The FeiTeng (飞腾, fēiténg) is a computer central processing unit designed and produced in China.[1]

It is manufactured with 65 nm technology and contains 350 million gates. Its clock frequency is 0.8–1 GHz. It is compatible with SPARCv9 instruction set architecture.[2]

Each chip contains 8 cores and is capable of executing 64 threads. There are 3 HyperTransport channels for coherent links, 4 DDR3 memory controllers and a 8x PCIe 2.0 link. [3]

The Tianhe-1A supercomputer uses 2,048 FeiTeng 1000 processors.[4] Tianhe-1A has a theoretical peak performance of 4.701 petaflops.[3][5] The FeiTeng-1000 is an eight-core processor based on the SPARC system and is used to operate service nodes on the Tianhe-1.[1][3]

It has been speculated that FeiTeng used the work of the OpenSPARC project.[6]

FeiTeng is third generation CPU from the YinHeFeiTeng (银河飞騰, YHFT) family. This CPU family has been developed by team directed by NUDT Prof. Xing Zuocheng.[7] The first generation was an EPIC CPU, binary compatible with the Intel Itanium 2. The second generation, the FT64, was a system on a chip with CPU and 64-bit stream processor. FT64 were used in YinHe (银河) supercomputers as accelerators.[8]
