China's LineShine supercomputer dethrones US' El Capitan, secures first place in Top 500 list — first machine in the rankings to sustain more than 2 ExaFLOPS of double-precision performance using only CPUs
… While an Armv9 CPU with SVE/SME can accelerate FP16/BF16/INT8 workloads, its mixed-precision uplift remains limited compared to systems with accelerators due to many reasons, including memory bandwidth, software maturity, and interconnect efficiency. …
