英偉達修改人工智能芯片以符合中國出口限制

英偉達計劃在未來兩個月內發布一款針對中國市場的降級版H20人工智能(AI)芯片,以符合美國對原版芯片的出口限制。據熟悉該事宜的三名消息人士透露,英偉達已通知包括主要雲計算服務提供商在內的中國客戶,計劃於7月發布修改後的H20芯片。

此舉是英偉達在華盛頓擴大限制中國獲得先進半導體技術的努力面前,試圖維持其在中國這一關鍵市場存在感的最新嘗試。H20曾經是英偉達針對中國市場銷售的最強大AI芯片,但在美國官員上個月通知公司該產品需要出口許可證後,實際上已被擋在市場門外。

英偉達已制定新的技術門檻,這將指導修改後的芯片設計。這些規格將導致與原版H20相比出現顯著降級,包括大幅降低內存容量。另一名消息人士表示,下游客戶可能會修改模塊配置以調整芯片的性能水平。

英偉達拒絕發表評論。美國商務部沒有立即回應評論請求。

中國在英偉達的業務中佔據重要地位,2024年財政年度為公司帶來了170億美元的收入,佔總銷售額的13%。英偉達首席執行官黃仁勳上個月訪問北京,正值美國官員宣布對H20芯片實施新的出口許可證要求之後。在與中國官員會面時,黃仁勳強調了中國作為公司關鍵市場的重要性。

美國自2022年起限制向中國出口英偉達最先進的芯片,理由是擔心這些芯片可能被用於軍事用途。H20是在2023年10月華盛頓加強出口管制後推出的。

包括騰訊、阿里巴巴和抖音母公司字節跳動在內的中國科技巨頭在今年早些時候加大了對H20芯片的訂購力度,因為對像初創公司DeepSeek這樣公司提供的經濟實惠的人工智能模型的的需求不斷增長。據路透社報道,英偉達自1月份以來已累積了價值180億美元的H20訂單。

作為編輯,我認為英偉達此舉反映出美國對中國的半導體出口限制對全球科技產業的影響。英偉達作為全球領先的芯片供應商,其在中國市場的存在感對於公司的業務至關重要。然而,美國的出口限制使得英偉達不得不調整其產品策略,以符合監管要求。

同時,這也凸顯出中國在全球科技產業中的戰略重要性。中國市場對於英偉達等全球科技公司來說,具有巨大的吸引力。如何在遵守監管要求的同時,滿足中國市場的需求,將成為英偉達等公司未來面臨的重要挑戰。

此外,這也引發了人們對全球科技產業未來發展的擔憂。隨著各國政府加強對半導體出口的監管,全球科技產業可能會面臨更大的不確定性。企業需要更加靈活地調整其產品策略和供應鏈,以適應不斷變化的監管環境。

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 striking, high-resolution portrait of a young woman with long, flowing wavy brunette hair, seated gracefully on a simple black wooden chair in a dimly lit studio. She wears an oversized, off-white knitted sweater that drapes loosely over her frame, slipping off one shoulder to reveal smooth skin and add a subtle touch of sensuality. Her pose is elegant and contemplative: one arm rests gently on the chair’s backrest while her hand delicately supports her chin, and her gaze is directed thoughtfully toward the side, creating an intimate and introspective mood. The lighting is expertly crafted with a single soft, directional light source positioned to the side, casting gentle shadows that sculpt her form and highlight the texture of the knitwear and the natural contours of her legs and arms. This chiaroscuro effect enhances the depth and dimensionality of the image, emphasizing the softness of her skin and the intricate weave of the sweater. The background is a smooth, muted dark gray, providing a minimalist and distraction-free backdrop that contrasts beautifully with her light-colored apparel and warm skin tones. *** The composition is a full-body vertical frame that captures the model’s seated posture with perfect balance, positioning her slightly off-center to create visual interest and harmony. The overall color palette is subdued and warm, featuring neutral tones that evoke a sense of calm and understated elegance. The image is impeccably sharp, showcasing fine details such as the delicate waves of her hair, the subtle folds in the fabric, and the natural texture of her skin. The style is classic and timeless, blending modern minimalism with emotive portraiture to convey quiet strength, beauty, and introspection.
