Oppo Find X2

  • Significantly brighter display for outdoor visibility
  • Ultra-fast 65W wired charging
  • Potentially superior camera image quality (based on brand positioning)

  • Slightly less powerful processor (Snapdragon 865 vs 865+)
  • Likely shorter battery life compared to ROG Phone 3

Asus ROG Phone 3

  • More powerful Snapdragon 865+ processor for gaming
  • Excellent battery endurance (120h rating)
  • Optimized thermal management for sustained performance

  • Dimmer display compared to Oppo Find X2
  • Slower 30W wired charging

Display Comparison

The Oppo Find X2 boasts a significant advantage in display brightness, reaching a measured 850 nits compared to the ROG Phone 3’s 719 nits. This translates to superior visibility under direct sunlight. While both utilize AMOLED technology, the Find X2’s higher peak brightness and likely superior color calibration (though not specified) make it the better choice for media consumption. The ROG Phone 3, however, offers an 'infinite' contrast ratio, typical of AMOLED panels, and a 120Hz refresh rate (not specified for the Find X2, but likely 60Hz), contributing to smoother animations, particularly beneficial in gaming. The lack of LTPO technology in either device means refresh rate scaling isn't as efficient as newer panels.

Camera Comparison

Both devices feature capable camera systems, but the context data provides limited detail for a thorough comparison. Both are described as offering 'Photo / Video' capabilities. Without sensor size or megapixel counts, it’s difficult to definitively assess image quality. However, given Asus’s gaming focus, the ROG Phone 3’s camera is likely tuned for speed and convenience rather than photographic excellence. The Find X2, positioned as a flagship, likely prioritizes image quality and offers more advanced camera features, though specifics are unavailable. The absence of detail regarding OIS or lens apertures further hinders a meaningful comparison.

Performance

Both phones are powered by the Qualcomm Snapdragon 865 5G chipset, but the ROG Phone 3 features the slightly enhanced Snapdragon 865+ variant. This 'plus' version boasts a higher peak CPU clock speed – 3.10 GHz on the ROG Phone 3 versus 2.84 GHz on the Find X2 – resulting in a marginal performance boost in CPU-intensive tasks. Both share the same CPU core configuration (1x Cortex-A77 at higher clock, 3x Cortex-A77, 4x Cortex-A55). The ROG Phone 3’s larger vapor chamber cooling system and optimized software further contribute to sustained performance under heavy load, mitigating thermal throttling during extended gaming sessions. Both devices utilize 12GB of RAM, ensuring smooth multitasking.

Battery Life

The Asus ROG Phone 3 claims an impressive 120-hour endurance rating, suggesting excellent battery life. While the Find X2’s battery capacity isn’t specified, the ROG Phone 3’s endurance rating, combined with its 30W charging (versus the Find X2’s significantly faster 65W), indicates a focus on longevity. The Find X2’s 65W wired charging can fully charge the device in just 38 minutes, a substantial advantage over the ROG Phone 3’s slower charging speed. The ROG Phone 3 also offers 10W reverse wired charging, a feature absent on the Find X2.

Buying Guide

Buy the Oppo Find X2 if you need a beautifully designed phone with a vibrant, bright display for everyday use, content consumption, and photography. It’s ideal for users who value a balanced experience and rapid charging. Buy the Asus ROG Phone 3 if you prioritize sustained gaming performance, long battery life, and features tailored to mobile esports, even if it means sacrificing some display brightness and a more subdued aesthetic.

Frequently Asked Questions

❓ Does the Snapdragon 865+ in the ROG Phone 3 offer a noticeable gaming advantage over the Snapdragon 865 in the Find X2?
While the performance difference isn't massive in synthetic benchmarks, the Snapdragon 865+’s higher clock speed and the ROG Phone 3’s superior cooling system translate to more sustained frame rates and less thermal throttling during extended gaming sessions. This is particularly noticeable in demanding titles like PUBG or Genshin Impact.
❓ How much faster is the Oppo Find X2's 65W charging in real-world use compared to the ROG Phone 3's 30W charging?
The Oppo Find X2 can charge from 0 to 100% in approximately 38 minutes. The ROG Phone 3, with its 30W charging, will take considerably longer – likely over an hour and a half – to achieve a full charge. This makes the Find X2 ideal for users who need a quick power boost.
❓ Is the lack of a high refresh rate display (like 120Hz) on the Oppo Find X2 a significant drawback?
For everyday use, the absence of a high refresh rate is unlikely to be a major issue. However, gamers and users who frequently scroll through content will appreciate the smoother experience offered by the ROG Phone 3’s 120Hz display.
