Cambricon Siyuan 590
The listed Chinese AI-chip champion riding domestic substitution.
You're looking at a chip record: what this processor is, its key specs, who designs, manufactures and supplies its parts, and where it gets used.
Cambricon, spun out of the Chinese Academy of Sciences and listed on Shanghai's STAR board, supplies training accelerators to Chinese clouds displacing banned NVIDIA parts. Its stock became one of China's most valuable semiconductor names in 2025 on substitution demand. Detailed specifications are not published; reported figures place the 590 series near A100-class performance.
