The XRing O1 launched last month as Xiaomi's first in-house chipset since the Surge S1 in 2017. It performs excellently, too, with a series of hands-on benchmark tests confirming parity with flagship rivals like the Snapdragon 8 Elite and MediaTek Dimensity 9400.

Xiaomi launched its first flagship in-house chipset, XRing O1, last month. The chipset made its debut aboard the Xiaomi 15S Pro and Xiaomi Pad 7 Ultra in China, with the former now being put through a series of hands-on benchmark tests by Fat Wei on Weibo.

On the CPU side, the Xiaomi 15S Pro and XRing O1, scores a max of 3,039 and 9,458 on Geekbench 6's single-core and multi-core tests respectively.  On AnTuTu, the pair delivers a CPU score of 632,832. All of those numbers confirm that Xiaomi's XRing O1 matches the Dimensity 9400 and Snapdragon 8 Elite in the CPU department—and flat-out surpasses both chipset's average performance. 

XRing O1 is a tad weaker on the GPU end, unfortunately. The Xiaomi 15S Pro's Immortalis-G925 MC12 GPU earns it a score of 2,456 on 3DMark's Steel Nomad Light, and an AnTuTu GPU score of 1,031,655. Both results right about fall short of the Snapdragon 8 Elite and Dimensity 9400. The Snapdragon 8 Elite, for example, scores about 1,150,000 on AnTuTu's GPU test, and can hit a score of 2,584 on the Steel Nomad Light test as seen on the Oppo Find X8 Ultra.

Evidently, XRing O1 is a bonafide flagship chipset—it trades blows with the Snapdragon 8 Elite and Dimensity 9400 without being at a disadvantage. Unfortunately, XRing O1 is unlikely to ever make its way out of China officially. Those who wish to experience the chipset would be best served importing either the Xiaomi 15S Pro or Xiaomi Pad 7 Ultra, with neither of those devices currently scheduled to launch globally
