Nvidia搶攻中國市場 推降階版Blackwell晶片




Nvidia急推精簡版Blackwell GPU 應對中國市場出口限制

Nvidia公司並未放棄中國市場,反而正加快腳步,開發一款全新、低功耗、較便宜的人工智能晶片,預計將會比現時受美國出口限制的H20型號更平價。

這款新顯示卡將歸類為Nvidia最新一代Blackwell處理器系列,但效能會大幅低於面向西方市場的型號。根據路透社今日率先披露的消息,新晶片售價約為6,500至8,000美元,遠低於H20舊架構晶片的12,000美元定價。

美國再收緊出口 Nvidia被迫轉型

今年四月,美國政府進一步收緊出口禁令,禁止Nvidia向中國出口H20 GPU。該晶片採用Hopper架構,與美國本土銷售的H100及H200產品相似,但頻寬及連接速度較低,原本已為配合早前出口限制而設計。不過,特朗普政府官員認為,即使是這款降規版H20,對於美國在AI產業的最大競爭對手中國來說,依然過於強大。

這項決定出台不久前,中國初創公司DeepSeek Ltd.剛剛利用H20晶片集群,研發出推理能力可媲美OpenAI等美國頂尖企業的基礎大模型,令外界側目。

新晶片規格與生產方式

據路透社引述三位知情人士透露,Nvidia新晶片的低價反映其規格較低、生產工序更為簡單。這款產品將以Nvidia RTX Pro 6000D為基礎,屬於伺服器級Blackwell GPU,但只會配備傳統GDDR7記憶體,而非其他Blackwell晶片採用的高頻寬記憶體。消息指,最快六月便可投產。

同時,新晶片不會用上台積電最先進的“Chip-on-Wafer-on-Substrate”封裝技術,而是採用較舊的製程。

Nvidia發言人拒絕評論新產品,但表示公司仍在評估針對中國市場的「有限選項」。「在我們落實新產品設計並獲得美國政府批准前,基本上已經被排除在中國五百億美元數據中心市場之外。」發言人說。

中國市場仍是關鍵 Nvidia持續應變

儘管受到制裁,中國依然是Nvidia重要市場,去年佔其全年收入13%。美國過去兩度禁止Nvidia向中國出口最先進AI晶片,每次Nvidia都會針對市場需求推出降規版產品。

Nvidia在中國GPU市場最大競爭對手是華為(Huawei),其自家Ascend 910B晶片正逐步追趕。White Oak Capital Partners半導體分析師Nori Chiou向路透表示,預計華為最快一至兩年內就能達到Nvidia降規版晶片的效能。不過,Nvidia仍有一項明顯優勢,就是其GPU能與CUDA平台整合,而CUDA已成為AI開發者的主流選擇。

CUDA是專為Nvidia顯示卡優化應用程式和AI模型的程式架構,因為開發社群龐大,許多開發者都傾向繼續使用。

四月出口禁令令Nvidia一次過註銷超過55億美元存貨,行政總裁黃仁勳亦坦言,這次更失去了超過150億美元的銷售機會。

黃仁勳表示,公司最初曾考慮進一步壓縮H20晶片規格,但發現舊有Hopper架構已無法再作大幅度修改。

新一輪出口限制,重點是限制GPU記憶體頻寬——即處理器與內存系統之間數據傳輸速度。對於AI運算來說,頻寬愈高,處理大量數據的能力愈強。

編輯評論:Nvidia的中國策略與全球AI競爭新格局

從這次Nvidia被迫推出精簡版Blackwell GPU的舉動,可以看到美中科技戰已經進入「以軟制硬」的深水區。美國政府一再收緊AI晶片出口,Nvidia則屢屢以降規、降價方式「繞道」繼續服務中國市場,雙方可謂各出奇謀。這場科技拉鋸戰,已不是單純的技術競賽,更涉及全球供應鏈、產業自主權、甚至國家安全。

值得留意的是,雖然Nvidia短期內仍靠CUDA平台的生態圈穩佔優勢,但中國本土如華為等企業正急起直追。隨著國產AI軟硬件生態逐步成熟,未來中國市場對Nvidia的依賴可能會逐步減少。長遠而言,這種「技術封鎖—降規應對—本土替代」的循環,或會令全球AI產業格局出現根本性變化。

再者,Nvidia這次開發新晶片時,選擇不用最先進製程,而是採用較舊技術,反映出在地緣政治壓力下,全球半導體產業的創新路徑亦被迫調整。這對於香港、甚至亞洲區的科技企業來說,是一面鏡子——如何在全球供應鏈重組、技術標準分化的情況下,靈活部署自身策略,將會是未來幾年最關鍵的生存課題。

這場圍繞AI晶片的「貓捉老鼠」遊戲,最終誰勝誰負,還要看技術創新、政策走向與市場應變三者如何互動。Nvidia與中國市場的博弈,絕對值得香港讀者繼續關注。

A captivating portrait of a young Asian woman, inspired by Imada Mio and embodying an exquisitely delicate, doll-like (精緻洋娃娃臉) aesthetic. She has large, round, expressive eyes that radiate innocence and curiosity, subtly accented with a moist shimmer. Her petite V-line face is framed by soft, rosy cheeks, and her lips are naturally pink and slightly parted, exuding an energetic, slightly flirty, yet pure aura. Her expression is a candid blend of sweetness and playful allure.

Her long, dark brown hair is artfully tousled with a messy morning (剛睡醒的凌亂感) effect—loose strands fall gently around her face, conveying natural volume and effortless beauty. The hair has a silky texture, catching the light in places, suggesting a recent awakening.

She is dressed in an oversized, translucent white button-down shirt (男友風白襯衫) with the top buttons casually undone, delicately revealing her collarbones and a slender neckline. The shirt drapes loosely, giving a tasteful "bottomless" look (下衣失蹤風格), her bare legs just barely visible beneath the shirt's hem, enhancing the innocent-meets-sensual ambiance.

The composition is styled in the manner of a Japanese Gravure Photobook (寫真集風格), exuding a pure & sexy vibe with an airy, dreamy atmosphere. Employ bright, high-key lighting for a clean, luminous effect that highlights her velvety soft skin texture. Use Fujifilm PRO 400H film tones for subtle pastel hues, gentle contrast, and a seamless blend of natural colors, further enriching the soft, ethereal, and intimate photographic quality.

The background is minimalist and softly blurred, ensuring complete focus on the subject, and enhancing the overall sense of warmth, comfort, and inviting allure typical of high-end Japanese photobooks.
