On Monday,per erotice Xiaomi CEO Lei Jun posted on Chinese social platform Weibo: “In response to the rumors about the Xiaomi Xuanjie O1 (Xring O1) chip, please share this post.” Xiaomi clarified in the statement that the claim circulating online—that the Xuanjie O1 is a custom chip made by Arm—is false. The company stated that the chip was not custom-designed by Arm and that Arm’s CSS (Custom Silicon Solutions) services were not used during its development. That same evening, Arm updated its official press release, revising the previous “Custom Silicon” description to confirm that the Xuanjie O1 was independently developed by Xiaomi. Developed by Xiaomi’s in-house Xuanjie chip team, the Xuanjie O1 adopts the latest Armv9.2 Cortex CPU cluster IP, Immortalis GPU IP, and CoreLink system interconnect IP, and is fully compatible with advanced 3nm process technology.
