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。 Breakthrough new research could significantly increase supply of organs for people with rarer blood types waiting for a transplant, reported The Guardian.,A team of scientists from the University of Cambridge have successfully altered the blood type of three donor kidneys. By flushing blood infused with a special enzyme through a human kidney the scientists removed the blood type markers lining the blood vessels of the organ.,The procedure required using a device that is connected with a donor’s kidney to pass oxygenated blood through it - a normothermic perfusion machine. As a result, the organ was converted to type O, considered the universal donor.,Blood Group Compatible,As the blood type of a donor must be compatible with the recipient’s, the new development could increase the supply of kidneys available for transplant.,A kidney from someone with blood type A cannot be transplanted to someone with blood type B, or visa versa. In such a case, the receiving body’s immune system would reject the new organ, interpreting the different blood type as foreign.,So changing the blood type to the universal O would mean the donor organ could be used for people with any blood type.,“Our confidence was really boosted after we applied the enzyme to a piece of human kidney tissue and saw very quickly that the antigens were removed. After this, we knew that the process is feasible, and we just had to scale up the project to apply the enzyme to full-size human kidneys,” Serena MacMillan, a PhD student at the University of Cambridge, said.,Scientists involved in the research, funded by charity Kidney Research UK and due to be published in the British Journal of Surgery, clarified that the outcome might have particular implications for minority ethnic groups.,Science & TechGood News for ABs: Scientists Can Now Change People's Blood Type21 February, 16:34 GMT,Some blood groups such as O Rh positive and B Rh positive are more prevalent among black, Asian and minority ethnic communities. To complicate matters further, some rare blood types are only found within the black, Asian and minority ethnic communities,This typically places them at a disadvantage, as they struggle to find a match. With low donation rates from these populations, stressed the researchers, sometimes such patients wait for as long as over a year for a compatible donor. They cited figures from 2020-21 showing that just over 9% of total organ donations in the UK came from black and minority ethnic donors. On the other hand, black and minority ethnic patients make up 33% of the kidney transplant waiting list.,“It’s very exciting to think about how this could potentially impact so many lives,” added Serena MacMillan.,The “potentially gamechanging” research was applauded by Dr Aisling McMahon, the executive director of research at Kidney Research UK.,The scientists will now test the reintroduction of other blood types and observe how the novel approach in clinical settings.。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。

B | 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%。

C | 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。
