Chinese chipmaker readies 128-core, 512-thread CPU with AVX-512 and 16-channel DDR5-5600 support

Hygon CPU.

You won't typically find a Hygon processor among the list of best CPUs for gaming or other applications. Nevertheless, Hygon stands as one of China's most important fabless semiconductor companies. Hardware investigator HXL recently shared an ambitious roadmap detailing Hygon's forthcoming initiatives, including a flagship 128-core, 512-thread processor.

Baptized as the C86-5G, the upcoming server processor will feature up to 128 cores with simultaneous multithreading (SMT). However, there's a slight twist. Instead of utilizing the typical two-way SMT (SMT2) that we've grown accustomed to on modern mainstream and server chips, the C86-5G leverages four-way SMT (SMT4), which means four threads per core. That's why the C86-5G has 128 cores and 512 threads.
