微軟發表 Surface Laptop Ultra 搭載 NVIDIA RTX Spark

微軟與 NVIDIA 合作推出搭載 Grace Arm CPU 與 Blackwell GPU 的 AI 筆電,強調本機執行大型模型能力

Quick Look

微軟於舊金山發表 Surface Laptop Ultra,搭載 NVIDIA RTX Spark 平台,具備 20 核心 Grace CPU 與 Blackwell GPU。該筆電主打本機執行大型 AI 模型,售價 2,599 美元起,預計 10 月 16 日出貨。

AI-generated summary

Why It Matters

微軟與NVIDIA合作開發RTX Spark平台,旨在將雲端等級的AI運算能力帶入筆記型電腦。

微軟10月7日在舊金山發表新款旗艦 AI 筆電 Surface Laptop Ultra,搭載 NVIDIA RTX Spark 平台,最高配備 20 核心 Grace Arm CPU、6,144 核心 Blackwell RTX GPU,以及 128GB 統一記憶體,FP4 AI 運算效能達 1 petaflop。這款筆電以本機執行大型 AI 模型為主要訴求,美國入門售價 2,599 美元,預定10月16日出貨。台灣電商平台也開始展開預購。

Surface Laptop Ultra 採用 NVIDIA Grace CPU 與 Blackwell GPU 組合,兩者共用最高 128GB 記憶體。這項設計讓 CPU 與 GPU 能使用同一套記憶體資源,減少大型模型運算時的資料搬移需求,也讓數十 GB 的模型權重有機會直接載入筆電執行。

微軟同步導入 MAI Code 1.1 Flash 混合專家模型(MoE),總參數達 1,370 億,每次推論約啟用 68 億參數。模型經約 3 位元量化後,權重容量縮減至約 53GB,支援最高 256K 上下文。在 Surface Laptop Ultra 的測試中,短提示生成速度約每秒 60 個 token;當上下文增加至 256K,速度則降至每秒 40 個 token 以下。

NVIDIA 也預告推出參數超過 700 億、壓縮後容量約 20GB 出頭的 Nemotron 模型,並在現場展示 2,840 億參數的 DeepSeek V4 Flash。GitHub 也推出 HydraFusion 實驗預覽,將能擴充 Copilot 的模型支援。

這次發表會由微軟執行長納德拉(Satya Nadella)與 NVIDIA 執行長黃仁勳同台,兩家公司提出「混合式智慧」(Hybrid Intelligence)策略,依工作負載分配本機與雲端運算。微軟也同步在 Windows 11 推出 Microsoft Execution Containers(MXC),由系統限制 AI 代理可存取的資料夾、網路位置及憑證,提供行程、工作階段、WSL 容器及微型虛擬機等隔離選項。MXC 宣布即日起全面提供,首波支援 GitHub Copilot、OpenAI Codex、LM Studio 等工具,Claude Code、Perplexity 及 Raycast 則排定後續整合。

Surface Laptop Ultra 使用 Arm 架構,也讓軟體相容性成為選購時需要注意的問題。除了大型模型的推論速度,部分專業應用程式、硬體驅動及遊戲反作弊系統能否在 Windows on Arm 環境正常運作,會直接影響使用者是否能將這款筆電作為主要工作設備。

Surface Laptop Ultra 已於10月7日開放美國市場預購,入門款售價 2,599 美元,頂規版本為 5,899 美元,預定10月16日出貨。日本入門售價約 51萬3,480 日圓,台灣價格尚未公布。華碩、戴爾、惠普、聯想與微星也同步推出採用 RTX Spark 平台的合作機種。

微軟另外準備了開發者導向的 Surface RTX Spark Dev Box,售價 5,999 美元,預計11月透過美國官網出貨。相較於 Surface Laptop Ultra 的行動使用定位,Dev Box 主要面向需要固定本機 AI 開發與模型測試環境的使用者。

ChatGPT answer interface has been overhauled! Add interactive buttons, free users can also use it

OpenAI imports the GPT-6 model into ChatGPT and launches a new smart interface that supports interactive elements such as images, charts, forms, and clickable buttons. Users can adjust the reply content through interaction. Paid users use the GPT-6 Sol model, and free and Go plans use the GPT-6 Luna model. It will be launched one after another on the 7th and will be expanded to all users on October 8th. Both computers and mobile phones are supported.
