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
LGA 1156 (land grid array 1156), also known as Socket H or H1, is an Intel desktop CPU socket. Its incompatible successor is LGA 1155.
The last processors supporting it ceased production in 2011.
