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.

quiksilvr - Wednesday, April 6, 2011 - linkImbecile.
Moving on, I like seeing Intel push forward, but those prices are quite high.
mariush - Wednesday, April 6, 2011 - linkI'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.
MySchizoBuddy - Thursday, April 7, 2011 - linkAMD has 16 core processors? when did that happen
MrSpadge - Sunday, May 1, 2011 - linkHe may be referring to the coming Bulldozers with 6 and 8 modules.
H8ff0000 - Wednesday, April 6, 2011 - linkShouldn't this be a ban-able offense on every forum / comment-enabled website? Childishness abounds.
tipoo - Wednesday, April 6, 2011 - linkIt should be.
taltamir - Thursday, April 7, 2011 - linkI concur
