Intel has revealed some information on their Nehalem processor in the latest roadmap updates. The 45nm Hi-K Nehalem-EP is based on 4-issue Intel Core micro-architecture technology, supports Simultaneous multi-threading and Multi-level shared cache architecture (L2 and L3). Nehalem-EP processor will arrive earlier than expected, in H2 2008, and will pair up with Tylerburg chipsets. EP stands for Efficient Performance, one of the new naming schemes for server platforms. It should mean good energy efficency on 1-2 processor sockets. There are also Mission Critical (MC) markings, for best RAS from 2-512 processor sockets, Expandable (EX) is for RAS from 2-32 processor sockets as well as Entry (EN) on 1-2 processor sockets to better align with future IT usage.
