Yesterday, Intel announced that their flagship server processor, the Xeon Nehalem-EX, is being succeeded by the Xeon Westmere-EX, a process-shrinking " tick" in Intel's terminology. By shrinking Intel's largest Xeon to 32nm, the best Westmere-EX Xeon is now clocked 6% higher (2.4GHz versus 2.26GHz), gets two extra cores (10 versus 8) and has a 30MB L3 (instead of 24MB).
As is typical for a tick, the core improvements are rather subtle. The only tangible improvement should be the improved memory controller that is capable of extracting up to 20% more bandwidth out of the same DIMMs. The Nehalem-EX was the first quad-socket Xeon that was not starved by memory bandwidth, and we expect that the Westmere-EX will perform very well in bandwidth limited HPC applications.
Read on to learn more about the latest Xeon and the new server we are testing.
