阿里云否認大規模采購寒武紀思元370芯片傳聞

   時間:2025-09-01 14:13 來源:ITBEAR作者:任飛揚

近期,有市場傳言稱,由于英偉達H20芯片遭遇“安全”質疑,國內AI巨頭阿里巴巴旗下的阿里云為應對需求,大量采購了寒武紀的思元370芯片,數量高達15萬片。這一消息引發了業界的廣泛關注。

然而,阿里云相關負責人迅速對此進行了澄清,表示阿里云確實支持國產供應鏈,并采用了“一云多芯”的戰略,但關于采購15萬片寒武紀GPU的傳聞并不屬實。這一回應讓傳言的風波暫時平息。

據悉,思元370芯片是寒武紀的一款基于7nm制程工藝的重要產品,它首次采用了chiplet(芯粒)技術,集成了高達390億個晶體管,最大算力可達到256TOPS(INT8),性能相較于前代產品思元270有了顯著的提升。

不過,值得注意的是,思元370并非寒武紀最新的產品。目前,寒武紀已經推出了更新一代的訓練/推理一體芯片——思元590。這款芯片同樣采用了7nm+ Chiplet技術,但在性能上有了更大的飛躍,INT8算力高達512TOPS,是思元370的兩倍,同時支持千億參數的大模型訓練。FP16算力也達到了256TFLOPS,能效比優異。

從這一角度來看,如果阿里云真的需要采購寒武紀的AI芯片,更有可能選擇的是性能更為強勁的思元590,而非已經屬于老一代產品的思元370。

另一方面,有消息稱阿里巴巴正在自主研發一款新的人工智能芯片,旨在填補英偉達在中國市場的空白。這款芯片目前正處于測試階段,主要針對廣泛的AI推理任務,并且與英偉達的架構保持兼容。這一消息無疑為業界帶來了新的期待。

與此同時,寒武紀的股價近期也表現出強勁的增長勢頭。截至8月28日,寒武紀的股價大幅上漲15.73%,收盤價高達1587.91元/股,成功超越了貴州茅臺的收盤價1446.1元/股,成為A股市場最昂貴的股票之一。其總市值也隨之突破了6643億元大關,展現了市場對寒武紀未來發展的高度認可。
