Xiaomi is having an event later this week that will bring a number of high-profile new products. Lei Jun, CEO and founder, now confirmed on social media that Xiaomi 15S Pro smartphone and the Xiaomi Pad 7 Ultra tablet will be among them and both will be powered by the Xring O1 chipset, developed in-house.
The platform, built on the 3nm process, will also be officially introduced, even if the chip already appeared on Geekbench.
Xiaomi 15S Pro • Pad 7 Ultra • Xring O1
Lei Jun shared on his Weibo profile that the chip is already in mass production. Xiaomi invested CNY 13.5 billion (about $2 billion) in its development, and the plan is to bring at least CNY 50 billion more in chip design over the next 10 years.
According to a Geekbench listing, the O1 will have a 10-core CPU (which might be a mistake by the testing software, a common one with new chips). The top cluster will reach 3.90 GHz, while the GPU is Immortalis-G925.
Xiaomi 15 Ultra
If the benchmark results are representative of the final performance (which is not a given at this early stage), the Xring O1 should outperform the Snapdragon 8 Elite in the Xiaomi 15 Ultra, both in single core and multiple core tasks.
