FP4 is a BGA-968 package for AMD mobile and embedded microprocessors with an integrated north bridge, graphics processor, and controller hub. Some of these SOCs are also available in the smaller FT3b and FT4 BGA packages and in PGA packages for Socket FM2+ and Socket AM4. FP4 is the successor to the FP3 package and was superseded by the FP5 package.

Processors in the FP4 package are members of AMD's Family 15h with CPU cores based on the Excavator microarchitecture, and Family 16h with Puma cores. All these processors are fabricated on a 28 nm SOI process.
