輝達CEO訪華:川普禁售晶片後




Nvidia行政總裁黃仁勳訪華 美國新禁令壓力下尋求中方合作

Nvidia CEO Jensen Huang delivers a keynote address at the Consumer Electronics Show (CES) in Las Vegas, Nev., on Jan. 6, 2025.

Nvidia(輝達)行政總裁黃仁勳本週現身北京,目的是在美國政府加強對AI晶片出口中國的限制之後,鞏固區域貿易關係。根據中國官媒報道,黃仁勳是應中國國際貿易促進委員會邀請到訪,並表達希望公司能夠繼續與中國合作的願望。

這次訪華正值美國特朗普政府宣布,對Nvidia唯一能在中國銷售、無需特別許可證的H20 AI晶片,實施新的出口管制。H20其實是Nvidia在2022年為配合拜登政府對華科技出口限制而特別開發的「閹割版」H100晶片。

Nvidia預計,這輪新限制會令公司在庫存和採購承諾上損失約55億美元。美國當局近年一直將Nvidia的AI晶片列為出口管制重點,目的是防止中國獲得最先進的AI技術,確保美國國家安全及在AI競賽中保持領先。

AI晶片出口管制升級 中國市場影響巨大

雖然H20的核心數量減少,性能有所降低,但依然具備AI推理(inference)等關鍵能力,即讓訓練好的AI模型能分析從未接觸過的新數據。這也引發外界關注,一旦大量採購H20,仍有可能用於打造超級計算機。

美國國會「中共特別委員會」最新報告就指出,中國AI公司DeepSeek曾利用3萬枚H20晶片訓練其知名聊天機械人,並且還下單購買數千枚,但新規實施後將無法再獲得這些晶片。

委員會主席John Moolenaar和資深議員Raja Krishnamoorthi本週致函黃仁勳,質疑DeepSeek能取得H20及其他受限晶片,部分原因可能是透過新加坡等鄰近國家走私流入中國。

報告又顯示,Nvidia來自中國的銷售比重,已由2021年的超過25%急跌至現時不足15%。然而,東南亞等地區的銷售有機會被轉售到中國,或流入二手市場。

因此,委員會要求Nvidia公開自2020年以來,所有購買超過500枚AI相關晶片的客戶資料,以及與DeepSeek相關的通訊紀錄。

美國本土生產AI超級電腦 Nvidia加速轉型

雖然Nvidia在中國的未來似乎不太樂觀,公司已宣布將部分最核心的生產能力轉移至美國本土。黃仁勳4月14日宣布,Nvidia首次會在美國生產AI超級電腦,並已於亞利桑那州和德州設立逾100萬平方呎的廠房和測試設施。

黃仁勳表示,未來四年Nvidia會在美國基建投資超過半萬億美元,並會有台積電等國際夥伴協助。

編輯評論:Nvidia的兩難與地緣科技戰的香港啟示

Nvidia近年一直在中美科技角力中走鋼線。今次黃仁勳訪華,既是公關動作,也是現實壓力下的必然選擇。當美國一再收緊AI晶片出口,中國市場對Nvidia來說既是巨大商機,也是潛在風險。從H20「閹割版」的設計到如今連這個也被封殺,反映美國對中國科技發展的防範已進入新階段。

值得注意的是,無論美國怎樣限制,技術流通和市場需求總會尋找縫隙——正如報告所言,東南亞成為「灰色通道」的可能性大增。這對香港企業和科技圈是一個警示:在全球供應鏈和監管環境日益複雜的時代,單靠一個市場或單一政策紅利,風險極高。另一方面,Nvidia轉向美國本土生產,也顯示西方在「去中國化」和本土化供應鏈上的決心。

香港作為國際科技和金融樞紐,面對這類地緣科技戰,既要靈活應對政策變化,更要加強自身創新能力,減少對單一技術來源的依賴。否則,一旦國際局勢再有變動,本地企業隨時會被捲入更深層次的科技冷戰。

最後,Nvidia這場中美之間的「晶片博弈」,其實也是全球AI產業未來格局的縮影。誰能在技術、政策和市場三方面取得平衡,才是真正的贏家。

總體而言,這張照片風格清新、甜美,光線柔和,突出了人物的時尚穿搭和外貌。 Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference) of a ultra-sharp studio portrait of a confident woman kneeling on the floor with her body slightly leaning back, her right hand gently touching her hair, and her left arm resting on her bent knee. She is dressed in a sleek, strapless black bodysuit that accentuates her figure, paired with elegant black patterned lace pantyhose that add texture and sophistication. She wears a pair of classic black high heels, elevating her posture and emphasizing her elongated legs. The background is a seamless, pure white studio backdrop, providing a clean and minimalist aesthetic that directs full focus to her form and attire. *** The lighting setup is soft, evenly distributed, with a diffused key light positioned to the left, casting gentle shadows that sculpt her contours and highlight the intricate lace pattern of her tights. The overall color palette is monochromatic, emphasizing blacks and whites to create a timeless, sophisticated mood. The composition is carefully balanced, capturing her from the waist up in a slightly angled pose that accentuates her curves and confidence. Use a professional camera with a 85mm or 50mm lens at wide aperture (f/1.8 to f/2.😎 for a shallow depth of field, ensuring crisp detail on her outfit and pose while softly blurring the background. Post-process minimally to enhance clarity, contrast, and natural skin tones, maintaining a polished, elegant, and modern aesthetic suitable for fashion or editorial photography. {
