FT4 is a BGA-769 package for low power AMD mobile microprocessors with an integrated north bridge, graphics processor, and controller hub. These SOCs are also available in the larger FP4 package. FT4 succeeded the FT3 and FT3b package and was superseded by the FT5 package.

All processors in the FT4 package, codename "Stoney Ridge", are members of AMD's Family 15h with CPU cores based on the Excavator microarchitecture, and are fabricated on a 28 nm SOI process.

The FT4 package has the same dimensions as the FT3 and FT3b package but is electrically incompatible with them.
