our test render
in POV-Ray, and absolutely laid down the smack in ScienceMark.

Results vary, the athlon xp 2600 is much faster then a poor p4-2.53
(i.e. ddr), but somewhat slower on some benchmarks when compared to
a dual rambus channel system.

Even if I made $80k a year, I'd probably still buy the best
price/perf system as long as it was 80-90% as fast.  I'd rather
save the $500 (1 GB ddr is a fair amount cheaper then rambus, 
athlons/266 boards are much cheaper then the dual rambus boards,
the cpu's are a fair amount cheaper as well) and apply towards
upgrading the system 6-12 months sooner, or *gasp* spend it on
something else fun.

Thus I wouldn't buy a radeon 9700 today for $400, I'd spend $140 on
a gf4-ti-4200 then wait 6-12 months and get something much faster
or at least much cheaper then the radeon 9700, say a NV30, or maybe
a future radeon that has a dramatically better price/perf ratio.

In the last years 3d cards have been increasing in speed even faster
then the cpu's.  Alas this also means that power and heat budgets are
being increasingly taken up by the video cards.  I think the 9700
actually requires an additional power connector *gross*.

Well, I'd hold on unless your desperate.  Future upgrades to the
FSB are close, the nforce 2 is close, and even the hammer isn't to far
away.
