Given the explosive demand for ai chips it should surprise no one that companies that have invested a lot into cuda needs more Nvidia gpus. A lot of people interpret this as china needing Nvidia and can't live without it. When reality is that these companies need Nvidia right now because they will fall behind the ai race to Huawei if they don't keep buying Nvidia gpus .A800 might still be a competitive chip in both 2023 and 2024 but probably would be obsoleted by 2025. The question is what are these Chinese giants are going to do by then. Are they even actively seeking and improving domestic alternatives to replace Nvidia chips.
Longer term, you probably end up with a cuda vs ascend battle in china.
