In a significant development ahead of Xiaomi’s May 22 event, a new Geekbench listing has surfaced that appears to show the upcoming Xiaomi 15S Pro powered by the company’s in-house Xring O1 chipset. The leaked benchmark results suggest that the chip may be far more powerful than early estimates, placing it close to Qualcomm’s top-tier Snapdragon 8 Gen 3 Elite and slightly ahead of MediaTek’s Dimensity 9400.

Xring O1 Benchmarks Raise Eyebrows

According to reliable leakers @UniverseIce and @Jukanlosreve, the device with model number 25042PN24C is believed to be the Xiaomi 15S Proa successor to the Snapdragon 8 Elite-powered Xiaomi 15 Pro. What makes this listing significant are its Geekbench scores—a multi-core score near 9,000 and single-core results ranging from the high-2,000s to low-3,000s. These numbers put it neck-and-neck with the best chips in the Android world.

While we haven’t seen official Xiaomi 15 Pro benchmarks, comparisons with the 15 Ultra and the known specs of competing chipsets indicate that Xring O1 is punching well above expectations.

Xring O1: Built on Advanced 3nm Node

Xiaomi has confirmed that the Xring O1 is built using a second-generation 3nm fabrication nodelikely contributing to its strong performance and efficiency. Though official architecture details remain under wraps, leaks suggest the following core configuration:

• 2 cores @ 3.90GHz

• 4 cores @ 3.40GHz

• 2 cores @ 1.89GHz

• 2 cores @ 1.80GHz

Interestingly, Geekbench recognizes the O1 as a 10-core CPUdiverging from the more typical 8-core configurations seen in recent flagship chips. While this could be an error in early software identification, it may also indicate a unique architecture strategy. The 3.90GHz peak clock speed is particularly notable—higher than even the Dimensity 9400+ (3.73GHz)—though still shy of the Snapdragon 8 Elite for Galaxy’s 4.47GHz.

Immortal-G925 GPU Surprises Observers

Contrary to earlier rumors suggesting an Imagination Technologies GPUthe Geekbench entry lists the Immortal-G925 GPUa premium design typically associated with flagship ARM chips. This shift adds further credibility to Xiaomi’s ambition of competing at the very top tier of mobile performance.

If legitimate, this would make the Xring O1 a serious competitor—not just for Qualcomm and MediaTek—but potentially for in-house chip leaders like Apple’s A-series as well.

May 22 Launch Event: What to Expect

All eyes are now on Xiaomi’s big launch event scheduled for May 22 (Thursday). The company is expected to unveil:

It is also widely believed this will mark the official debut of the Xring O1 chipsetconfirming whether the Geekbench results are representative of the final retail device.

A Strategic Shift in Xiaomi’s Playbook

With the launch of Xring O1, Xiaomi joins an elite club of OEMs developing their own mobile processors. This move positions the company for greater control over performance tuning, software optimization, and product differentiationparticularly important in high-end flagship segments.

If the Xring O1 lives up to its early promise, Xiaomi 15S Pro could set a new benchmark in the Android ecosystem—and redefine expectations from vertically integrated hardware platforms.
