The process node used to fab the chip and the name of the foundry have not been disclosed.
In the past Hygon co-designed its processors with AMD and the C86-5G is the first one to be designed with a Hygon proprietary micro-architecture.
The chip has up to 128 cores and 512 threads enabled by four-way simultaneous multithreading (SMT4) technology which allows each core to handle four threads simultaneously.
It supports 16 channels of DDR5-5600 memory, enabling up to 1TB of RAM using current standard DDR5 modules, suitable for large enterprise and datacentre workloads.
It supports advanced instructions including AVX-512, which are valuable for AI, analytics, and scientific computing workloads requiring heavy vector processing and has an integrated cryptographic co-processor.
The processor features support for CXL 2.0 and offers a large number of PCIe lanes (128 lanes of PCIe 5.0 on the predecessor, and similar or better expected in the C86-5G), ensuring high bandwidth for accelerators, NVMe storage, and networking.
It’s designed for enterprise servers, AI training clusters, large-scale analytics, and virtualised environments
Hygon was bought in May by the Chinese supercomputer Sugon which spun off from the Chinese Academy of Sciences.
