Lynnfield is the code name for a quad-core processor fromIntel released in September 2009.[1] It was sold in varying configurations asCore i5-7xx,Core i7-8xx orXeon X34xx. Lynnfield uses theNehalem microarchitecture and replaces the earlierPenryn basedWolfdale andYorkfield processors, using the same45 nm process technology, but with a new memory and bus interface. The product code for Lynnfield is 80605, its CPUID value identifies it as family 6, model 30 (0106Ex).
Lynnfield is related to the earlierBloomfield andGainestown microprocessors, which are used in server and high-end desktop systems. The main difference between the two is Lynnfield's use of theLGA 1156 processor socket as opposed to theLGA 1366 socket used by Bloomfield and Gainestown processors. LGA 1156 processors includeDirect Media Interface andPCI Express links, which Intel has previously connected to the processor with a dedicatednorthbridge chip, called thememory controller hub orI/O hub.
The Lynnfield series of processors does not include built-in Intel graphics.
Themobile version of Lynnfield isClarksfield. Thedual-core version was going to beHavendale, but it was cancelled in favor ofClarkdale.
