Xiaomi announced the XRING O3 on August 24, 2026, succeeding its XRING O1 smartphone SoC. The chip scored 5.22 million on AnTuTu, the first flagship SoC past 5 million. It uses a 10-core all-big-core CPU design, with Geekbench multi-core above 15,000 and a 60 percent performance gain over the prior generation.
The XRING O3 is built around a 10-core all-big-core CPU, meaning it drops the low-power small cores used in conventional smartphone chips in favor of high-performance cores throughout. Xiaomi says the design pushes Geekbench multi-core past 15,000 points for the first time.
For graphics, the chip debuts the G2-Ultra NX GPU, reported at 85 percent better performance and 64 percent lower power draw, with a 16-core configuration and third-generation ray tracing support. Xiaomi also calls XRING O3 the world's first mobile processor to support LPDDR6 memory, reaching 113.8GB/s of bandwidth.
The NPU was completely redesigned around on-device large models running Xiaomi MiMo, delivering 200TOPS of tensor computing and 3.13TFLOPS of vector computing. Xiaomi said the chip was crafted over a 459-day development period.
