I remember the exchanges very well, and I remember what the local AMD
chorus was saying. AMD took a gamble on very long odds, IMHO. The
fact that they were going to 64-bits didn't shorten those odds. They
had to change the instructions set, move the controller onto the die,
develop a new memory interface, and go to a new process. Not exactly
a conservative move.
GMAFB, they did *not* change the instructions set. It is still x86, and
*backwards* compatable, which is the key. They did move the controller
on-die (an obvious move, IMO), but certainly did *not* develope a new
memory interface (what *are* you smoking?). They also dod not go with a
new process. The started in 130nm which was fairly well known. I don't
see any huge "risks" here at all. The only risk I saw was that INtel
would pull the rug out with their own x86-64 architecture. But no, Intel
had no such intentions since that woul suck the life our of Itanic.
Instead they let AMD do the job.
The AMD chorus here wanted: AMD win, x86 win, 64-bits. That, not any
realistic assessment of AMD actually succeeding, was what everybody was
betting on. Well done for AMD and IBM that they could make it happen,
but far from a safe bet.
Nonsense. I was betting on the outcome, and unlike you, with real
greenies. ...and don't blame IBM for pulling it off. It was all AMD.
IBM is in business of making money, nothing more.
I don't think Intel's plans for Itanium had much of an effect on the
success or failure of the x86 offerings of AMD and Intel.
Bullshit! Intel wanted Itanic to be the end-all, and to let x86 starve to
death. AMD had other plans and anyone who had any clue of the history of
the business *should* have known that AMD would win. They won because
their customers won. Intel will make loads of money off AMD64, but they
don't like it.
As Felger pointed out, the money went into Prescott.
Felger and I have been knwon to disagree. Because he agrees with you this
time, he's now the authority? I see.
You're both wrong. The money went into Itanic! Then an ice-berg
happened. Prescott was what was left of the life-rafts. ...not pretty.
For the return Intel got on
that investment, Intel might almost as well have put that money into a
big pile and burned it (yes, that's an overstatement). The advice that
Intel _should_ have followed would have been to have canned NetBurst
long before they did. Netburst, not Itanium, is the marketing strategy
that gave AMD the opening.
Wrong, wrong, wrong! You and Intel have the same dark glasses on. Itanic
was the failure. "Netburst" was the lifeboat with the empty water
containers. It was too little and *way* too late.
You can repeat yourself into next week, but you're still wrong.
Go just as fast as you can without wasting cycles, but no faster.
Netburst broke that rule. It was painful the instant the P4 came out,
it got more painful as the scale shrank, and finally it became
unacceptable.
You really should study microarchitecture some more. What broke the P4
was sill marketeering. It was too big to fit the die given (by marketing)
so they tossed overboard some rather important widgets. The fact that
caused them to have to bring the silly crap to the market was the
failure of Itanic caused by, TA-DA, AMD64. P4 would never have seen the
light if Itanic didn't take a few well-placed (and self-inflicted)
icebergs.
We'll just have to disagree about this.
You can disagree all you want. It's in the history books now. Physics
had *nothing* to do with this battle (AMD and Intel both are constrained
by the same physics, BTW). It was all marketeering arrogance. INtel
simply won the arrogance battle, and lost the architecture war.
I think it's safe to say that Intel didn't plan on spending all that
money for a redesign with such a marginal improvement in performance.
Somebody scoped out performance targets that couldn't be hit. Maybe
they hired a program manager from the DoD.
Intel is a marketing driven company. They are responsible for this mess.
It had *NOTHING* to do with circuits (yeesh). I'm quite sure (without
first-hand evidence) Intel's curcuits are still superrior to AMD's.
Intel's helm _was_ "frozen" though.
Intel certainly wanted to contain x86.
"Contain" it in a casket, perhaps. Intel had no interest in having x86
survive. All the patents were either expired or were cross-licensed into
oblivion. Why do you think Intel and HP formed a seperate company as a
holder of Itanic IP?
That's something we can agree
on. Intel's major vendor, Dell, would have done just fine hustling ia32
server hardware if the performance had been there. The performance just
wasn't there.
Dell is simply Intel's box marketing arm. No invention there. Who cares?
