特朗普擬再限Nvidia售AI芯片予中國




特朗普可能收緊對中國Nvidia銷售的限制 — 報導

根據報導,美國總統特朗普正在考慮對Nvidia向中國銷售AI晶片的限制進行加強,這一決定是基於最近DeepSeek的R1模型發布後所引發的後果。

根據彭博社的報導,特朗普政府正在考慮禁止向南太平洋國家出口Nvidia的H20 AI處理器。

Nvidia的H20晶片是Nvidia H100處理器的較慢版本,專為中國市場設計,以符合現行的美國制裁和規定。

如果特朗普政府確實加強對高性能計算晶片和半導體的出口限制,這將是自2022年以來美國政府第四次實施此類控制。

更嚴格的限制可能意味著Nvidia的利潤減少,並可能侵蝕美國在AI領域的全球市場份額。

在DeepSeek的R1模型發布後,Nvidia的股價遭受了重創。

美國對中國的出口管制反效果明顯

自2022年10月禁止向中國銷售Nvidia H100處理器以來,中國轉向國內企業,利用較弱的半導體和AI晶片的組合進行研究和開發AI。

這項研究的目標是減少對單一來源的AI晶片的依賴,並降低供應鏈風險。

在2023年6月,拜登政府宣布計劃對中國的AI晶片出口實施更嚴格的限制,這一政策在2023年10月由美國商務部工業與安全局採納。

2023年的限制擴大至包括在2023年更新之前符合規範的修改版AI處理晶片和半導體硬件。

儘管控制措施加強,與國家有關的中國實體仍然通過雲計算平台如亞馬遜網絡服務繞過美國制裁,獲取禁用的AI硬件。

中國的國有企業通過使用空殼實體或中介,間接獲取雲計算能力,而不是直接通過亞馬遜網絡服務。

對出口管制的批評者表示,這些措施以國家安全為名,降低了美國企業的競爭力,並且無法有效阻止其他國家獲取AI計算能力。

評論

特朗普政府在AI晶片出口上加強限制的舉措,無疑是基於國家安全的考量,但這樣的政策是否真的能夠有效保護美國的技術優勢,卻值得深思。過去的經驗顯示,對中國的出口管制不僅未能阻止其技術進步,反而可能刺激了中國在半導體和AI領域的自主研發。

此外,這種政策的實施可能會使美國企業面臨更大的市場挑戰,因為中國企業將會更加積極地尋找替代方案,甚至可能在未來的競爭中超越美國。這種情況下,美國是否能夠在全球市場中保持其主導地位,將成為一個重要的議題。

未來,特朗普及其政府需要更加謹慎地考慮這些措施的長期影響,並尋求更加平衡的策略,以確保國家安全的同時,也不損害美國企業的競爭力。

Create a photorealistic and highly detailed image featuring the attached image walking confidently down a modern city street, accompanied by Jason Statham, Dwayne “The Rock” Johnson, and Jason Momoa acting as bodyguards.
John Wick (Keanu Reeves) is walking just beside or slightly behind the subject, holding an umbrella over him to shield from light rain.
The subject should be the central figure, wearing stylish casual clothing — like a fitted jacket, dark jeans, and sunglasses — exuding calm authority and cool charisma.
Statham, The Rock, and Momoa are dressed in black tactical-style suits, maintaining alert, protective stances, scanning the surroundings like professional bodyguards. John Wick wears his signature black suit and tie, looking composed as he holds the umbrella.
The setting is a downtown urban street with wet pavement reflecting city lights, parked luxury cars, and paparazzi in the background snapping photos.
The photo should look like a real paparazzi shot — slightly off-angle, mid-step motion blur, with realistic lighting and reflections.
Lighting: natural daylight with overcast skies, reflections from wet concrete, realistic shadows, subtle raindrops on the umbrella and clothing.
Camera realism: crisp detail on facial features and clothing textures, shallow depth of field emphasizing the group, with lens flare or light bloom for authenticity.
Mood & tone: grounded, cinematic, and stylish — feels like a moment from a celebrity entourage photo or action-movie press capture, taken with an iPhone by paparazzi.
Style: ultra-realistic, documentary-style street photography with modern cinematic sharpness. {
