'''Godson-2H''' ('''龙芯2H''') 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 late-[[2010]], the Godson-2H operates at up to 1 GHz consuming up to 10 W. This chip was manufactured on [[STMicroelectronics]]' [[65 nm process]].
 
 
 
The Godson-2H is actually a complete [[system on a chip]] incorporating the [[northbridge]] along with the [[southbridge]] on-die. Additionally the Godson-2H also incorporates a low-power [[Vivante]] {{vivante|GC800}} [[IGP]] operating at 400 MHz.
 
 
 
In addition to a standalone SoC, the Godson-2H can also operate in slave-mode serving as a cooperative [[southbridge]] to the more powerful {{\\\|Godson 3}} multi-core processor family.
