'''Godson-2F''' ('''龙芯2F''') is a {{arch|64}} [[MIPS]] performance processor developed by [[Institute of Computing Technology of the Chinese Academy of Sciences|ICT]] and later [[Loongson]] for desktop computers. Introduced in mid-[[2008]], the Godson-2F operates at up to 800 MHz consuming 5 W. This chip was manufactured on [[STMicroelectronics]]' [[90 nm process]].

The Godson-2F features a faster memory controller (supporting up to DDR2-667) and integrates some of the functionality of the [[southbridge]] including a PCI-X controller and more general-purpose I/O pins.
