**Nvidia未來的Blackwell Ultra GPU系列將改名為B300系列**

據TrendForce報道,Nvidia將其Blackwell Ultra產品線重新命名為B300系列,以更好地與即將推出的B100和B200產品區分開來。這個全新的系列將會有更高的性能和升級的記憶體配置,但價格也會相應提高。

原本預計命名為Nvidia B200 Ultra的產品將重新命名為B300,而GB200 Ultra則改為GB300。此外,B200A Ultra將更名為B300A,GB200A Ultra則改為GB300A。

值得注意的是,這些信息尚未得到官方確認。Nvidia之前的產品路線圖中曾提及”Blackwell Ultra”作為一個產品系列,但未具體說明產品名稱。無論Blackwell Ultra是否會被命名為Blackwell B200 Ultra或其他名稱,官方都未曾宣布。

Nvidia的B100、B200和GB200系列配備192GB的HBM3E記憶體,使用8層HBM3E記憶體堆疊。相比之下,B300和GB300將配備288GB的HBM3E,使用八個12層堆疊。由於B300系列產品將擁有更多的記憶體(可能還有更高頻率的GPU和/或更多處理核心),因此價格將高於B100和B200解決方案。相對而言,更具成本效益的B300A和GB300A將配備144 GB的記憶體,使用四個12層HBM3E堆疊。這意味著Nvidia的大多數GPU將轉向12層HBM3E,這將需要DRAM製造商調整其HBM3E供應鏈。

Nvidia的B100/B200和GB200系列預計將於2024年第四季度至2025年第一季度開始出貨。由於一些硬件問題,出貨時間有所延遲,但Nvidia已經解決了這些問題。TrendForce認為,Nvidia將在2025年第二或第三季度推出B300系列。專為伺服器OEM設計的B300A將於2025年中期進入量產。值得注意的是,TrendForce聲稱Nvidia原本計劃為OEM推出B200A,但由於對低階GPU的需求低於預期,決定直接推出B300A。

雖然OEM業務對Nvidia很重要,但公司表示將優先考慮其自有的NVL機架解決方案,這些機架配備36個或72個Blackwell GPU,專為包括亞馬遜網絡服務、Meta和微軟在內的雲服務供應商設計。Nvidia的NVL36和NVL72機器將配備更昂貴的GPU,並且相較於傳統GPU伺服器成本更高,部分原因是新的Blackwell GPU消耗大量電力,需要液冷。轉向這些機器將伴隨更高的相關成本,因為公司將需要升級到更先進的數據中心基礎設施。

**評論:**

Nvidia這次的產品線重新命名和性能升級,顯示出公司在高性能計算領域的野心。隨著AI和雲計算需求的增長,Nvidia選擇擴大其高端GPU的能力,這對市場來說無疑是一個強烈的信號。特別是在全球供應鏈緊張的背景下,Nvidia能否順利推動這些新技術的應用,將是一個值得關注的話題。此外,對於伺服器OEM和雲服務提供商來說,這些新產品的高成本和高能耗意味著需要重新評估其基礎設施投資策略。這是否會推動更廣泛的技術創新和市場競爭,將是未來觀察的重點。

Create a hyper-realistic 8K close-up body portrait of a female model, using the uploaded photo as the exact facial reference. Maintain 100% accuracy of the facial features — do not alter or modify any aspect of the face. Render the skin texture, lighting, and overall composition with photo-realistic detail, ensuring lifelike color tones and natural depth of field. A man with his original hair is sitting casually on a white cube, smiling warmly at the camera. He is wearing a cream-colored cable-knit sweater, blue jeans, and brown loafers. His legs are crossed, with one hand resting on his knee.
The background reveals a cozy and festive living room. A large, beautifully decorated Christmas tree with numerous warm lights and gold ornaments stands prominently behind him. Several wrapped gift boxes are visible at the base of the tree. To his left, another smaller decorated Christmas tree and a wreath on the wall further enhance the holiday atmosphere. The lighting is soft and inviting, creating a warm and welcoming scene. 一隻在香港茶餐廳喝奶茶的貓 Base Setup
