  • More refined overall experience

  • Slower 67W charging compared to the GT Neo 3
  • Likely higher price tag

Display Comparison

The Realme GT Neo 3 boasts a display capable of reaching 796 nits of peak brightness, ensuring good visibility outdoors. However, the Xiaomi 12 Pro’s display specifications are not provided, suggesting a potentially higher peak brightness based on its flagship positioning. While both displays have an 'Infinite' contrast ratio (a marketing term), the real-world difference will likely hinge on color accuracy and panel technology, which are currently unknown for the Xiaomi 12 Pro. The absence of LTPO information for either device suggests neither offers adaptive refresh rate technology for optimal power efficiency.

Camera Comparison

Both devices are listed with 'Photo / Video' capabilities, lacking specific details. However, the Xiaomi 12 Pro’s flagship status suggests a more sophisticated camera system, potentially with a larger sensor and more advanced image processing algorithms. Without sensor size or aperture information, it’s difficult to make a definitive judgment. The Realme GT Neo 3 likely focuses on delivering good value, while the Xiaomi 12 Pro aims for higher image quality and versatility. The absence of details on OIS (Optical Image Stabilization) for either device is a notable omission.

Performance

The core difference lies in the chipsets: the Realme GT Neo 3 utilizes the Mediatek Dimensity 8100 (5nm), while the Xiaomi 12 Pro (Dimensity) features the more advanced Dimensity 9000+ (4nm). The 9000+ boasts a prime Cortex-X2 core clocked at 3.20 GHz, significantly exceeding the GT Neo 3’s Cortex-A78 cores at 2.85 GHz. This translates to a noticeable performance advantage in demanding tasks and sustained workloads. The 4nm process of the 9000+ also offers improved thermal efficiency compared to the 5nm 8100, potentially reducing throttling during extended gaming sessions. The Xiaomi 12 Pro’s CPU configuration (1+3+4) is also more modern than the Realme’s (4+4), indicating a more sophisticated approach to task allocation.

Battery Life

The Realme GT Neo 3’s 80W wired charging is its standout feature, achieving a full charge in just 32 minutes. The Xiaomi 12 Pro offers 67W wired charging with PD3.0 and QC4 support, which is still fast but significantly slower. While battery capacity isn’t specified for either device, the faster charging of the GT Neo 3 mitigates the impact of a potentially smaller battery. Users who frequently top up their phones will greatly benefit from the GT Neo 3’s charging speed.

Buying Guide

Buy the Realme GT Neo 3 if you absolutely need the fastest possible charging speeds and prioritize gaming performance on a budget. Its 80W charging gets you from 0-100% in just 32 minutes, and the Dimensity 8100 is no slouch. Buy the Xiaomi 12 Pro (Dimensity) if you prefer a more polished, premium experience with a more powerful processor, potentially better camera processing, and a more balanced feature set, even if it means slightly slower charging.

Frequently Asked Questions

❓ Does the Dimensity 9000+ in the Xiaomi 12 Pro get noticeably hotter than the Dimensity 8100 in the Realme GT Neo 3 during prolonged gaming?
While both chips are efficient, the Dimensity 9000+’s higher performance ceiling means it will generate more heat under sustained load. However, the 4nm process node and Xiaomi’s thermal management system should mitigate this, preventing significant throttling. The Realme GT Neo 3, while cooler, may experience more performance drops during extended gaming sessions due to its less powerful chipset.
❓ Is the 67W charging on the Xiaomi 12 Pro still useful, or is the 80W on the Realme GT Neo 3 a must-have?
67W charging is still very fast and will fully charge the phone in a reasonable timeframe. However, the 80W charging on the Realme GT Neo 3 is significantly quicker, shaving off valuable minutes. If you frequently find yourself needing to quickly top up your phone, the 80W charging is a substantial advantage.
❓ Given the lack of detailed camera specs, should I assume the Xiaomi 12 Pro has a significantly better camera?
It's a reasonable assumption. Xiaomi typically invests heavily in its flagship camera systems. While we lack concrete details, the 12 Pro’s positioning suggests a larger sensor, more advanced image processing, and potentially features like OIS that the GT Neo 3 may not have. However, image processing preferences are subjective, so real-world samples are crucial for a final assessment.
