Intel Targets 32-Core Processors in 2010

For servers, so they are plausible.
The world’s main supplier of microprocessors, Intel Corp., plans to offer a central processing unit for servers, which will be 15 times faster compared to today’s chips and which will contain up to 32 processing engines, according to a media report. The processor code-named Gulftown will have “eight processing nodes” with four cores on each one, according to TG Daily web-site, which may mean that the chip will consist of several physical dice. Every die will sport four processing engines, 3MB unified level-three cache, while every core will have 512KB L2 cache. The dice will be connected to each other using “a ring architecture” interconnect technology.

That's nice, how fast is it going to go? Since 3Ghtz just an't cutting it and multiple core software is still being worked on.
As it stands my AMD64 4800 X2's second CPU is not being fully used as it is, prehaps 30% of my second CPU's power is being used. How little benfit are we going to see after we start talking 10+ CPU's.
The only time I see both being used fully is with SETI and other similar style crunchers. I only see moderate benfit with day to day tasks(Computer responds faster) and only a slight benfit with gaming.

For the desktop, maybe. Server workloads often (but not always) are multithreaded.

Depends on the workloads.

Webserving often benefits from more cores. Did you even read the article and its referencing to server workloads?

Yes it references servers, that never stoped people for using server CPU's for home systems. And keep in mind that server markets(At least where Intel is concerned) have always been bigger more powerful Desktop CPU's. Thus for the top in preformance, people have gotten server CPU's for home systems.
Unless you wish to suggest that Intel won't go this way with it's desktop cpu's as well(IE multiple, multiple cores).

IMHO 3 GHz is cutting it with the new improvements in Intel's lineup. The fact that a 2 GHz Core Single AFAIK is similar in performance to a 3 GHz Pentium 4...and that's Yonah...a dual core 3 GHz Conroe, Merom, or Santa Rosa sounds quite nice.
I expect Windows Vista will have better SMP support than Windows XP, so I'm sure it'll be used. IIRC Linux and Mac OS X alread have support for that many processors.
And by 2010, most if not all of our software will be multithreaded. Except for legacy stuff.

Itanium is hardly a bigger and more powerful desktop CPU. The server varients of Core (NGMA) also scale to more cores then their desktop counterparts.

Who? I don't know many performance enthusiasts running Xeon or Opteron (S240) machines.

They will, but maybe 2-4 way, not 32 on the desktop.

Windows XP Home has support for one physical processor (I'm guessing up to 2 cores is supported, perhaps even four). XP Pro has two-socket support; the server varients more.

He's talking about
actual server systems, not shit hobbyists can get their hands on to build a small web server. In the real server systems, you'll very frequently see 32- and 64-way configurations. Itaniums, Opterons and Xeons (nevermind the POWER or UltraSPARC series) aren't conventionally run on desktop systems, even in hobbyist circles.

Of course they'll gravitate toward more cores. But that doesn't mean that desktop systems are going to have 32-way systems in 2010.

I've heard of the very lowest end (1 way) Opterons being used in a hobbyist machine, due solely to the fact that it was cheaper than a Athlon 64, at the time. Never heard of anyone using Xeons or Itaniums.

Opterons and Xeons are basically just high-quality versions of Athlon and Pentium chips. The Itanium series is actually a completely different chip altogether.

Yeah, I use an Opteron 165 - the initial S939 Opteron pricing was very good until AMD realized they were undercutting their Athlon sales in the enthusiast market.

Still, Opteron (2XX and higher) and Xeon are not quite the same as their desktop counterparts.

Does anyone else want to see a water-cooled Core Duo at 5GHz???

What other differences are there? Besides more cache (IIRC the Xeons have buttloads of cache) and multi-processor support, that is.

Opteron's multiprocessor support comes from the addition of two extra HyperTransport channels and its memory controller is more sophisticated (supporting registered and ECC memory).
Xeon has varied throughout the years to being more-or-less a rebranded Pentium to having various changes here and there often to support multiple processor configurations. Newer Xeons, for example, have hardware virtualization support and the Xeon MP had quite a few extra features considered important to the sever market (a quick summary can be found
here)
