Display Comparison
Both devices feature displays with an 'Infinite' contrast ratio, typical of modern OLED panels. However, the Asus ROG Phone 7 Ultimate edges out the Xiaomi 12T with a measured peak brightness of 1095 nits compared to the 12T’s 954 nits, resulting in better visibility in direct sunlight. While neither manufacturer specifies refresh rates in the provided data, the ROG Phone series historically prioritizes high refresh rates for smoother gaming, a likely advantage here. The ROG Phone 7 Ultimate’s larger size also allows for a more immersive viewing experience.
Camera Comparison
Both phones are listed as having 'Photo / Video' capabilities, but lack specific details. Without sensor size or aperture information, a direct comparison is difficult. However, given the ROG Phone’s gaming focus, its camera system is likely optimized for quick snapshots and streaming, while the Xiaomi 12T may prioritize more versatile photography features. The absence of details suggests neither phone is a standout in the camera department, focusing instead on their primary strengths.
Performance
The core difference lies in the chipsets. The Asus ROG Phone 7 Ultimate’s Qualcomm Snapdragon 8 Gen 2 (4nm) significantly outperforms the Xiaomi 12T’s MediaTek Dimensity 8100 Ultra (5nm). The Snapdragon 8 Gen 2’s newer architecture – featuring a Cortex-X3 prime core – and smaller 4nm process node translate to higher clock speeds (3.2 GHz vs 2.85 GHz) and improved thermal efficiency. This means the ROG Phone 7 Ultimate will sustain peak performance for longer periods during demanding tasks like gaming, experiencing less throttling. The ROG Phone also benefits from a more modern CPU core configuration, with Cortex-A715 and A710 cores versus the 12T’s A78 and A55.
Battery Life
The Asus ROG Phone 7 Ultimate boasts a superior endurance rating of 131 hours compared to the Xiaomi 12T’s 104 hours. This difference is likely due to the Snapdragon 8 Gen 2’s improved power efficiency and potentially a larger battery capacity (not specified). While the Xiaomi 12T compensates with incredibly fast 120W wired charging (0-100% in 19 minutes), the ROG Phone 7 Ultimate’s 65W charging (42 minutes) is slower. The ROG Phone also offers 10W reverse wired charging, a feature absent on the 12T, allowing it to top up accessories.
Buying Guide
Buy the Xiaomi 12T if you need a versatile smartphone with excellent charging speeds and a bright display for everyday tasks and casual gaming. It’s ideal for users who want flagship-level features without the premium gaming-focused price tag. Buy the Asus ROG Phone 7 Ultimate if you prioritize uncompromising gaming performance, extended battery life during intense sessions, and a feature set tailored specifically for mobile esports – even if it means sacrificing some charging speed and paying a premium.
