About a year ago, Xiaomi introduced the Xiaomi 15S Pro, its first phone to be powered by an in-house chipset, which was called the Xring O1. This was a variant of the Xiaomi 15 Pro, which originally ran on a Snapdragon 8 Elite. The company may be looking to do something similar this year, reports Yogesh Brar.
The scuttlebutt is that there will be a version of the Xiaomi 18 Ultra powered by the Xring O3. That’s the next generation Ultra, which should arrive in December – according to Brar, the company isn’t planning on a global release for the Xring-based model, so it will be available only in China.
Details on the Xring O3 (Lhasa)
Recently, Ximitime uncovered interesting info about the Xring O3 (code name “Lhasa”) – Xiaomi has redesigned the CPU and boosted the GPU clock speed.
The Xring O1 had an interesting four-tier CPU structure with two Cortex-X925 cores, two Cortex-A725 cores, then four lower-clocked A725 cores and two Cortex-A520 cores. These clusters were labeled “prime”, “titanium”, “big” and “little”.
For the Xring O3, Xiaomi will do away with the “big” tier. Although looking at the planned clock speeds, it seems more accurate to say that the “little” tier will be taking over the role of the “big” tier. Here’s a breakdown:
| Xring O1 | Xring O3 | |
|---|---|---|
| Prime | 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 counts yet – will crack the 4GHz barrier. And the “little” cores will be clocked significantly higher than the old “big” and “little” cores.
Also, Xiaomi will bump up the GPU speed by 0.3GHz. That is an increase of 25%. The GPU design is unknown, but chances are that it will be an ARM Mali G1-Ultra (the successor to the G925). By the same token, the CPU cores are likely ARM C1 cores. The RAM speed will remain the same, however.
A few weeks ago, a leak suggested that the Xring O3 will debut with the Xiaomi Mix Fold 5, which is expected to debut in August. Still, using its in-house chipset in more phones is a big deal – the O1 was featured only in the Xiaomi 15S Pro and two tablets (Xiaomi Pad 7 Ultra and Xiaomi Pad 7S Pro 12.5).
