With GeForce Super GPUs missing in action, Nvidia focuses on software upgrades
摘要
英伟达在CES上未发布新款GeForce显卡，转而聚焦软件升级。CEO黄仁勋的主题演讲集中讨论AI业务，游戏相关更新通过后续视频发布。主要软件更新为DLSS 4.5，通过第二代Transformer模型和扩展数据集训练，提升了超分辨率与帧生成技术，尤其在性能与超性能模式下改善了低分辨率源图像的画质预测。
For the first time in years, Nvidia declined to introduce new GeForce graphics card models at CES. CEO Jensen Huang's characteristically sprawling and under-rehearsed 90-minute keynote focused almost entirely on the company's dominant AI business, relegating the company's gaming-related announcements to a separate video posted later in the evening.
Instead, the company focused on software improvements for its existing hardware. The biggest announcement in this vein is DLSS 4.5, which adds a handful of new features to Nvidia's basket of upscaling and frame generation technologies.
DLSS upscaling is being improved by a new "second-generation transformer model" that Nvidia says has been "trained on an expanded data set" to improve its predictions when generating new pixels. According to Nvidia's Bryan Catanzaro, this is particularly beneficial for image quality in the Performance and Ultra Performance modes, where the upscaler has to do more guessing because it's working from a lower-resolution source image.
