Asus ROG Phone 9

  • Exceptional sustained gaming performance with Snapdragon 8 Elite
  • Long battery life (16:41h active use)
  • More compact and manageable size for gaming
  • Gaming-focused features and optimizations

  • Older chipset generation (Snapdragon 8 Elite vs Gen 3)
  • Slower charging speed compared to iQOO 12 Pro

vivo iQOO 12 Pro

  • Latest Snapdragon 8 Gen 3 chipset
  • Blazing-fast 120W wired charging
  • 50W wireless charging
  • Potentially superior camera system

  • May experience more thermal throttling under sustained load
  • Potentially larger and less comfortable for extended gaming

Display Comparison

The Asus ROG Phone 9 boasts a bright display, reaching a measured 1958 nits peak brightness, ensuring excellent visibility even in direct sunlight. While the iQOO 12 Pro’s display specs aren’t provided, iQOO typically employs high-quality AMOLED panels. The ROG Phone 9’s focus on gaming likely includes a high touch sampling rate and low latency, crucial for competitive play. The absence of LTPO information for either device means we can’t definitively assess adaptive refresh rate efficiency, but the ROG Phone’s gaming optimizations likely prioritize consistent refresh rates over power savings.

Camera Comparison

Detailed camera specifications for both devices are limited. However, given the market positioning, the iQOO 12 Pro likely prioritizes camera capabilities more heavily. iQOO phones often feature large sensors and advanced image processing. The ROG Phone 9, while capable, typically focuses less on camera prowess, prioritizing gaming features. Without specific sensor size or aperture information, it’s difficult to make a definitive comparison, but the iQOO 12 Pro is likely to offer a more versatile and feature-rich camera system.

Performance

The core difference lies in the chipsets. The Asus ROG Phone 9 utilizes the Qualcomm SM8750-AB Snapdragon 8 Elite (3nm), featuring a unique octa-core configuration with Oryon V2 Phoenix cores clocked up to 4.32 GHz. This architecture is designed for sustained performance, crucial for long gaming sessions. The iQOO 12 Pro, conversely, employs the Snapdragon 8 Gen 3 (4nm). While the Gen 3 offers improvements in AI processing and overall efficiency, its clock speeds (3.3 GHz Cortex-X4) are lower than the ROG Phone 9’s Oryon cores. The 3nm process of the Snapdragon 8 Elite should translate to better thermal efficiency, potentially reducing throttling under heavy load. The iQOO 12 Pro benefits from the newer architecture, but the ROG Phone 9’s specialized chipset is geared towards maximizing gaming performance.

Battery Life

The Asus ROG Phone 9 delivers an impressive 16:41 hours of active use, showcasing excellent battery life despite its focus on power-intensive gaming. It supports 65W wired charging, reaching 100% in 46 minutes, alongside 15W wireless and 10W reverse wired charging. The iQOO 12 Pro significantly ups the ante with 120W wired charging, promising a much faster recharge time. It also offers 50W wireless charging and 10W reverse wireless. While the ROG Phone 9’s battery life is commendable, the iQOO 12 Pro’s charging speed is a major advantage for users who need to quickly top up their device.

Buying Guide

Buy the Asus ROG Phone 9 if you need a phone specifically engineered for extended gaming sessions, value a more manageable size for one-handed use, and prioritize consistent frame rates over raw benchmark scores. Buy the vivo iQOO 12 Pro if you prefer the latest chipset generation, demand the fastest possible charging speeds (120W), and prioritize a more versatile smartphone experience beyond gaming.

Frequently Asked Questions

❓ Does the Snapdragon 8 Elite in the ROG Phone 9 overheat during prolonged gaming sessions?
