Another Xiaomi product, a tablet, uses this chip. They say the performance of it is surprisingly really good!
Xiaomi unveiled last week the Xiaomi 15S Pro. The phone is identical to its sibling, the Xiaomi 15 Pro, in every other aspect except for one. It uses the in-house XRing O1 Chip. This means you’re getting almost the same components including the display, battery life, charging, and cameras. Xiaomi is trying to be as self-reliant as possible and to start that, they developed their own chipset which could power their current and future devices.
This isn’t the first time Xiaomi attempted to design a chipset for themselves. The first time was the Surge S1 which was released as a midrange chip back in 2017. It’s safe to say they have experience in designing a chip. It’s just that they relied heavily on Qualcomm and MediaTek that the XRing O1 is such a big news. Maybe it’s time for Xiaomi to start using their own designs again?
While designed by Xiaomi, the XRing O1 uses an ARM architecture and it is fabricated by a 2nd generation 3nm TSMC process. In essence, it’s an ARM chipset and a glorified MediaTek Dimensity 9400.
The XRing O1 is a deca-core chipset comprising of two Cortex-X925 Prime CPU cores clocked at 3.9GHz, four Cortex-A725 Big Cores clocked at 3.4GHz, another set of two Cortex-A725 cores cloeked at 1.9GHz, and two Cortex-A520 efficiency cores clocked at 1.8GHz. Deca-core chips are rare in the industry because it destroys the balance between good thermal conduction and performance. The MediaTek X10 for example, was notorious for heating up like crazy. However, that was over ten years ago and technology has evolved since. Advancements in thermal conduction, such as large vapor chamber and liquid cooling, have made it possible for deca-core chipsets to return.
The XRing O1 supports LPDDR5 RAM, UFS 4.1 storage, and USB 3.2 Gen2 connectivity.
This development made the XRing O1 a chipset worthy of competing against the Qualcomm Snapdragon 8 Elite and the MediaTek Dimensity 9400, as if the Kirin chipsets we knew and loved came back to life. The chipset managed to reach a score of around 3 million in AnTuTu and 3000 single core and 9000 multi-core score points over at Geekbench which blows the Apple A18 Pro out of the water. Yes, it is that powerful theoretically. Performance wise, it is only slightly behind the Qualcomm Snapdragon 8 Elite and only slightly ahead of the MediaTek Dimensity 9400.
One drawback of the XRing O1 chip is that it lacks an integrated modem, opting to use MediaTek’s T800. Developing an integrated modem inside a chipset takes years, so this is considerable.
As per GizmoChina‘s review, the chipset’s temperature and performance are stable and does not throttle hard on demanding games such as Honkai: Star Rail and Genshin Impact and its overall efficiency is excellent.
The Xiaomi 15S Pro is not available yet outside of China, where it starts at CNY 5,499 (~PHP 42.6K) (16/512). It comes in Black and Blue. As of this day’s writing, no global release has been announced.
