Whatever happened to x86-64?

Adorable little Ed Stroglio rant:

Hatching Eggs . . .
"Remember x86-64? The stick AMD was supposed to beat Intel to death
with?

Then Intel got themselves the same stick, and the would-be beaters
found something else to talk about. Yes, AMD is doing better now, but
not because of x86-64. Indeed, AMD's increased fortunes have come well
after Intel switched.

Microsoft came out with a Windows XP for x86-64, but the world hasn't
exactly stampeded to get it."

I always thought the reason nobody flocked to XP x64 was because
Microsoft delayed and delayed so much to let Intel catch up that people
lost interest in it? I mean you know Microsoft was delaying here, even
Solaris 10 came out for x64 before Windows did, despite starting work
on it 2 years later.

"How many of you bought CPUs back then at a premium primarily because of
x86-64?"?? I got my Athlon64 ~15months ago and I don't recall paying much
of a "premium" for it. Hmm, must have been a slow day chez Ed!

I'm still not 100% sure about that. Its also been suggested that M$ was
just somewhat less than competent. They also knew that AMD's supply was
not going to carry the market so apply a bit of Parkinson's Law as well and
a new-found(?) desire to provide "security" and that accounts for a fair
part of it. As Tony has remarked, it *did* take them a while to get WinXP
SP2 out the door.

I did. I bought my socket-940 Opterpon about 20months ago and paid a
rather large premium for it (including the registered memory). I decided
that I was ready for a new system and that since I was still using the
(then) four-year-old K6-III I was goign to skip the K7 generation entirely
and move on to AMD64. I'll quite likely have this system at least another
two years, perhaps far longer.

....a small part of the reason I moved onto Linux.

It's an ironic world we live in, when people find you more acceptable
because you're incompetant.

There were good reasons for it to delay introduction of SP2, as they
were trying to fix a leaky boat. At that time security on Windows seemed
like swiss cheese. However, they had x64 finished much earlier, even
though they kept releasing release candidates. They were hoping for
device drivers to be released, but nobody would release device drivers
until Microsoft released the OS. They could've released x64 and still
released SP2 for 32-bit.

Really the most telling sign that they were delaying was the fact that
Sun Microsystems started development work on their Solaris 10 x64 about
two years after Microsoft, and still released it six months before
Microsoft! One could say that Sun has years of experience with 64-bit
operating systems, and Microsoft doesn't. But Microsoft already had
64-bit source code for Windows in their Itanium port, and other than
low-level assembly language differences, most of it would be the same
between the two architectures, just a recompile away.

If Windows x64 had been released near to when AMD had released their
hardware, even if AMD didn't sell as many chips as Intel, the fact that
a released OS was sitting there it would've been gathering device driver
support ready for the time when Intel came on board. By the time Intel
was ready with 64-bit, you'd have a mature operating system already with
lots of device driver support. And people coming in with Intel would
have had much easier time. AMD users could've acted as the beta testers
for Intel users.

My Opteron system is close to 2 year old, and it never ran a single
line of 64 bit code. Back then when I built it, the reason behind it
was a dual processor system for just over a half of equal Xeon rig
price. Will it ever do 64? Only when there will be demand to do some
work that can't possibly be done under 32 bit OS. So far, never heard
of any requirement of 64 bit code in the section of software market in
which I make a living.

Sorta like the 386s? I consider the uptake of AMD64 to be
nothing short of phenomenal in comparison. In a far more
entrenched and less geeky market, we have day one OSes and a
remarkable amount of support. Even from the known laggard, MS.

IIRC the 386 had to wait 5 years for runnable OSes (IIRC, OS/2
v2 and non-beta Linux). Apps followed, and will this time too.

The case for 64bit over 32b is less compelling than 32 over 16.
So uptake will be somewhat slower in the middle part of the
life-cycle curve. But the start has been very quick.

There are still very few softw. that support 64, not to mention
_require_ it. I was surprized recently that Half Life II was released
in 64 bit version. However I am not going to run and by win xp-64 just
because of that.

Now if you need to address 8 GB of memory for some purposes (DB
server?), 64 bit is the only game in town.

Yup. I did some chip-level gatelevel simulations on an 98Mtransistor
chip, and just the SDF file with timing information is 8GB. In-memory
image size was ~4GB, so I had to go 64bit.

Starting the simulation up (annotating timing to all nodes etc) took
around 5 minutes on our Sun v20z dual-opty - I gave up trying after I
had waited 1 hour on our old SunBlade 1000.

I might've lost track of releases, but IIRC Server'03 has not been
released for AMD64 yet (I mean production, not betas and previews).
SQL Server 2000 (the current corporate work horse) will never go 64
bit. SQL Server 2005, while released, is still exotic. Besides,
lacking Windows Server to run on, the 64 bit version may run only as
developer edition on WinXP64, and in this environment you hardly ever
need more than 4 GB - I've never felt constrained by 1 GB yet, with
all multiple instances I'm usually running. Maybe in Solaris/Oracle
world you can get advantage of extra memory, but, not being a
professional in that area, I can't comment on it.

It has actually. I have a full copy sitting next to me. Check MS's
website as well, it is no longer in beta. Some people have said that
MS just waited till Intel had x86-64 products out, but I rather doubt
that's the only reason. Certainly with AMD's volume alone, there was
less impetus to do so, but MS does also take a while to port and QA
their products.

You can get win64...I don't much about MSSQL, but everything you've
said sounds reasonable (won't port 2000, 2005 is still too new). I
think people will migrate to '05 if they see rather substantial
benefits.
