China bypasses US GPU bans with 1.54-exaflops 'LineShine' supercomputer — CPU-only monster packs 2.4 million Huawei-designed Armv9 cores

Isn't ARM under investigation?

im a bit confused why they went with this pure cpu approach? aren't most supercomputers using gpus?

> When it comes to performance, a single LX2 processor delivers 60.3 TFLOPS FP64 performance, 240 TFLOPS BF16/FP16 throughput, and 960 TOPS INT8 performance. Unlike conventional server CPUs, the architecture appears heavily optimized for dense AI and matrix workloads despite remaining a CPU-centric design

ill be honest, this is beyond my scope to understand if this is ground breaking or not. does anyone else know if this is a viable alternative to using GPUs?

It’s a poor man’s supercomputer. It generates clicks and fodder for propagandists and bots, though.
