When we test new flagship smartphones, performance isn’t just a number we glance at once and forget. It’s one of the clearest indicators of how well a phone will handle real-world demands like high-end gaming, 4K video editing, heavy multitasking, and long-term software updates. That’s why our reviews routinely include a deep performance check using multiple benchmarks, including Geekbench, which is widely used to measure CPU power.
In the latest round of testing, the Xiaomi 17 Ultra comes out ahead of the Xiaomi 17 Pro Max in Geekbench CPU results. On paper, that makes the Ultra look like the clear performance winner. But benchmark scores never tell the whole story unless you also look at what it takes to achieve them.
Once power consumption enters the picture, the gap becomes much easier to understand. Our measurements show the Xiaomi 17 Ultra is drawing significantly more power than its sister model—nearly double in this comparison. In other words, the Ultra isn’t just slightly better optimized; it’s being allowed to run harder.
This points to a strategy manufacturers often use with “Ultra” branding: the top-tier model is tuned to push the chipset closer to its maximum capability, even if that means higher power draw. Meanwhile, the other model—despite using similar hardware—may be set up with stricter limits to prioritize efficiency, lower heat output, or battery endurance.
The takeaway is simple: the Xiaomi 17 Ultra is delivering higher CPU performance because it’s consuming more power to do it. That likely means the Ultra model has fewer restrictions on how aggressively it can boost and sustain peak performance, letting the system-on-chip operate closer to its full potential.
If you’re deciding between the two, this contrast matters. The Xiaomi 17 Ultra may be the better pick for users who want the strongest possible performance, while the Pro Max may appeal to those who value efficiency and potentially cooler, steadier behavior under long workloads.
