BAD HARDWARE WEEK

Nehalem offers 300% performance per watt increase. Then, Intel's current core seems pretty pale compared to Nehalem envisioned in 2001. Because it though didn't reach 10,2 Ghz in 2005. And Nehalem push into H2 2008 (it was scheduled for 2009) might be a sign of forthcoming AMD rise.
However, Intel started with Nehalem development in 2002 and 6 years after that seems like a bunch of problems not completely resolved. Lets wait how Intel will do it. Intel's last all in one solution to all problems was well known under the name Prescott in 2004.
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. LGA1366 and LGA715 are used by Nehalem
