美國管制升級!輝達AI晶片輸中受阻,隱瞞客戶?




美國新出口規定突襲英偉達,中國客戶未獲提前通知

新加坡 — 據兩名知情人士透露,美國晶片巨頭英偉達(Nvidia)在約一星期前接獲美國政府通知,要求其銷售針對中國市場的人工智能晶片H20必須申請出口許可證,但英偉達並未提前警告部分重要中國客戶。

英偉達週二公布,美國官員於4月9日告知公司,銷往中國的H20晶片將需取得出口許可證。此舉是美國限制中國取得先進半導體技術的最新措施,旨在維持其在人工智能技術上的領先優勢。

不過,根據兩名消息人士透露,主要中國雲端企業仍預期今年底前收到H20晶片,對新規定毫不知情,甚至英偉達中國銷售團隊在官方公告前似乎亦未被告知。由於事件敏感,消息人士要求匿名。

英偉達拒絕對此發表評論。

出口管制將嚴重影響英偉達在中國這一重要市場的業務。據兩名消息人士及另一名知情者透露,英偉達自今年初以來已獲得價值180億美元的H20晶片訂單。

截至去年1月26日結束的財政年度,中國市場為英偉達帶來170億美元收入,佔公司總銷售額約13%。

受此消息影響,英偉達股價週二盤後交易下跌6%。公司表示,由於需遵守出口許可規定,第一季(截至4月27日)將計提最多55億美元的相關費用,美國政府週一告知該限制將無限期生效。

英偉達說,此次費用主要關於庫存、採購承諾及相關H20產品準備金。

據路透社2月報導,包括騰訊、阿里巴巴及字節跳動(TikTok母公司)等中國科技巨頭,因應創業公司DeepSeek等對經濟型AI模型需求激增,已增加H20晶片訂單。阿里巴巴、字節跳動及騰訊尚未回應置評請求。

H20是英偉達在最新一輪美國出口限制生效後(2023年10月)推出的主要合法銷售中國市場的晶片。自2022年起,美國已禁止向中國出口英偉達最先進的晶片,擔憂相關技術被用於軍事發展。

分析師指出,H20出口限制可能利好中國AI晶片製造商,尤其是華為,其產品與英偉達晶片相競爭。

新加坡White Oak Capital Partners投資總監邱諾里表示:「美國限制H20系統,實際上是在推動英偉達中國客戶轉向華為的AI晶片。」

他補充:「隨著華為獲得更多客戶及開發經驗,其晶片設計與軟件能力預料將迅速提升。」

評論分析:美國出口管制下的中美晶片競爭新態勢

這次美國對英偉達H20晶片銷華實施出口許可限制,反映出美國在高科技領域對中國持續施壓的策略進一步加碼。英偉達作為全球AI晶片龍頭,向中國市場銷售的限制不僅影響自身巨大收入,也可能重塑中國AI芯片生態。

值得注意的是,英偉達未提前通知主要中國客戶,可能導致客戶端供應鏈出現混亂與信任危機。這種「突襲式」的政策執行,凸顯了國際科技供應鏈的脆弱性與地緣政治風險。

對中國而言,限制雖然短期內打擊了外國高端晶片供應,但同時也可能加速國內芯片企業如華為的崛起。華為和其他本土AI晶片製造商將有機會填補市場空白,加速技術自主發展,這與美國意圖遏制中國技術進步的初衷形成矛盾。

從長遠來看,美國的限制政策或將激發中國加快半導體自給自足步伐,倒逼本土創新,反而可能在中美科技競爭中催生更多變數。對於投資者和產業觀察者而言,未來中美在AI晶片領域的角力將更加白熱化,雙方如何平衡技術進步與地緣政治壓力,將是全球科技產業的一大焦點。

Ultra-realistic cinematic photograph, 9:16 vertical.
Use my uploaded female subject as the ONLY face reference — her face, bone structure, proportions, and identity must remain 100% accurate. She is sitting low and relaxed on a worn vintage couch inside a messy 90s-era bedroom, dripping with grunge attitude and self-confidence. The entire room tells a story of obsession — the walls are completely covered in posters, photos, magazine clippings, and polaroids of HER, all different versions of her: glam looks, grungy looks, party looks, soft looks, edgy looks, all chaotic and layered, taped and pinned unevenly like a shrine to herself. Wardrobe: She wears an oversized, slouchy dark hoodie left open, revealing a white tube top underneath. The outfit is provocative but raw — lots of exposed skin at the waist, collarbones, shoulders, and legs. The vibe is unapologetically sexy, rebellious, and confident. Bare legs or very short bottoms, worn sneakers or socks, very lived-in 90s styling.
Hair & makeup: Hair is messy, slightly undone, effortlessly sexy. Makeup is grungy-glam — smoky eyes, dark liner, slightly smudged, natural but seductive skin texture. No over-polish.
Pose & expression:
She sits back into the couch with dominant, careless confidence — legs apart or casually stretched, shoulders relaxed. Her expression is sultry, knowing, and powerful, like she’s fully aware the entire room revolves around her. She looks down toward the camera, owning the frame.
Camera & composition:
The camera is placed very low on the floor, angled sharply upward toward her, creating dramatic depth perception. Her legs and body feel larger in the foreground, her face looming above, while the poster-covered walls stretch upward behind her, creating a warped, immersive perspective. Slight wide-angle distortion for intensity. Lighting: Moody, low-light bedroom lighting — a mix of cool blue tones and dirty warm highlights. Neon or lamp glow spills across the posters. Shadows fall unevenly across the room, adding grit and texture. Film grain, subtle motion blur energy, raw 90s music-video atmosphere. Overall vibe: Sexy, grungy, chaotic, self-obsessed Edit this photo without changing her face 100% to reveal a young woman with an oval face and ideal body, not skinny.

Her shiny, ash brown with pink highlight, waist-length hair, loose curls styled with curtains bangs giving a Korean-style aesthetic.
Her head is tilted slightly to the side (head tilt), creating a chic and elegant look.

This photo exudes a feminine and sensual yet calm aura. The skin tone and outfit make the subject stand out.
The background is slightly blurred (out of focus), as if she were in her white interior car taking a selfie.
