It achieved a highly efficient 82 per cent utilisation rate, the firm added.Advertisement\n\nThe announcement followed a string of breakthroughs by its rivals.\n\nWeeks earlier, world-leading EV maker\n\n[BYD](https://sc.mp/kq173?utm_source=copy-link&utm_campaign=3356760&utm_medium=share_widget)debuted its Xuanji A3, a 4nm smart-driving chip now in mass production. Capable of supporting Level 3 and Level 4 autonomous-driving functions, a trio of Xuanji A3 chips working in tandem can deliver more than 2,100 TOPS of processing power, the company said.Advertisement\n\nHigher TOPS allow a vehicle’s computers to make split-second driving decisions by simultaneously crunching feeds from various sources such as radar and lidar sensors.\n\nAdvertisement\n\nSelect Voice\n\nSelect Speed\n\n1.00x", "url": "https://wpnews.pro/news/smart-driving-chips-the-weapon-of-choice-in-chinas-ev-tech-war", "canonical_source": "https://www.scmp.com/tech/big-tech/article/3357294/smart-driving-chips-weapon-choice-chinas-ev-tech-war?utm_source=rss_feed", "published_at": "2026-06-16 11:00:05+00:00", "updated_at": "2026-06-16 11:24:20.072861+00:00", "lang": "en", "topics": ["autonomous-vehicles", "ai-chips", "ai-products", "ai-infrastructure"], "entities": ["Li Auto", "BYD", "Nvidia", "Horizon Robotics", "Mach M100", "Xuanji A3"], "alternates": {"html": "https://wpnews.pro/news/smart-driving-chips-the-weapon-of-choice-in-chinas-ev-tech-war", "markdown": "https://wpnews.pro/news/smart-driving-chips-the-weapon-of-choice-in-chinas-ev-tech-war.md", "text": "https://wpnews.pro/news/smart-driving-chips-the-weapon-of-choice-in-chinas-ev-tech-war.txt", "jsonld": "https://wpnews.pro/news/smart-driving-chips-the-weapon-of-choice-in-chinas-ev-tech-war.jsonld"}}
