Xiaomi’s self-developed chipset hits the 2.5 million mark in early testing, matching Snapdragon 8 Elite-powered sibling

May 21, 2025 — Xiaomi’s push toward silicon self-reliance is starting to pay off. In a new AnTuTu benchmark leak shared by Weibo tipster Xiaomu Technology, the upcoming Xiaomi 15S Pro, powered by Xiaomi’s in-house Xring O1 chipset, has matched the performance of the Snapdragon 8 Elite-powered Xiaomi 15 Pro — both scoring around 2.5 million points in the synthetic benchmark.

This is a significant milestone for Xiaomi’s chipset division, marking a major leap from its earlier in-house efforts like the Surge S1. The Xring O1, now positioned to compete directly with top-tier offerings from Qualcomm and MediaTek, appears to be on par with the best Android has to offer in terms of raw performance.

Two Versions of the Xring O1: Flagship and Tablet Variant

Xiaomi seems to be using two versions of the Xring O1 SoC. The version found in the Xiaomi 15S Pro features two top-performance cores clocked at 3.9GHz, while a lower-clocked variant (3.7GHz) is used in the Xiaomi Pad 7 Ultra — likely for better thermal control in a larger form factor.

Hardware Setup Influenced the Score

While the scores are impressive, it’s important to note that the Xiaomi 15S Pro had a memory advantage: 16GB of RAM plus 6GB virtual RAM, compared to 12GB + 4GB on the 15 Pro. AnTuTu tests multiple aspects of a device, including memory and storage speed, which can affect final numbers beyond CPU/GPU performance alone.

Still, hitting the 2.5 million mark puts the Xring O1 on equal footing with today’s most powerful Android phones, a list that includes Snapdragon 8 Gen 3 Elite and Dimensity 9400 devices — many of which score in the 2.2–2.5 million range. For reference, devices like the Galaxy S25 Ultra and OnePlus 13 sit toward the lower end of that spectrum.

Xiaomi–Qualcomm Partnership Still Going Strong

Despite this leap in proprietary silicon, Xiaomi isn’t cutting ties with Qualcomm. The two companies have just signed a fresh agreement to co-develop and supply a wide range of future devices, including flagship smartphones, tablets, wearables, smart home gear, and XR headsets. Xiaomi also confirmed it will be among the first to adopt Qualcomm’s next-generation Snapdragon 8-series platform.

This suggests a dual-chip strategy, where Xiaomi leverages its Xring line for selected models while continuing to use Qualcomm chips for others — similar to Apple’s approach with M-series chips on Macs and A-series on iPhones.

Conclusion: A Promising Start for Xring

The Xiaomi 15S Pro’s performance in early benchmarks is a promising sign that the Xring O1 is a competitive flagship-grade SoC. With this debut, Xiaomi joins the likes of Apple, Samsung, and Huawei in developing its own high-performance chips, potentially giving it greater vertical control over performance, optimization, and innovation.

More detailed specs and thermal performance data will determine how well the chip holds up under real-world conditions, but the early signs point to a very capable debut.
