据《华尔街日报》报道，这款晶片目前处于测试阶段，由中国企业代工生产，有别于阿里巴巴此前委托台 积电生产的AI处理器。 美国科技巨头英伟达在华销售持续受阻之际，美国媒体报道称，中国科技巨头阿里巴巴已研发一款新型晶片，比 以往版本更具通用性，可支持更广泛的人工智能（AI）推理任务。 H20是英伟达依据美国对华技术出口管制要求，特供中国市场的低配版AI晶片。美国特朗普政府曾在今年4 月叫停H20晶片对华出口，后于7月重启，随后以安全风险为由，要求企业暂缓采购相关晶片。 彭博社8月中引述知情者称，有关部门敦促本土企业避免使用H20晶片，尤其是跟政府相关的用途。 另一方面，阿里巴巴星期五（8月9日）公布的财报显示，得益于强劲的AI需求，公司云计算业务在4月至6 月的营收同比增长26%，超出市场预期。 阿里巴巴集团首席执行官吴泳铭说："面向未来，我们将围绕大消费和AI+云两大战略重心继续坚定投入， 把握历史机遇，实现长期增长。" 随着AI在中国加速普及，推理运算需求正急剧增长。知情者透露，阿里巴巴这款新晶片正是为推理任务设 计，而这类运算通常无需依赖最先进的晶片。 业内人士指出，距离生产出可与最先进美国晶片相媲美的产品仍 ...
