Forget GPUs — China unveils 2 ExaFLOPS supercomputer using only CPUs, packing 47,000 processors into 92 compute cabinets as it looks to supersede the US once again

National Supercomputing Center in Shenzen.

• Lingsheng system targets two exaFLOPS using only central processing units
• CPU-only architecture challenges GPU-dominated supercomputing industry standards
• System design integrates high-bandwidth memory and high-speed interconnect networks

A Chinese supercomputing center has announced plans for a machine that would reach two exaFLOPS using nothing but central processors.
