Xiaomi Poco F8 Ultra
- Significantly faster charging (100W vs 65W)
- Potentially superior CPU performance with Snapdragon 8 Elite Gen 5
- More versatile wireless charging options (50W vs 10W)
- Camera specifications are unknown, potentially lagging behind competitors
- Gaming-specific features are less developed than the ROG Phone 7 Ultimate
Asus ROG Phone 7 Ultimate
- Optimized for gaming with dedicated features (AirTriggers, cooling)
- Slightly higher peak display brightness
- Established gaming software ecosystem
- Slower charging speed (65W)
- Snapdragon 8 Gen 2 is a generation behind the Poco F8 Ultra’s chipset
- Limited reverse charging capabilities
Display Comparison
Both devices feature excellent displays, with the ROG Phone 7 Ultimate achieving a slightly higher measured peak brightness of 1095 nits compared to the Poco F8 Ultra’s 1077 nits. While the difference is minimal, the ROG Phone 7 Ultimate’s ‘Infinite’ contrast ratio (nominal) suggests superior black levels. Neither specification details refresh rate or panel technology (LTPO), but given the target market, both are likely to offer high refresh rates. The real-world impact will depend on the quality of calibration and color accuracy, which requires further testing.
Camera Comparison
Context data for both devices is limited to 'Photo / Video'. Without sensor size, aperture, or OIS details, a meaningful comparison is difficult. However, given Asus’s history with ROG Phones, the camera is likely a secondary consideration, focusing on adequate performance rather than pushing boundaries. The Poco F8 Ultra, positioned as a flagship, may prioritize camera capabilities more, but this remains speculative without further information. The absence of detail suggests neither phone will be a standout camera performer.
Performance
The core differentiator lies in the chipsets. The Poco F8 Ultra’s Snapdragon 8 Elite Gen 5 (3nm) boasts an octa-core configuration with a unique split: 2x4.6 GHz Oryon V3 Phoenix L cores and 6x3.62 GHz Oryon V3 Phoenix M cores. This contrasts with the ROG Phone 7 Ultimate’s Snapdragon 8 Gen 2 (4nm) which uses a more traditional Cortex-X3, A715, A710, and A510 arrangement. The 3nm process of the Snapdragon 8 Elite Gen 5 should deliver superior power efficiency and thermal performance, allowing for sustained peak performance. The Poco F8 Ultra’s CPU clock speeds are significantly higher, suggesting a raw performance advantage in CPU-bound tasks. However, the ROG Phone 7 Ultimate benefits from Asus’s extensive thermal management system, potentially mitigating throttling under sustained load.
Battery Life
The Poco F8 Ultra delivers a compelling battery and charging package. Its active use score of 18:52h is a strong indicator of endurance. Crucially, it supports 100W wired charging, achieving a full charge in just 38 minutes, alongside 50W wireless and 22.5W reverse wireless. The ROG Phone 7 Ultimate, while boasting a 131h endurance rating (likely a standby rating), is limited to 65W wired charging, taking 42 minutes to reach 100%. The Poco F8 Ultra’s faster charging is a significant advantage for users who prioritize convenience. The 10W reverse wired charging on the ROG Phone 7 Ultimate is also considerably slower than the Poco’s offering.
Buying Guide
Buy the Xiaomi Poco F8 Ultra if you need the absolute fastest Android processor available, prioritize rapid charging speeds, and value a high-brightness display for everyday use. Buy the Asus ROG Phone 7 Ultimate if you are a serious mobile gamer who benefits from dedicated gaming features like AirTriggers, optimized cooling, and a software ecosystem tailored for competitive play.
