A | 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。 In a brutal act of slaughter in broad daylight, a Hindu shopkeeper was allegedly beheaded by two Muslims in the historical city of Udaipur in Rajasthan.,The deceased had reportedly shared a social media post supporting Nupur Sharma, the suspended spokeswoman of India's ruling Bharatiya Janata Party (BJP) who made disparaging remarks about the Prophet Mohammed during a live TV debate on 26 May.,The killers posted a video of the decapitation and threatened to take the lives of Prime Minister Narendra Modi and Nupur Sharma as well.,State administrators have deployed hundreds of security personnel as protests erupt across the western Indian city. Shops in several parts of the city have been closed since the incident.,State chief Ashok Gehlot promised that those who had been involved in the murder would be strictly punished and appealed to citizens to maintain peace and not share any related videos.,"This is a very worrying incident. It is unfortunate and shameful. There are palpable tensions across the country. The atmosphere needs to be fixed. I appeal to Prime Minister Modi and the Home Minister [Amit Shah] to address the nation and calm the atmosphere," Gehlot said.,The state chief, who is from the opposition Congress party, has said that the atmosphere is so tense that whoever, Hindu or Muslim, is in the minority in number in any small town or village feels "insecure and threatened by the majority".,Udaipur Police have launched an inquiry to find the accused.,Sharma's comments prompted protests and complaints from several Muslim countries, including Qatar and Kuwait. Hundreds of people have been arrested across India during public unrest。 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。
