Hygon

Hygon described its C86-5G server processor, with 128 cores, 512 threads and over 15% better per-clock performance, saying it is in mass production. It also introduced four infrastructure chips, including a 104-lane PCIe 5.0 switch and a scale-up switch for linking accelerators, plus a 400 Gb/s ScaleFabric network.

• C86-5G: 128 cores, 512 threads (4 per core), up to 10 TFLOPS FP64.
• 104 PCIe 5.0 lanes and AVX-512 support.
• Scale-up interconnect switch positioned like Nvidia's NVLink.
• ScaleFabric: 400 Gb/s with 0.93-microsecond latency.
