China Tests CPU-Only Supercomputer to Surpass US HPC Leader Amid GPU Restrictions (xataka.com)

• LineShine claims >2 exaflops using only LX2 CPUs
• LX2 processor: 304 cores, Armv9, HBM+DDR5 memory
• US GPU restrictions force China to innovate CPU-based HPC

"China is deploying a CPU-only supercomputer, LineShine, at the Shenzhen National Supercomputing Center to circumvent US export restrictions on advanced GPUs. The system uses 47,000 domestic LX2 Armv9 CPUs and claims over 2 exaflops, potentially surpassing the US El Capitan (1.8 exaflops). While driving digital autonomy, the architecture may be less efficient than GPU-based systems for AI workloads."
