Huawei’s Ascend 910B AI chip has been found in some tests to deliver 80 per cent of the efficiency of an Nvidia A100 when training large language models, but “in some other tests, Ascend chips can beat the A100 by 20 per cent”, said Wang Tao, chief operating officer of Huawei Ascend and Kunpeng ecosystem, on the sidelines of the Nanjing World Semiconductor Conference on Thursday.
