Xiaomi has arrived with a bang and now the flagship mobile processor space is hotter than ever. With Apple refining its custom silicon and Xiaomi stepping up with its first self-developed chip, we now have a serious showdown on our hands. In this comparison of Xring O1 vs Apple A18 Pro, we’ll compare two of the some of the most powerful smartphone SoCs available today. One represents Apple’s tried-and-tested vertical integration, the other is Xiaomi’s bold step into chip development. So, how do they stack up?
Xiaomi Xring O1: A New Challenger
The Xring O1 is Xiaomi’s first in-house flagship processor, announced in May 2025. Manufactured on TSMC’s 2nd Gen 3nm process, the Xring O1 is designed for premium flagship performance. It features a 10-core CPU, a powerful Immortalis GPU, and supports bleeding-edge memory, storage, and connectivity. You’ll find this chip in high-end Xiaomi devices like the Xiaomi 15S Pro and Xiaomi Pad 7 Ultra.
Apple A18 Pro: Tried, Tested, and Refined
The Apple A18 Pro is Apple’s latest mobile chipset, launched in September 2024 alongside the iPhone 16 Pro and 16 Pro Max. It’s built on TSMC’s 1st Gen 3nm process, and despite having fewer cores than its rival, it delivers blistering single-core performance. The A18 Pro integrates Apple’s custom CPU and GPU architecture, and benefits from Apple’s tightly integrated ecosystem.

CPU cores
The Xring O1 sports a 10-core CPU layout using ARM’s latest Cortex-X925 and A725 cores. Its performance cores are clocked up to 3.9GHz, giving it a clear advantage in multi-core workloads. Meanwhile, Apple’s A18 Pro sticks to a 6-core design (2 high-performance Everest + 4 efficiency Sawtooth).
When it comes to performance, Apple’s A18 Pro comes out on top for single-core tasks, whilst the Xiaomi XRING O1 wins on multi-core tests.
- Multicore Winner: Xring O1
- Single-core Winner: Apple A18 Pro
GPU performance
The Immortalis-G925 in the Xring O1 runs at a sharp 1392MHz and boasts more shader cores than Apple’s custom GPU (estimated 5–6 cores, 1490MHz). On paper, Xiaomi has the more powerful GPU. However, Apple’s GPU may benefits from more optimization and better thermal efficiency in the iPhone chassis. So:
- Raw Power: Xring O1
- Optimization: Apple A18 Pro
Benchmarks
On AnTuTu, the Xiaomi Xring O1 (~2.7M) crushes the A18 Pro (~1.8M) in total score—thanks to higher GPU, RAM, and storage throughput. On GeekBench 6, Apple wins single-core (3582 vs 3017), Xiaomi wins multi-core (9264 vs 9090).
So, depending on the benchmark:
- Single-Core Tasks: Apple A18 Pro
- Overall & Multi-Core: Xring O1
RAM & Storage
The Xring O1 uses LPDDR5T RAM running at 4800MHz, which is faster than Apple’s LPDDR5X at 3750MHz. Xiaomi also supports UFS 4.1, while Apple sticks to its usual NVMe storage.
- RAM Speed: Xring O1
- Storage: Comparable (NVMe vs UFS 4.1)
Display Support
Both chips support WQHD displays, with no official support for 4K screens. It’s a tie here.
Winner: Draw
Camera & Video
The Xring O1 supports up to 200MP sensors and 8K video at 30fps, while the A18 Pro tops out at 48MP and 4K@120fps. Apple compensates with its custom ISP and image processing pipeline, but in terms of raw sensor support:
- Hardware Flexibility: Xring O1
- Real-World Quality: Apple A18 Pro (subjective, based on implementation)
Connectivity & Communications
- Modem: A draw—both support 5G Sub-6 and mmWave at Cat 24 speeds.
- Bluetooth: Xiaomi offers v5.4, Apple has v5.3.
- WiFi: Both chips support WiFi 7.
- Winner: Slight edge to Xring O1 for newer Bluetooth
Conclusion
The Xiaomi Xring O1 vs Apple A18 Pro battle is a tale of two philosophies. Apple’s A18 Pro dominates in single-core efficiency, tight ecosystem integration, and real-world balance. But the Xring O1 brings brute-force power, more cores, higher GPU frequency, and better memory bandwidth—making it a compelling flagship alternative, especially in multi-threaded and gaming scenarios.
Verdict:
- For iOS users and those who value battery life and app optimization, the A18 Pro is unmatched.
- For power users, gamers, and multitaskers, the Xring O1 is the more powerful and flexible choice.
Both SoCs are brilliant—but serve different audiences.
