Socket FM2
General Info
IntroductionOctober 1, 2012 (launched)
TDP100 W
TypeOrganic Micro Pin Grid Array
Dimension40.0 mm × 40.0 mm
Pitch1.27 mm
NameSocket FM2

Socket FM2 was the socket for OPGA-904-packaged AMD desktop microprocessors with integrated graphics, the successor to Socket FM1. Its counterparts for mobile processors are Socket FS1r2 and the FP2 package. Socket FM2 was superseded by Socket FM2+.

Socket FM2 was used in AMD's "Virgo" platform. All processors for Socket FM2, codename "Trinity" and "Richland", are members of AMD's Family 15h with CPU cores based on the Piledriver microarchitecture, and were fabricated on a 32 nm SOI process.

Socket FM2 has the same dimensions as Socket FM1 but the processor package for Socket FM2 is mechanically, by omitting different key pins, and electrically incompatible with Socket FM1 and vice versa.
