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 microarchitecture 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 be pairing up with Tylerburg chipsets. EP stands for Efficient Performance, one of the new naming for the server platforms for energy efficency on 1-2 processor sockets. There are also Mission Critical (MC) for best RAS from 2-512 processor sockets, Expandable (EX) for RAS from 2-32 processor sockets as well as Entry (EN) on 1-2 processor sockets to better align with future IT usage.
