❯ Xiaomi 18 Fold arrives in September, debuting CXMT LPDDR6 and the in-house 3nm Xring O3

a double debutXiaomi and CXMT confirmed that the Xiaomi 18 Fold, launching in September, will simultaneously debut CXMT’s LPDDR6 memory and Xiaomi’s in-house 3nm Xring O3 processor. It is the first time a domestically produced LPDDR6 part ships alongside a flagship-class processor. Reuters reports a shipment target of 200,000 to 300,000 units.

chip specsPer TrendForce, Xiaomi’s in-house silicon previously topped out at the Xring O1; the Xring O3 is fabbed on TSMC’s 3nm process and is the first mobile processor to support LPDDR6, hitting 10,667Mbps and 113.8GB/s of memory bandwidth, a 48% gain over the O1. It packs 24 billion transistors, 26% more than its predecessor, on a 133mm² die. Xiaomi has two more chips at TSMC: the 6nm XRING O100 NPU for running its MiMo model on device, and the 3nm XRING D100 for autonomous driving.

a validation runTwo to three hundred thousand units is a validation run, not a volume play. The pressure lands on Qualcomm’s and MediaTek’s share assumptions in China’s flagship tier: both are preparing 2nm parts while Xiaomi already has a 3nm in-house chip in a shipping phone. For CXMT, this pushes the proving ground for domestic memory from the server side into consumer devices. Watch the return and yield data on those 200,000 units.

▪ SIGNALAn in-house SoC paired with domestic memory in one phone — what Xiaomi is really selling is proof that a supply chain works.
