原文內容:
根據人工智慧(AI)軟體業者MosaicML的最新評測報告,超微(AMD)AI晶片目前的效能
約是輝達(Nvidia)產品的80%,但未來有望迎頭趕上。
路透報導,輝達支配了強大AI晶片的市場,這類晶片驅動了聊天機器人ChatGPT等AI服務
,在近幾個月席捲科技產業。AI熱潮刺激輝達的市值衝破1兆美元,也使其晶片產品供不
應求,輝達說,正試圖解決這項問題。在此同時,科技業者正找尋替代品,寄望超微能成
為輝達有力的對手。這促使MosaicML評比了超微和輝達的AI晶片。
MosaicML檢視了超微的MI250和輝達的A100,這兩款晶片雖是兩家大廠當前旗艦晶片的上
一代,但需求仍相當火熱。
MosaicML發現,MI250能達到A100的八成效能,主因是超微去年底發布了軟體更新,以及
Meta Platforms支援開發的新版開源軟體PyTorch也在今年3月發表。
MosaicML科技長湯漢林(Hanlin Tang)認為,超微如果按目前進度進行後續的軟體更新
,未來可望讓MI250的效能與A100平起平坐。
湯漢林表示:「就多數(機器學習)的晶片業者來說,軟體是最大罩門。超微以往的強項
就是軟體層面。」他補充說,MosaicML這次的研究並未收受超微的資金。
湯漢林指出,MosaicML採用自家的工具、PyTorch及超微的軟體來訓練大型語言模型,也
不必更動這些軟體的程式碼庫。
他說,若開發商能用合適的價格採購超微晶片,「可以今日就採用這些晶片,因為它們與
輝達的產品可以相互替換。」
MosaicML表示,這項研究是為了證明,除了輝達晶片以外,還有其他選擇。
超微在聲明中表示,這項研究結果「讓我們的策略更具說服力,即支持開放、易於執行的
軟體生態系統,用於超微硬體上的AI訓練和推論」。
心得/評論:超微與輝達這兩家晶片彼此追趕,舊有CPU大戰,現有GPU大戰
研究者認為超微在有強大的軟體技術,效能就有望追上輝達。
這兩家晶片效能比拚,對AI的發展是件好事。
