Almost a year ago, Xiaomi introduced the Xiaomi 15S Pro, the first phone to be powered by an in-house chipset called the Xring O1. It was a variant of the Xiaomi 15 Pro, which originally ran on the Snapdragon 8 Elite. According to the report of Yogesh Brar, the company is thinking of doing something similar this year also.
The problem is that there will be a version of the Xiaomi 18 Ultra powered by the Xring O3. This is the next-generation Ultra, which should arrive in December – according to Brar, the company is not planning a global release for the Xring-based model, so it will only be available in China.
Details on Xring O3 (Lhasa)
recently, xitime Interesting information surfaced about the Xring O3 (code name “Lhasa”) – Xiaomi has redesigned the CPU and increased the GPU clock speed.
The Xring O1 had an interesting four-tier CPU architecture with two Cortex-X925 cores, two Cortex-A725 cores, then four lower-clocked A725 cores and two Cortex-A520 cores. These groups were labeled “prime”, “titanium”, “large” and “small”.
For the Xring O3, Xiaomi will remove the “large” tier. However given the clock speed employed, it seems more accurate to say that the “small” level will play the role of the “large” level. Here’s an analysis:
| Xring O1 | Xring O3 | |
|---|---|---|
| main | 2x Cortex-X925 3.89GHz |
4.05GHz |
| titanium | 2x Cortex-A725 3.39GHz |
3.43GHz |
| Big | 4x Cortex-A725 1.89GHz |
– |
| Little | 2x Cortex-A520 1.79GHz |
3.02GHz |
| gpu | Immortalis-G925 MP16 1.2ghz |
1.5ghz |
| DDR | 9,600MT/s | 9,600MT/s |
As you can see, the new “Prime” cores – we don’t know the core count yet – will break the 4GHz barrier. And the “small” core will be clocked significantly higher than the old “big” and “small” cores.
Additionally, Xiaomi will boost the GPU speed to 0.3GHz. That means an increase of 25%. The GPU design is unknown, but it will likely be an ARM Mali G1-Ultra (the successor to the G925). Similarly, the CPU cores are probably ARM C1 cores. However, the RAM speed will remain the same.
A few weeks ago, a leak suggested that the Xring O3 would launch alongside the Xiaomi Mi Mix Fold 5, which is expected to launch in August. Still, using its in-house chipset in more phones is a big deal – the O1 was only featured in the Xiaomi 15S Pro and two tablets (Xiaomi Pad 7 Ultra and Xiaomi Pad 7S Pro 12.5).
