Sugon's 4th Generation Hygon processor uses AMD's latest SP5 packaging, according to a finding by hardware leaker YuuKi_AnS. A quick Google search reveals that the CPU resembles AMD's latest Zen 4-based processors in terms of memory and interface support. However, the Chinese company has likely just adopted new packaging to gain features like DDR5 memory support.
Apparently, Hygon has a processor called C86-7490, which is available on a Chinese online auction. The unit is slightly scratched, as can be observed in the picture. The package says that the product was 'Designed in Chengdu' and 'Made in China,' though this was the same with the first generation Hygon CPUs based on the Zen microarchitecture. While the silicon dies were made in the U.S. by GlobalFoundries, they supported China-specific SM3 and SM4 encryption algorithms disabled on AMD-badged parts and assembled in China, formally allowing Hygon to say that they were designed and made in China.
