Nubia NaviX Ultra will launch in September with CXMT 10,667-megabits-per-second low-power double-data-rate 5X memory, its first mass-production application.

Nubia’s NaviX Ultra is scheduled to be unveiled in September with ChangXin Memory Technologies, or CXMT (长鑫存储), low-power double-data-rate 5X memory rated at 10,667 megabits per second. CXMT described this as its highest-speed LPDDR5X product.

The device will represent the first mass-production application of a domestically produced 10,667-megabits-per-second LPDDR5X chip, according to the report. This refers specifically to the memory component entering mass production in a commercial handset.

The report described NaviX Ultra as a new-generation Doubao AI phone jointly developed by ByteDance and ZTE. It also characterized the device as an AI-agent phone, but did not provide detailed specifications for the agent functionality.

No memory capacity, processor model, device price, exact launch date, shipment target, or sales availability was disclosed. The report also did not provide latency, power-consumption, or comparative memory-bandwidth benchmarks.
