hey, I prefer building my own machines too, but there are rational
reasons that people pay the premium, for brand name boxes.
for instance, for grant-related reasons, my desktop is a Compaq
P4/1.7G. while I was pissed that someone choose this for me without
asking, it is a very nice machine, which would not be doable as a
whitebox PC. not exactly. for instance, it's quiet, and contains
some interesting airflow engineering. the board is mundane, as are
all the components. but I expect the PS and CPU fan will also last longer
than a noname part from the corner computer store. and it comes with
a three-year warranty, which some people consider to be critical.

and a PE 2600 with 2x2.4/1G/18G would be $4k. people often don't realize
how amazingly expensive chassis are. for a cluster I just ordered,
we're paying something like 30% of the per-node price for the chassis!
using rock-solid white-box parts, the aforementioned cluster will have
2x2.4G xeon nodes for about $1800 apiece.

I don't think so. Dell's pricing structure is more up-front than
the traditional vendors like HP/Sun/IBM. if you wave a Dell quote
at your HP rep, he'll probably come close to matching the price.

I don't believe Itanium is close to an appropriate price-performance point
for anything except very unusual applications. current IT2 machines are
not terribly impressive CPU-wise, but definitely deliver a lot of bandwidth
(6.4 GB/s dram bandwdith as I recall, with extremely wide onchip buses.)
if that floats your boat, great. they're too hot and expensive for me,
and I fully expect Opteron systems (with 6.4 GB/s dram *PER*PROCESSOR*)
to be a LOT cheaper. if I can get a dual-xeon e7500 board for <$400 today,
I expect a much nicer dual-Opteron board to be <$800 in 6 months.
I think everyone is still guessing about prices for Opteron chips themselves;
the core is supposed to be approximately a thoroughbred, and the HT and dram
interfaces are not terribly complex. if they ship with 1M cache, that'll
definitely drive up the price, though not all that much. I guess Opteron
will cost $600 or so shortly after intro, which isn't bad.

they can't afford to, IMO. AMD needs to quickly start shipping lots of K8's.
yes, they also need a higher ASP than current K7's, but that's a given,
and not that hard.
AMD has had a whole year to ramp up K8 production; if they don't ship,
say, 4M K8's in 1h2003, the company is gone.

afaikt, IT2 is big and hot and expensive to produce. that drastically
limits both its appeal in the market, and its appeal to Intel as a way
to use fab capacity. suppose (WAG) that Intel can churn out 4x as many
P4/2.6's as they can It2's on the same wafer/fab/linewidth. do they
have excess capacity to dedicate to It2's? are they worried about AMD
once again taking market share in the bread-and-butter desktop market?
I think of the It2 as a placeholder - not especially attractive to buy,
not wonderful to produce, but since it does well on spec, it's useful
for Intel marketing. the fact that hardly anyone buys them hasn't
hurt Ferrari, has it?

that's a VERY nice understatement. IMO, AMD has completely botched
their job of evangelizing Hammer. Intel, at least, has managed to
not completely lose ia64 credibility, in spite of being many years late.

AMD seems to confuse teasing with marketing. afaik, there are no useful
non-NDA facts available. AMD's official statements are not trustworthy,
since they so blithely stretch their roadmap.
