Considering that AMD’s ACP numbers are rather optimistic and Intel’s TDPs are rather pessimistic, the 8-thread quadcore 1.86 GHz L3426 ($284) makes the six-core 1.8 GHz Opteron 2419EE look expensive ($989). The former can push it’s clock up to 3.2 GHz under single threaded loads, and is thus a really interesting option if your application has a significant part of non-parallel code.
5. The "competition offers better per core and per chip performance" comment also ignores the fact that Magny-Cours is coming out with far more cores per chip than anything Intel has and a 12-core Magny-Cours will offer better performance per chip than a 6-core Westmere in multithreaded server applications.

Besides currently a single Xeon has no problems keeping up with a 2P Opty system so unless Istanbul increases IPC as well as core count Nehalem EX wont have that much trouble considering it will have 4x QPI and Quad DDR3 to enhance that memory loving server setup.

And a comment from MU which is very valid..

What is he basing all these ideas on? Nehalem-EX is huge, hot and hungry. It had better be extremely powerful. Better performance/watt than MC? I seriously doubt it in the majority of cases, but then again if you start out believing ACP is 'optimistic' and intels TDP is 'pessimistic' (seriously how much garbage is that? Intel downplaying their TDP? :lol: ), then sure you're gonna believe that Nehalem-EX is going to win on perf/watt. Kinda difficult to get over that initial bias, and the wording used in much of that caused a lot of consternation
It never fails to amaze me. You really do believe that every single thing intel releases is some kind of wonder miracle chip don't you? :lol:
Now I'm not saying Beckton is Larrabee, far from it. But it's quite close to Fermi I'll wager, and by that I mean too big, too hot and possibly too late. I wonder why we never see any Anandtech articles about that.

Unlike Istanbul which is just adding more cores or MC which is MCM (I still find it ironic that AMD laughed at Intel for the same thing yet here they are doing it........) of 2 Istanbul cores, Beckton adds more cache per core, increaded memory channels and much faster interconnects.
With all that I can say that I am pretty sure that a Beckton based server chip will have no problems going up against a MC chip. It wasn't to long ago that it would take near 2 Xeons in to compete with 1 Opty in certain situations, so why is it hard to believe that a 8 core CPU might be able to one up a 12 core CPU? Oh wait its Intel.......
As for its release, Intel never specified an exact date for its release. They said late 2009 or early 2010 and so far its still set for 3 months from now.
And remember, AMD was late with K10. By a lot. Being late doesn't mean anything. I do love your insider info though. You somehow know more about Beckton than anyone else, even review sites, and know that MC will be cheap. If its not.............
Meh.
