Oppo Reno15

  • Faster wired charging (80W)
  • Sleek and stylish design
  • Potentially more versatile camera system

  • May experience more thermal throttling under heavy load
  • Less focused on gaming-specific features

Asus ROG Phone 6 Diablo Immortal Edition

  • Superior gaming performance with Snapdragon 8+ Gen 1
  • Advanced cooling system for sustained performance
  • Gaming-centric features (likely including triggers and high refresh rate display)

  • Slower wired charging (65W)
  • Potentially bulkier design

Display Comparison

While both devices utilize 4nm chipsets, display details are missing. Assuming the ROG Phone 6 follows typical ROG trends, it likely features a higher refresh rate (144Hz or higher) AMOLED panel with excellent color accuracy and brightness. The Reno15, positioned as a more mainstream flagship, may opt for a 120Hz AMOLED. The ROG Phone 6’s panel is likely LTPO, offering variable refresh rate for improved efficiency. Bezels are expected to be minimal on both, but the ROG Phone 6 may have slightly larger bezels to accommodate gaming-focused features.

Camera Comparison

Camera specifications are not fully detailed. However, given the ROG Phone 6’s gaming focus, its camera system is likely optimized for quick snapshots and social media sharing rather than professional-grade photography. The Reno15, positioned as a more versatile flagship, likely features a more sophisticated camera setup with a larger main sensor and potentially optical image stabilization (OIS). The Reno15’s image processing is likely tuned for more vibrant and detailed photos, while the ROG Phone 6 may prioritize speed and convenience.

Performance

The Asus ROG Phone 6 Diablo Immortal Edition leverages the Qualcomm Snapdragon 8+ Gen 1, featuring a Cortex-X2 prime core clocked at 3.19 GHz. This architecture prioritizes peak performance, crucial for demanding games. The Oppo Reno15, powered by the Mediatek Dimensity 8450 with a 3.25 GHz octa-core CPU, offers strong performance but may exhibit slightly more thermal throttling under sustained load. The Snapdragon 8+ Gen 1’s improved efficiency on a 4nm node gives the ROG Phone 6 an edge in maintaining consistent performance during extended gaming sessions. Both likely utilize LPDDR5X RAM, but the ROG Phone 6’s advanced cooling system is the key differentiator for sustained performance.

Battery Life

The ROG Phone 6 offers 65W wired charging with support for PD3.0 and QC5, while the Reno15 boasts an impressive 80W wired charging, alongside 13.5W PD, 44W UFCS, and 55W PPS. This suggests the Reno15 will achieve a faster 0-100% charge time. However, the ROG Phone 6’s larger battery capacity (likely 5000mAh or greater) combined with the Snapdragon 8+ Gen 1’s efficiency could translate to longer real-world battery life, especially during gaming. Both offer 10W reverse wired charging, a useful feature for topping up accessories.

Buying Guide

Buy the Oppo Reno15 if you need a stylish, well-rounded smartphone with fast charging and a capable processor for everyday use and light gaming. It’s ideal for users who value aesthetics and a more balanced feature set. Buy the Asus ROG Phone 6 Diablo Immortal Edition if you prioritize uncompromising gaming performance, extended gaming sessions, and a feature-rich ecosystem designed specifically for mobile esports. This is the phone for those who live and breathe mobile gaming.

Frequently Asked Questions

❓ Will the Dimensity 8450 in the Oppo Reno15 struggle with graphically demanding games like Genshin Impact?
The Dimensity 8450 is a capable processor, but it may experience some throttling during extended Genshin Impact sessions. While playable, you might need to lower graphics settings to maintain a consistent frame rate. The ROG Phone 6’s Snapdragon 8+ Gen 1 and superior cooling are better suited for sustained high-performance gaming.
❓ How much of a difference will the cooling system make on the Asus ROG Phone 6 Diablo Immortal Edition during long gaming sessions?
The ROG Phone 6’s advanced cooling system (likely a combination of vapor chamber, graphite sheets, and potentially external fan accessories) is crucial. It prevents the Snapdragon 8+ Gen 1 from throttling as quickly, allowing it to maintain peak performance for significantly longer periods compared to the Reno15. This translates to smoother frame rates and a more consistent gaming experience.
❓ Does the Oppo Reno15's 80W charging significantly outperform the ROG Phone 6's 65W charging in real-world use?
Yes, the 80W charging on the Reno15 will likely result in a noticeably faster 0-100% charge time. While 65W is still fast, the 15W difference is substantial. However, consider that the ROG Phone 6 may have a larger battery capacity, partially offsetting this advantage.
