百度AI芯片部門崑崙完成了新一輪融資

uSMART盈立智投3月15日消息,據IFR報道,百度正在考慮將其人工智能芯片設計能力商業化,目的是讓崑崙成爲一家獨立的公司。百度AI芯片部門崑崙的新一輪融資是由中信產業基金領頭,其他投資者包括IDG資本、君聯資本和Oriza Hua,融資規模據猜測約爲20億美元。

百度3月12日起在香港招股,綜合多家券商數據,百度目前孖展暫錄375.4億港元,超額認購25.8倍。

2018年的百度AI開發者大會上,李彥宏宣佈百度將推出自研AI芯片崑崙,2019年12月,百度和三星宣佈,百度首款用於雲計算和邊緣計算的崑崙1代AI芯片已經完成研發,2020年12月17日,百度首席技術官王海峯透露,百度崑崙1量產已超過2萬片,並實現了應用部署,預計崑崙2將在2021年上半年量產。

從技術來說,崑崙1代處理器採用14nm工藝,16GB HBM先進內存,提供高達512GB/s的內存帶寬。在低於150瓦的功率下能夠實現256TOPS的INT8處理能力,以及每秒260萬億次定數運算性能。而作爲對比,英偉達開發的V100S芯片,其計算能力爲130TOPS的INT8;寒武紀同期推出的思元270,算力128TOPS的INT8 ,可見崑崙1代處理器性能確實是在一流水平上。

基於此芯片,百度推出了兩款AI加速卡,K100和K200,由於採用標準PCIe Gen4接口,兩款加速卡可被安裝在不同類型服務器、小型工控機和邊緣設備上,其高效能功耗比使雲端計算高密度以及智能邊緣穩定同時成爲可能,而崑崙1代AI芯片的表現相比英偉達T4更加穩定,且延遲也有優勢,被應用於大型服務器集羣當中。
目前,關於百度芯片量產的數據並不多:
l 崑崙1已經量產超過2萬片,在百度搜索引擎和百度智能雲生態夥伴等場景廣泛部署,應用在互聯網、工業製造、科研、智慧城市、智能交通等領域。
l 崑崙2將於2021年上半年實現量產,其性能比崑崙1再提升3倍。
