小米玄戒O3首秀：硬件原生AI超分+插帧！3.2K也能跑满120帧_我的网站

一 |     (ECNS) -- China recorded improvements in both air and water quality in the first seven months of 2026, with average PM2.5 concentrations falling 6.2% year on year, Minister of Ecology and Environment Huang Runqiu said Thursday.    The average concentration of fine particulate matter, or PM2.5, fell by 1.8 micrograms per cubic meter from a year earlier, while the proportion of days with good air quality increased by 3.9 percentage points, Huang said at a press conference held by the State Council Information Office.         The proportion of surface-water monitoring sections meeting Grade I-III water quality standards reached 86.5%, up 2.4 percentage points year on year. Water quality in the main streams of the Yangtze and Yellow rivers remained at Grade II.    (By Helen Mo, intern Yang Hongran)                    。    8月24日消息，小米玄戒O3芯片今天正式发布，GPU内部集成了8核NX神经网络加速器，在硬件层面原生实现AI超分和插帧，3.2K分辨率下也能稳定跑满120帧。          具体来看，玄戒O3首发发16核G2-Ultra NX图形处理器，支持第三代光线追踪，整体算力达到36TOPS。         性能方面相比上一代玄戒O1提升85%，Aztec Ruins 1440P跑分213分，是A19 Pro的2.2倍；Steel Nomad Light 4657分，领先A19 Pro约55%；Solar Bay Extreme 3628分，比玄戒O1暴涨182%，能效同时大幅改善，同性能下功耗降低64%。              在AI渲染方面，传统手机的AI图形增强方案渲染数据必须离开GPU，经过SLC或DDR内存搬运到NPU，NPU处理完再搬回GPU继续渲染。一来一回两次数据搬运，延迟和功耗都浪费在数据传输上。         玄戒O3的做法是把NX神经网络加速器塞进GPU渲染管线内部，数据从几何处理、光栅化、着色到NX推理、后处理，全流程在GPU子系统内闭环完成，不需要任何数据搬运。         硬件原生AI超分下，540P分辨率经2倍超分后画质媲美原生1080P，单帧游戏功耗降低20%，在3.2K分辨率下，两款开放世界游戏30分钟实测平均帧率分别达到119.7fps和119.1fps，基本贴满120帧上限。这意味着玄戒O3不需要靠降低分辨率来换取帧率，高画质和高帧率可以同时兼顾。
