CXMT will supply nubia's NaviX Ultra with LPDDR5X memory running at up to 10667 megabits per second, which both companies describe as the first mass-production use of a domestically made chip at that speed. China approved three solid-state battery standards for drafting, covering performance, safety and service life for electric vehicle cells, with public comment drafts expected by the end of 2026. Horizon Robotics said yesterday that cumulative production of its Journey driver assistance chips passed 15 million units, and a Xinhua blue book put it ahead of Nvidia in China's intelligent driving chip market.
CXMT will supply the nubia NaviX Ultra with LPDDR5X memory, the low-power standard used in handsets, running at up to 10667 megabits per second. That is its second flagship design win in two weeks, after the Xiaomi 18 Fold LPDDR6 part (covered August 25th). Both companies call it the first mass-production use of a domestically made chip at that speed. CXMT says the grade runs about 25% faster than the mainstream version, and with it shipping the company now covers every speed from mainstream to flagship. CXMT, or ChangXin Memory Technologies, is China's largest maker of DRAM, the working memory a processor reads and writes as it runs, and its slower LPDDR5X grades entered mass production in May 2025. The NaviX Ultra is the ByteDance and ZTE phone built around ByteDance's Doubao assistant, and it goes on sale this month.
