Which should you buy?
The Xiaomi 16 Ultra edges ahead on the Mars Score (67.6 vs 74.3), but the 6.7-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the V40 Pro if you photograph or shoot video regularly and want the better imaging pipeline of the two. The biggest gaps in its favor are front camera, weight, screen size.
Pick the Xiaomi 16 Ultra if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. Its strongest claims are antutu, ram, wired charging, among others.
Both ship with comparable main camera, refresh rate, 5g support, so those specs don't separate the two — focus on the differences below.
Bottom line: the Xiaomi 16 Ultra is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
