Outgrowing the known lineup of 32 nm client processors (under the Core family), Intel's upcoming lineup of processors based on the 32 nm Westmere architecture will comprise of no less than 13 models under the Xeon E5000, L5000, X5000, and W3600 series. Among these, there are six hexa-core Xeon processors, including X5680 (3.33 GHz), X5670 (2.93 GHz), X5660 (2.80 GHz), and X5650 (2.66 GHz). X5680 has a TDP of 130W, with the latter three sub 3 GHz models having TDP as low as 95W. There is an energy-efficient L5640 hexa-core model clocked at 2.26 GHz, with TDP at 60W, and a single-socket W3680, clocked at 3.33 GHz with 130W TDP. All these models have six cores, and 12 MB of L3 cache.

Next up, are Intel's first 32 nm quad-core processors: Xeon X5677 (3.46 GHz, 130W), X5647 (3.06 GHz, 95W), E5640 (2.66 GHz, 80W), X5630 (2.53 GHz, 80W), X5620 (2.40 GHz, 80W), and energy efficient L5630 (2.13 GHz, 40W), and L5609 (1.86 GHz, 40W). Except L5609, all these quad-core chips have HyperThreading Technology and Turbo Boost available. The L2 cache amounts for each of these chips is unknown as of now, but should be up to 8 MB, or as low as 4 MB for some models. Most of these chips are slated for release on March 16, 2010.
