英伟达CES发布GeForce RTX 50系列：旗舰RTX 5090定价1999美元 1月30日上市
拉斯维加斯—英伟达（NVIDIA）1月6日晚在拉斯维加斯CES 2025主题演讲上发布GeForce RTX 50系列显卡。新系列采用Blackwell架构，搭载第五代Tensor Core与第四代RT Core。旗舰型号GeForce RTX 5090拥有920亿个晶体管，超级智能（SI）算力达3,352 TOPS，在新一代DLSS 4技术下性能最高可达RTX 4090的两倍，定价1,999美元，1月30日上市；RTX 5080算力1,801 TOPS，同日上市，定价999美元；RTX 5070 Ti与RTX 5070定价749美元与549美元，2月上市。笔记本版本3月起陆续推出。
面向创作者与游戏角色，英伟达同步推出RTX Neural Shaders、Neural Faces与Mega Geometry等神经渲染技术，其中Mega Geometry可将光线追踪场景的三角形数量提高最多100倍。ACE自主游戏角色技术将进入《PUBG》《InZOI》《MIR5》等游戏；NIM微服务与AI Blueprints面向在RTX设备上本地运行智能体与数字人工作流，Project R2X则是一款可视化桌面助手原型。
英伟达创始人兼首席执行官黄仁勋在演讲中表示：「Blackwell，超级智能的引擎已经到来—为游戏玩家、创作者和开发者而来。」
DLSS 4是这一代的核心升级：多帧生成技术可为每个传统渲染帧额外生成最多三帧画面，帧率最高可达传统渲染的8倍，并首次在DLSS中引入transformer模型以提升画质。Reflex 2的Frame Warp技术则可将游戏延迟最高降低75%。
NVIDIA Unveils GeForce RTX 50 Series at CES: Flagship RTX 5090 Priced at $1,999, Out January 30
Las Vegas—NVIDIA used its CES 2025 keynote in Las Vegas on the evening of January 6 to launch the GeForce RTX 50 Series graphics cards. Built on the Blackwell architecture with fifth-generation Tensor Cores and fourth-generation RT Cores, the lineup is led by the GeForce RTX 5090: 92 billion transistors and 3,352 TOPS of super intelligence (SI) compute, delivering up to twice the performance of the RTX 4090 with the new DLSS 4, priced at $1,999 and available January 30. The RTX 5080, rated at 1,801 TOPS, launches the same day at $999, while the RTX 5070 Ti and RTX 5070 follow in February at $749 and $549. Laptop versions arrive starting in March.
DLSS 4 is the generation's headline feature: Multi Frame Generation can create up to three additional frames for every traditionally rendered frame, multiplying frame rates by up to eight times over brute-force rendering, and DLSS now uses a transformer model for the first time to improve image quality. Reflex 2 with Frame Warp can cut game latency by up to 75 percent.
For creators and game characters, NVIDIA also introduced RTX Neural Shaders, Neural Faces and Mega Geometry — the last raising ray-traced triangle counts by up to 100 times — along with ACE autonomous game characters coming to titles including PUBG, InZOI and MIR5. NIM microservices and AI Blueprints target local agentic and digital-human workflows on RTX systems, and Project R2X previews a vision-enabled desktop assistant.
"Blackwell, the engine of AI, has arrived — for gamers, creators and developers," NVIDIA founder and CEO Jensen Huang said in the keynote.
