小米玄戒O3芯片全面重构NPU架构：拥有200TOPS张量算力_我的网站

一 |     8月24日消息，小米今日正式发布玄戒O3芯片，定位为面向最高端产品的“AI旗舰SoC”。

二 |     ST. LOUIS -- St. Louis is launching a program that seeks to help low-income families by providing them with $500 monthly payments for 18 months.The program is a signature priority for Mayor Tishaura Jones, who said Tuesday that the money will go to hundreds of city households, the St. Louis Post-Dispatch reported. She believes it will help rebuild neighborhoods and prevent the root causes of crime.“St. Louis’ guaranteed basic income will give hundreds of St. Louis families the resources they need to lift themselves out of poverty, giving them a strong foundation to grow and to thrive,” Jones said at a news conference.The Board of Aldermen approved the program last year. The city will use $5 million in federal pandemic aid. Meanwhile, St. Louis native Jack Dorsey, who co-founded Twitter and Square, is contributing $1 million.Jones announced a website for those interested. Applications will be open between Oct. 23 and Nov. 1, and the city will start sending the money, on debit cards, in December.The concept isn't new. During the pandemic, the federal government temporarily expanded the child tax credit to send families up to $300 per month for each child. Researchers said it cut child poverty in half. Other cities already experimenting with guaranteed basic income include Baltimore; Chicago; Denver; Birmingham, Alabama; and Columbia, South Carolina.In 2021 and 2022, a round of one-time $500 checks went to more than 9,000 St. Louis households, aimed at helping to help pay for groceries, utilities and other essentials.The new effort is expected to send money to roughly 540 St. Louis households with parents or guardians of children attending city public schools, including charter schools. Eligibility is limited to those making 170% of the federal poverty line or less — about $42,000 for a family of three.。该芯片在安兔兔跑分中高达522万分，成为首个突破500万分大关的旗舰级移动平台。    

    玄戒O3的NPU架构经过全面重构，专为Xiaomi MiMo端侧大模型打造，具备200TOPS张量算力与3.13TFLOPS向量算力，端侧AI性能相较上代提升45%。     不止NPU性能强劲，玄戒O3更将全模块融入AI能力。CPU新增双SME2加速单元，GPU集成8颗NX 神经网络加速器。

    ISP内置AINR单元，DPU配备硬件级AI超分辨率模块，ADSP亦内嵌AI引擎。无论是端侧AI推理、硬件级超分插帧，还是夜景视频降噪，均实现全面进化。

四 |     缓存配置同样豪华，主要缓存总计60MB，包含12MB L2缓存、16MB L3缓存，GPU与NPU各自配备独立缓存，另有16MB系统级共享缓存，共同带来行业领先的82ns静态时延表现。
