Intel Launches Xeon E3 & E7 "Westmere EX" Processors

Intel has presented more than twenty new Xeon processors which the semiconductor company hopes will allow it to compete even more effectively with the big iron RISC server makers.

The E7 is targeted at data centers and is designed, as for all server chips, for mission-critical applications. Compared to the previous generation, that range now supports up to 2TB DDR3 memory and supports low voltage DIMM modules.

The top of the range E7-8870 model is clocked at 2.4GHz with 30MB cache, a TDP of 130W, 10 Cores (or 20 threads), support for Intel's Turbo Boost and Hyper Threading and will target eight-socket servers.

The product comes with a 1kU price of $4616, the most expensive of the 18 E7 Xeon processors launched. The other E7 model of interest is the E7-4807 which runs at 1.86GHz and a TDP of 95W with six cores and 18MB cache.

At the other end of the spectrum is the Xeon E3 which unsurprisingly has a rather high starting clock speed, going from 2.2GHz to a whopping 3.5GHz. We suspect that the E3 range will target single-core servers and workstations; of particular interest is the low voltage, low TDP E3-1260L which comes with four cores and a TDP of 45W and the E3-1220L which is clocked at 2.2GHz, comes with two cache and a TDP of only 20W.

Intel is also integrating some smart security features like new instructions for the Advanced Encryption Standard and its own Trusted Execution Technology.
