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.

Xeon E3-1220 3.10GHz 8MB 4 / 8 Yes / Yes 80W $189

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.

    Well, some of the customers I work with have some very specific work load. They do research and development and for them it is worth to have the best performance when they buy the system…

    About price, yes and no, as with 64 memory slot you can get a good price per gigabit compared to a system with only 18 slots or so if you need around 256GB or more memory. So there it can be good, but again specific.

    But you are right, for most Virtualization system I would rather go with 2U system like the Dell R710 who fit a good balance of CPU power and memory options at a better price. You can have them redundant so you can lose one or more to distribute your loads.

    Our company is planning to buy a couple of blades but they have the older generation x56xx cpus. I hope that they have this available soon. Reply

    i'd like to see 3d benchmark performances....

    it should be awesome !
