Not saying this is a repost, because clearly there are no other Dunnington dedicated threads atm, but just so folks are aware there is a sizable amount of discussion on Dunnington in the following thread: (which is probably why it hasn't got its own thread to date)

The Dunnington CPUs are based on Penryn 45nm architecture and will feature 16MB of L3 cache, and will be compatible with current Tigerton Socket 604 motherboards. The processors are business-class pieces of silicon and not aimed at the consumer market (Intel currently has no plans to release a mainstream six-core CPU). The 7400-series will be Intel?s first monolithic CPU that puts more than two cores on a single piece of silicon.

i totally forgot about that thread

Oops, sorry. I'll lock this one up. didn't realize the content of the other thread.

Keep it?

Lock it?

Thanks, Keys.

I think we need a thread that at least has what they are talking about in the thread title. The other one got a little off-topic.

I say keep this one.

I'm with Mark, Keys I think this thread should stay.

My point of adding the link was merely to make sure that future thread readers had the opportunity to read some more information from Viditor and Phynaz in the event it doesn't get duplicated in this thread in the meantime.

Wasn't trying to imply that this thread needed to go away, please keep.

Thread related question - why wouldn't Intel also release this puppy as a top-of-the-line XEON on LGA775 or LGA771?

Not saying to purchase it as an enthusiast as clearly it would be priced around $2.5k-$3k, but I am baffled by the fact Intel restricted the release to just the socket 604 XEON platform.

You think they are worried about Dunnington undermining an effort to get Gainestown into a momentum situation?

Seems to me they could sell quite a few Dunnington's to the dual-socket LGA771 install base as an upgrade cycle for their existing Harpertowns in a year or two. But maybe they'd rather that revenue went to Westmere instead, although the same could be said about releasing this chip for socket 604 systems instead of getting those folks to upgrade to Nehalem Xeons.

Dunnington is the true successor to Tulsa, the Netburst based Xeon MP CPU with 16MB L3 cache. Historically, large last level cache MP Xeons always came around a year later than the DP Xeons and the smaller cache versions(which are basically desktop chips with server grade validation).

Tigerton chips are really no different than a Yorkfield. It contains same amount of cache/cores/transistors. Dunnington actually makes an effort to put large, shared L3 cache for scability for 4+ CPU systems, and are aimed as such.

Nehalem versions won't come until late 2009/early 2010 with Beckton, which makes it close to Westmere's release.

It's possible that Intel intends to "segregate" it's desktop and server CPU's like they used to. I could enable them to place higher margins on the Xeon chips if they only sell to corporations IT infrastructures. In the end though, the only difference between a desktop CPU and Server CPU was the ability to have 2 or more CPU's in a system, and maybe difference amounts of cache. Yes, I am rambling.

 

[Idontcare]

Not rambling, clearly they do that with their Itanium line. You think they are looking to further drive a segment distinction for their XEON processors between the 2S vs. 4S with harpertown vs. Dunnington? Plausible, clearly they are doing it in effect.
