ROG Phone 9 vs Xiaomi 15 Ultra
A side-by-side readout for antutu.
Understanding antutu
AnTuTu produces a single number summarizing a device's overall performance. Subscores break down CPU, GPU, memory bandwidth, and UX (touch latency, animation smoothness).
What it captures well
Cross-vendor ranking for general performance. A phone scoring 2,500,000 will feel faster in everyday use than one scoring 1,500,000.
What it doesn't
- Sustained thermal performance. A 5-minute AnTuTu run won't show throttling that bites during 30 minutes of gaming.
- Real-app performance. Some apps are CPU-bound, others GPU-bound. The composite score blurs the distinction.
- Cross-OS comparisons. AnTuTu scores between iOS and Android are not directly comparable due to OS-level differences in measurement.
For a truer picture, look at AnTuTu + Geekbench (single + multi) + 3DMark (graphics) together. Each captures something the others miss.
This matchupXiaomi 15 Ultra's 2720000 is roughly 5% higher than ROG Phone 9's 2580000 (a 140000 gap). Whether that gap is noticeable depends on workload — small percentage gaps rarely change day-to-day experience, while gaps of 20% or more usually do.
What is antutu?
A widely-cited cross-platform smartphone benchmark that combines CPU, GPU, memory, and UX tests into a single composite score. Useful as a rough ranking, less so for granular comparison.
