Lynnfield (microprocessor)
Encyclopedia
Lynnfield is the code name for a quad-core processor from Intel released in September 2009. It is sold in varying configurations as Core i5-7xx, Core i7-8xx or Xeon
X34xx. Lynnfield uses the Nehalem microarchitecture and replaces the earlier Penryn based Yorkfield
processor, using the same 45 nm process technology, but 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 earlier Bloomfield
and Gainestown microprocessors, which are used in server and high-end desktop systems. The main difference between the two is Lynnfield's use of the LGA 1156
processor socket as opposed to the LGA 1366 used in the others. LGA 1156 processors include Direct Media Interface
and PCI Express
links, which Intel has previously connected to the processor with a dedicated northbridge
chip, called the memory controller hub or I/O hub.
The mobile version of Lynnfield is Clarksfield

Direct Media Interface
The Direct Media Interface is the link between an Intel northbridge and an Intel southbridge on a computer motherboard. It was first used between the 9xx chipsets and the ICH6, released in 2004. Previous chipsets had used the Hub Interface to perform the same function. Server chipsets use a...

The northbridge has historically been one of the two chips in the core logic chipset on a PC motherboard, the other being the southbridge. Increasingly these functions have migrated to the CPU chip itself, beginning with memory and graphics controllers. For Intel Sandy Bridge and AMD Fusion...
