Westmere-EX SKUs and Performance
Intel has three general classifications for the new 10-core processors. The E7-x870 runs at 2.4GHz and has a 30MB L3, while the E7-x860 runs at 2.26GHz and the E7-x850 runs at 2.13GHz; the lower clocked models are also downgraded to a 24MB L3. As there are versions for 8-, 4-, and 2-socket servers, we get nine new SKUs. Pricing on the highest end 8-socket models is very high, but that's not too surprising for the target market: the E7-8870 costs $4616, the E7-8860 goes for $4061, and the E7-8850 comes with a "bargain" price of $3059. For quad-socket chips, you can knock that down about $225, and dual-socket chips will reduce prices another $175 or so.
What this means is pricing for the fastest Xeons has increased by about $1000, a clear sign that Intel does not expect any competition in the small but profitable high-end x86 market. And indeed, the current AMD "Magny-cours" is targeted at the midrange server market, not the high-end. Bulldozer will be AMD's attempt to take on these new Xeon models, and it probably won't attack this high-end market before the end of the year.
Also present is a low power E7-8867L, which runs 10 cores at 2.13GHz but needs 105W instead of the 130W of the E7-8850. For the 25W drop in TDP, the price jumps up to $4172.
The E7-8837 is another interestin processor. It has eight cores and forgoes Hyper-Threading, so it's like the Nehalem-EX but with a 2.67GHz clock it runs 18% higher than the fastest Nehalem-EX CPUs. Thus, it looks like the 45nm to 32nm transition either delivers two extra cores and a 6% clockspeed increase, or it improves clocks by 18% with the same number of cores. Below is the complete table of new SKUs.

Taken together, the two extra cores (up to 25% more performance) and a 6% clock increase, along with some subtle core improvements, mean the Westmere-EX parts should deliver 20-40% more performance within the same TDP. It's not enough to revolutionize the server space, but more performance per watt is nothing to sneeze at.

Imbecile.Moving on, I like seeing Intel push forward, but those prices are quite high.

I'd be happy to be just low enough to make AMD drop prices on their 12 and 16 cores processors.Hoping to be able to afford a 7-900$ quad G34 motherboard and 4 x 500-700$ 12/16 core processors in the near future.

AMD has 16 core processors? when did that happenMrSpadge - Sunday, May 1, 2011 - link
He may be referring to the coming Bulldozers with 6 and 8 modules.MrS
