Jump to: navigation, search Intel CPU core roadmaps from NetBurst to Sandy Bridge Nehalem is the codename for an Intel processor microarchitecture,[1] successor to the Core microarchitecture. The first processor released with the Nehalem architecture is the desktop Core i7,[2] which was released on November 15, 2008 in Tokyo and November 17, 2008 in the USA.[3] The first computer to use Nehalem-based Xeon processors was the Mac Pro workstation announced on March 3, 2009.[4] Nehalem-based Xeon EX processors for larger servers are expected in Q4 2009.[5] Mobile Nehalem-based processors will follow in 2010. Initial Nehalem processors use the same 45 nm manufacturing methods as Penryn. A working system with two Nehalem processors was shown at Intel Developer Forum Fall 2007,[6] and a large number of Nehalem systems were shown at Computex in June 2008. The architecture is named after the Nehalem River in Northwest Oregon,[citation needed] which is in turn named after the Nehalem Native American nation in Oregon.[citation needed] The code name itself had been seen on the end of several roadmaps starting in 2000. At that stage it was supposed to be the latest evolution of the NetBurst architecture. Since the abandonment of NetBurst, the codename has been recycled and refers to a completely different project.
