China's all-CPU LineShine supercomputer reaches exascale without a single Nvidia or AMD chip

China's National Supercomputing Center in Shenzhen has unveiled LineShine, a 2-exaflop supercomputer built entirely from Huawei's domestic LX2 processors , no Nvidia, no AMD, no foreign components. The machine demonstrates that US chip export controls may have accelerated China's push to build a fully sovereign AI compute stack, with implications for how infrastructure investment and geopolitical leverage will play out over the next decade.
