Display Comparison

The Asus ROG Phone 7 Ultimate boasts a display capable of reaching 1095 nits of peak brightness, ensuring excellent visibility even in bright outdoor conditions. While the Black Shark GS3 Ultra’s display specifications are currently unknown, a flagship gaming phone would be expected to match or exceed this brightness level. The ROG Phone’s infinite contrast ratio, typical of AMOLED panels, delivers deep blacks and vibrant colors. The absence of information regarding the GS3 Ultra’s panel type (LTPO or standard AMOLED) and refresh rate makes a direct comparison difficult, but a high refresh rate is crucial for smooth gaming visuals on both devices.

Camera Comparison

Both phones feature photo and video capabilities, but the emphasis for both is clearly not on photography. Without specific details on the Black Shark GS3 Ultra’s camera system, it’s difficult to make a direct comparison. The ROG Phone 7 Ultimate likely prioritizes functional camera performance over flagship-level image quality. The inclusion of Optical Image Stabilization (OIS) on the ROG Phone would be a significant advantage for video recording, reducing shake and improving stability. The presence of a 2MP macro camera on either device is largely irrelevant for most users.

Performance

Both devices are powered by the Qualcomm SM8550-AB Snapdragon 8 Gen 2 (4 nm) chipset, featuring an Octa-core CPU configuration (1x3.2 GHz Cortex-X3, 2x2.8 GHz Cortex-A715, 2x2.8 GHz Cortex-A710, 3x2.0 GHz Cortex-A510). This ensures comparable raw processing power. However, the ROG Phone 7 Ultimate’s thermal management system is well-documented, utilizing advanced cooling solutions to prevent throttling during extended gaming sessions. The Black Shark GS3 Ultra’s thermal design remains a key unknown; effective cooling is paramount to sustaining peak performance. The ROG Phone’s LPDDR5x RAM configuration further contributes to its responsiveness and multitasking capabilities.

Battery Life

The Asus ROG Phone 7 Ultimate achieves an impressive endurance rating of 131 hours, indicating excellent battery life. Its 65W wired charging, supporting PD3.0 and QC5, allows for a full charge in approximately 42 minutes. The 10W reverse wired charging is a useful addition for topping up accessories. The Black Shark GS3 Ultra’s battery capacity and charging speed are currently unknown. To compete effectively, it would need to offer comparable or faster charging speeds and a battery capacity sufficient to support extended gaming sessions.

Buying Guide

Buy the Xiaomi Black Shark GS3 Ultra if you need a potentially more affordable high-performance gaming phone and are willing to accept some uncertainty regarding long-term software support and thermal management. Buy the Asus ROG Phone 7 Ultimate if you prefer a refined, feature-rich gaming experience with a proven track record, excellent battery life, and a comprehensive ecosystem of gaming accessories. The ROG Phone is the safer bet for serious gamers.
