Xiaomi has introduced its first in-house chipset, the Xring O1, and it’s already looking like a threat to tech giants like Qualcomm and Apple.
The new Xiaomi Xring O1 is already used on the latest Xiaomi 15S Pro and Pad 7 Ultra. It is said to use CPU and GPU parts from ARM.
This chip is fabbed on the TSMC N3E node, similar to the MediaTek Dimensity 9400. The two also share other similar components like a Cortex-X925 core and an Immortalis-G925 GPU. Albeit they differ greatly in design.
The Xring O1 has not one, but two Cortex-X925 prime cores, two variants of the Cortex-A725, and two Cortex-A520 cores for extra efficiency.
Those two Cortex-A725 have two clusters, for a total of four. The first two are for high-performance tasks, while the latter have been optimized for efficiency. These two efficiency Cortex-A725 cores can be so efficient that the Cortex-A520 could be considered redundant.
The whole chip can reach clock speeds of up to 3.9GHz. It also has a unique on-chip memory designed with a lot of cache. There’s 16MB of L3 cache for all 10 cores, 4MB for the GPU, and 10MB for the NPU.
Oh, and by the way, the NPU is not from ARM and was designed by Xiaomi. They also designed the ISP themselves. Meanwhile, the GPU has a 16-core layout, which is really impressive.
Now, the question is, how does it fare with the completion?
Reports suggest that the Xring O1 beats the Dimensity 9400 in CPU performance and battery efficiency. It wasn’t able to overtake the Qualcomm Snapdragon 8 Elite, but it came really close.
The Xring O1 is only 109mm² in size, similar to the Apple A18 Pro. Both use external modems, which affects standby battery consumption. Apple addressed this by integrating the 5G modem on the iPhone 16e‘s A18 chip, a move Xiaomi should consider doing on the Xring O2.
