- May throttle more under sustained load compared to the 888+
Asus ROG Phone 5s Pro
- More powerful Snapdragon 888+ chipset
- Superior thermal management for sustained performance
- Brighter display for outdoor visibility
- Slower 65W charging compared to the iQOO 8
- Higher price tag
Display Comparison
While both phones feature high refresh rate displays, the Asus ROG Phone 5s Pro boasts a measured peak brightness of 840 nits, suggesting a more visible experience in direct sunlight. The iQOO 8’s display specifications are not provided, making a direct comparison difficult, but the ROG Phone’s higher brightness is a clear advantage for outdoor use. Both likely utilize AMOLED panels for vibrant colors, but the ROG Phone’s brightness gives it an edge in usability.
Camera Comparison
Detailed camera specifications for the iQOO 8 are unavailable, hindering a comprehensive comparison. However, the ROG Phone 5s Pro’s camera system is geared towards versatility. While sensor sizes and apertures are unknown for the iQOO 8, the ROG Phone’s focus on gaming suggests its camera is a secondary consideration. Without further data on the iQOO 8’s camera, it’s difficult to assess its image quality relative to the ROG Phone.
Performance
The Asus ROG Phone 5s Pro’s Snapdragon 888+ 5G chipset, clocked at 2.99 GHz, represents a refinement over the iQOO 8’s Snapdragon 888 (2.84 GHz). The ‘+’ variant offers incremental improvements in CPU and GPU clock speeds, leading to slightly better performance in demanding tasks. Crucially, the 888+ also benefits from improved thermal efficiency, potentially reducing throttling during prolonged gaming. Both devices utilize an octa-core configuration with the same Cortex-A78 and A55 cores, but the higher clock speed of the X1 core in the ROG Phone 5s Pro provides a tangible performance boost.
Battery Life
Both the iQOO 8 and ROG Phone 5s Pro achieve an endurance rating of 110 hours, indicating similar overall battery life. However, their charging capabilities differ dramatically. The iQOO 8’s 120W wired charging is significantly faster than the ROG Phone 5s Pro’s 65W charging, capable of fully charging the device in a fraction of the time (estimated 52 minutes for the ROG Phone vs. potentially under 20 for the iQOO 8). The ROG Phone 5s Pro also supports PD3.0, QC5, and 10W reverse wired charging, offering greater compatibility and convenience, but it cannot match the iQOO 8’s sheer charging speed.
Buying Guide
Buy the vivo iQOO 8 if you need the absolute fastest charging speeds available and are willing to trade a small amount of sustained gaming performance for it. It’s ideal for users who frequently top up their battery throughout the day. Buy the Asus ROG Phone 5s Pro if you prioritize extended gaming sessions, a more refined gaming experience with features like AirTriggers, and a slightly more powerful processor capable of maintaining higher frame rates for longer periods.
