Once reliant on Samsung and SK Hynix, Chinese smartphone makers are turning to CXMT
China's ChangXin Memory Technologies (CXMT) is supplying LPDDR5X DRAM chips for ZTE-backed Nubia's NaviX Ultra smartphone. This marks CXMT's first large-scale use of domestically made LPDDR5X chips in a flagship handset. The Nubia NaviX Ultra, priced from 5,999 yuan (US$885), is also the first mass-market smartphone to feature ByteDance's Doubao AI assistant. This development reflects CXMT's growing presence among Chinese smartphone vendors amid a global memory shortage.
CXMT's LPDDR5X chips in Nubia's NaviX Ultra represent a concrete step toward China's self-sufficiency in high-end memory. The chips boast a data transfer speed of up to 10,667 megabits per second, matching global standards. The development is less about immediate market share and more about validating domestic production capabilities for advanced components, especially as Chinese vendors push into premium segments. It shows a direct response to past reliance on foreign suppliers like Samsung and SK Hynix.
For the broader Asia tech landscape, this signals a deepening of China's internal supply chain for critical components. It reduces the leverage of South Korean memory giants in the Chinese market. Companies like Xiaomi, already using CXMT chips in some models, will likely expand their domestic sourcing. The test for CXMT is whether it can scale production and maintain quality consistently to meet the demands of top-tier devices beyond initial flagship integrations.
The integration of ByteDance's Doubao AI assistant into the Nubia handset is also notable. This reflects a trend of Chinese tech giants bundling their AI capabilities directly into hardware. The thing to watch is how quickly this AI-hardware integration expands across other Chinese smartphone brands. It will drive competition among domestic AI model developers and handset makers.
