When Xiaomi said they were working on their own chip, most of us rolled our eyes. After all, we’ve seen this dance before. Big OEM announces custom silicon, promises the world, and then delivers… a lukewarm chip buried under marketing fluff. But the Xiaomi XRING O1? Well, this one might be different. It just might be the real deal.
Let’s break it down.
What is the Xiaomi XRING O1?
The XRING O1 (or Xuanjie O1) is Xiaomi’s first self-developed flagship SoC, officially launched in May 2025. It’s Xiaomi’s shot at joining the big boys in custom chipmaking—Apple with their Bionic, Samsung with Exynos, and Huawei with Kirin. Unlike its rivals who’ve had years to refine their silicon, this is Xiaomi’s first swing. But from the look of things, they didn’t just come to play—they came to compete.
This SoC is expected to debut in the upcoming Xiaomi 15S Pro and Xiaomi Pad 7 Ultra, and it’s got the specs to back the hype.

CPU & Performance
This chip comes fully loaded. Two Cortex-X925 cores at 3.9GHz? That’s pushing some serious performance. These are paired with four Cortex-A725 cores at 3.4GHz for sustained grunt, and four Cortex-A520 efficiency cores to keep things light when needed.
- 2x Cortex-X925 at 3.9 GHz (2 MB L2 cache per core)
- 4x Cortex-A725 at 3.4 GHz (1 MB L2 cache per core)
- 2x Cortex-A725 at 1.9 GHz (1 MB L2 cache per core)
- 2x Cortex-A520 at 1.8 GHz (512 KB L2 cache)
In terms of design, the XRING O1 is deca-core (10-core) that is at the bleeding edge of smartphone SoC tech. It is made using a second Gen 3nm TSMC process which should make it very efficient and battery friendly. As a result, it should rival the Snapdragon 8 Elite in terms of pure performance and outperform big names like the Dimensity 9400 Plus, Dimensity 9400, Apple A18 Pro, Apple A18, Snapdragon 8S Gen 4, Snapdragon 8 Gen 3 and Exynos 2400 etc. in raw CPU power based on current Geekbench scores. For a first-gen chip, this is shockingly good.
GPU
The XRING O1 features the Immortalis-G925 MP16, clocked at nearly 1.8GHz. This is one of ARM’s most powerful GPUs, and its inclusion here shows Xiaomi isn’t messing around.
You’re looking at smooth high-refresh gaming, desktop-class visuals, and hardware ray tracing all wrapped up in one neat package.
RAM and Storage
The use of LPDDR5T RAM and UFS 4.1 storage puts the XRING O1 in the top tier of modern mobile chips. These aren’t just specs on a sheet—they translate directly into real-world speed. Apps open instantly, multitasking is fluid, and load times shrink to nothing.
Benchmarks
- AnTuTu: Xiaomi has released an official score of just over 3 million, putting it right alongside the Snapdragon 8 Elite Gen 3 and better than the Dimensity 9400 plus.
- Geekbench 6: Early scores show 3017 (single-core) and 9264 (multi-core). This means that Xiaomi’s first Gen chip can rival the Snapdragon 8 Elite and outperform the Dimensity 9400 plus! This is crazy!
For a first Gen chip, Xiaomi have decided to go all out on this one and are already reaping the acclaim.
It is important to note however that independent reviewers have tested this SoC and say that it’s performance is somewhere around 2.7 million. This is a tad behind the 3 million that is claimed by Xiaomi. So we’ll watch this space as things unfold.
Display
XRING O1 supports resolutions up to WQHD, which should be more than enough for any modern smartphone or tablet. However, refresh rate support hasn’t been fully disclosed yet—so we’ll keep an eye out for 144Hz confirmation.
Camera and Video
Xiaomi has equipped the XRING O1 with a powerful ISP that can handle up to 200MP sensors and record at 4K @60fps. While it doesn’t push into 8K territory like Qualcomm or MediaTek’s best, 4K60 is still the sweet spot for quality and usability.
Connectivity
The XRING O1 supports 5G sub-6GHz and mmWave, 4G LTE Cat 24, Bluetooth 5.4, and WiFi 6. It’s not bleeding edge (no WiFi 7 yet), but it’s not lacking either. This will provide stable, high-speed connectivity across the board.
Final Thoughts
Xiaomi has entered the custom chip arena with a bang. The XRING O1 may not dethrone the Snapdragon 8 Elite, but it comes very, very close. This is an ambitious and impressive first effort.
It outperforms Apple A18 Pro, competes toe-to-toe with the Dimensity 9400 Plus, and only trails behind Qualcomm’s flagship (8 Elite) by a hair. And this is just the first-gen version.
Caution: These results are still based on early leaks, and things could change. We’ll keep updating this page as more details emerge.
TL;DR
The XRING O1 is Xiaomi’s first custom flagship chip—and it’s no joke. With Cortex-X925 cores, Immortalis GPU, LPDDR5T, and UFS 4.1, it’s built for speed. Benchmarks place it alongside the Snapdragon 8 Elite, while surpassing Dimensity 9400 plus. This is the most exciting first-gen chip we’ve seen in years.
