Display Comparison

While both phones likely feature high-quality AMOLED displays (data not provided), the focus here isn't on panel differences. The core distinction lies in the processing power driving the visuals. Both are expected to have 120Hz refresh rates, but the chipset's ability to maintain those high refresh rates during demanding tasks is key. The Snapdragon 8+ Gen 1's image signal processor (ISP) will impact image processing speed, but the Dimensity 9000+'s ISP is also highly capable.

Camera Comparison

Without detailed camera sensor information, a direct comparison is limited. However, both phones are expected to feature capable camera systems. The Snapdragon 8+ Gen 1's ISP is known for its excellent image processing, particularly in low-light conditions. The Dimensity 9000+ also has a powerful ISP, and Xiaomi's image processing algorithms will play a significant role in the final image quality. The real-world difference will likely be subtle, depending on Xiaomi's software tuning.

Performance

The Xiaomi 12 Pro (Dimensity) boasts a slight CPU clock speed advantage with its 3.20 GHz Cortex-X2 core compared to the 12S's 3.19 GHz core. More significantly, the Dimensity 9000+ features slightly faster Cortex-A710 cores (2.85 GHz vs 2.75 GHz). Both chips are built on a 4nm process, but the Dimensity 9000+ is generally regarded as more efficient, potentially leading to less thermal throttling under sustained load. The 12S benefits from Qualcomm's Snapdragon optimizations, but the Dimensity 9000+ often matches or exceeds the 8+ Gen 1 in benchmarks and real-world gaming.

Battery Life

Both devices share the same 67W wired charging capability, achieving a full charge in approximately 42 minutes. The 12S also offers 50W wireless charging and 10W reverse wireless charging, features absent in the 12 Pro (Dimensity). While battery capacity isn't specified, the Dimensity 9000+'s improved efficiency could translate to slightly longer battery life despite potentially similar capacities. The 12S's wireless charging is a significant advantage for users who prefer cable-free power-ups.

Buying Guide

Buy the Xiaomi 12S if you prioritize Qualcomm's ecosystem and potentially benefit from optimized software support for specific apps, and if you find it at a substantial discount. Buy the Xiaomi 12 Pro (Dimensity) if you want a more consistently powerful processor, potentially better sustained performance during extended gaming sessions, and are comfortable with MediaTek's silicon. Both phones offer excellent value, but the Dimensity variant edges ahead in raw power.

Frequently Asked Questions

❓ Does the Dimensity 9000+ in the 12 Pro overheat during prolonged gaming sessions?
The Dimensity 9000+ is known for its improved thermal efficiency compared to previous generations. While some throttling is inevitable during extended gaming, the 12 Pro (Dimensity) is generally expected to maintain higher frame rates for longer periods than devices with the Snapdragon 8+ Gen 1, particularly in demanding titles.
❓ Is the lack of wireless charging on the 12 Pro (Dimensity) a significant drawback?
For users who frequently utilize wireless charging, the absence of this feature on the 12 Pro (Dimensity) is a notable omission. However, the 67W wired charging is exceptionally fast, mitigating the inconvenience for many. If wireless charging is a must-have, the 12S is the clear choice.
❓ Will I notice a real-world performance difference between the Snapdragon 8+ Gen 1 and the Dimensity 9000+ in everyday tasks?
In typical daily usage – browsing, social media, video streaming – the performance difference between the two chipsets will be minimal and likely imperceptible. The benefits of the Dimensity 9000+ become more apparent during demanding tasks like gaming, video editing, and running multiple resource-intensive applications simultaneously.
