Earlier this year, we covered the raising phenomenon of Chinese CPUs in quite a detail, including the main high end lines of Loongson (MIPS) and Shenwei (Alpha), as well as over a dozen of ARM licensees there. Then there was Icube with their UPU, a truly fused CPU plus GPU at the core and register level.
There's more to it: at the high end front, besides the academic-government MIPS and purely military, for now, Alpha, our friends in the north also developed their own Fengtian SPARC compatible processors. For now, these are not used as the main CPUs, but as I/O processors in some large supercomputers to help manage the ultrafast interconnects, twice the Infiniband QDR speed, that the country uses in their largest machines such as Tianhe. These interconnects have the SPARC CPU to manage the general I/O, and a NPU, network interconnect processor, with most of the protocol overhead hardwired. Therefore, the main Xeon or other CPUs in the cluster don't need to be bothered handling the interconnect I/O overhead, raising the total real system performance.
