足不出户 走遍全世界
一 | 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。 “The incident took place within Ethiopian territory after incursions by a Sudanese regular army unit supported by elements of the terrorist TPLF,” the Ethiopian Foreign Ministry said in a Monday press release, referring to the Tigray People’s Liberation Front (TPLF) armed group that controls the northern Tigray province.,“The Ethiopian Government regrets the loss of life as a result of a skirmish between the Sudanese army and a local militia of which an investigation would be carried out soon,” the ministry said, adding that it “categorically rejects the misrepresentation of these facts by the Sudanese defense forces that unjustly put the blame on Ethiopia while it was the Sudanese army unit that has crossed into the Ethiopian border provoking the incident.”,“The Government of Ethiopia believes that the incident was deliberately concocted to undermine the deep-rooted relations between the peoples of Ethiopia and the Sudan. On top of that, the incident was designed to destruct Ethiopia from its path of peace and development,” the ministry added.,Sudan Recalling Ambassador to Ethiopia After Deaths of Seven Soldiers18:02 GMT,A day prior, Sudan’s ruling armed forces, which seized power from the civilian leadership of the provisional government last October, accused the Ethiopian Army of an “execution of seven Sudanese soldiers and a citizen who were prisoners of war.”,“[T]his treacherous situation will not pass without a response,” the Sudanese Army said, vowing it would “respond to this cowardly behavior.”,On Monday, Sudan’s acting foreign minister, Ali Al-Sadiq Ali, summoned the Ethiopian ambassador demanding answers and recalled Sudan’s ambassador in Addis Ababa.,The clash reportedly occurred in the vicinity of Al-Fashaga, an area of rich farmland in Sudan that abuts the border with Ethiopia and Eritrea. Addis and Khartoum have long feuded over control of the area, but reached a compromise in 2008 that allowed Ethiopian farmers to work the land under Sudanese administration. However, after the TPLF rebelled against the Ethiopian government in November 2020, Sudanese forces re-occupied the area, reigniting the dispute.,Sudan-Ethiopia border Al-FashaqaSudan-Ethiopia border Al-Fashaqa,It also comes amid an ongoing refugee problem in Sudan, where the UN Refugee Agency has recorded more than 73,000 Ethiopians who have fled the fighting in Tigray, and a heated dispute between Ethiopia and downstream nations like Sudan and Egypt over the filling of the Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile.。
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。
