Xiaomi has unveiled three new chips in its Xuanjie family, expanding its in-house semiconductor portfolio with processors targeting edge artificial intelligence (AI), high-bandwidth AI acceleration and intelligent driving. The company introduced the Xuanjie O3 AI flagship SoC, Xuanjie O100 high-bandwidth AI accelerator and Xuanjie D100 intelligent-driving AI chip. Xiaomi says the devices are intended to provide an AI computing foundation across its ecosystem, spanning consumer devices, vehicles and smart-home applications. The O3 is manufactured using a 3nm process and measures 133mm², incorporating 24 billion transistors. Xiaomi says its Top Channelless technology increases transistor density by 5%, while the number of independently designed standard cells has increased from 480 in the previous-generation O1 to more than 2,400. The processor uses a 10-core CPU comprising six super-large and four large cores, with a maximum clock speed of 4.35GHz. Xiaomi reports Geekbench 6.5 scores of 3,945 for single-core and more than 15,000 for multi-core performance. The O3 also introduces LPDDR6 support, with Xiaomi claiming a memory bandwidth of 113.8GB/s and memory access latency of 82ns. Its cache configuration comprises 12MB of L2, 16MB of L3 and 16MB of system-level cache. AI processing is a particular focus. The O3's NPU provides up to 200 TOPS of tensor computing performance...
