Display Comparison
The OnePlus 9 Pro boasts a measured peak brightness of 859 nits, suggesting a more visible display in direct sunlight compared to the Oppo Find X3 (brightness data unavailable). While both likely utilize high-refresh-rate AMOLED panels, the OnePlus 9 Pro’s display technology is more widely documented for its color accuracy and LTPO implementation, potentially leading to more dynamic refresh rate adjustments for improved battery efficiency. Bezels are expected to be comparable, given both phones target the flagship segment.
Camera Comparison
Both phones are equipped for strong photo and video capabilities, but details beyond that are limited. The OnePlus 9 Pro’s camera system, developed in partnership with Hasselblad, likely emphasizes color science and dynamic range. Sensor size and lens apertures are critical factors not provided, but the OnePlus 9 Pro’s marketing focused heavily on its camera prowess. The Oppo Find X3 likely prioritizes a balanced camera experience, but without specific sensor details, a definitive comparison is difficult. We can safely assume both phones offer capable main sensors and ultrawide lenses, but the OnePlus 9 Pro likely has the edge in overall image quality and versatility.
Performance
The core difference lies in the chipsets. The OnePlus 9 Pro’s Snapdragon 888 (5nm) offers a theoretical performance advantage over the Oppo Find X3’s Snapdragon 870 (7nm). The 888’s Cortex-X1 prime core provides a significant boost in single-core performance, beneficial for demanding applications. However, the 888 is known to run hotter, potentially leading to thermal throttling during sustained loads. The 870, while less powerful on paper, is renowned for its efficiency and sustained performance. Both phones feature ample RAM, likely LPDDR5, minimizing performance bottlenecks. The OnePlus 9 Pro’s GPU will also provide a noticeable edge in graphically intensive tasks.
Battery Life
Both devices share an endurance rating of 86 hours, suggesting comparable real-world battery life despite potential differences in battery capacity (data unavailable for the Find X3). However, charging speeds diverge significantly. The OnePlus 9 Pro’s 65W wired charging achieves a full charge in just 29 minutes, while the Oppo Find X3 takes 80 minutes for a full wireless charge and 10 minutes for a 40% wired charge. The OnePlus 9 Pro also offers 50W wireless charging, significantly faster than the Find X3’s 30W. This makes the OnePlus 9 Pro the clear winner for users who prioritize rapid replenishment.
Buying Guide
Buy the Oppo Find X3 if you prioritize a slightly more efficient chipset and are sensitive to price. The Snapdragon 870 provides excellent performance for everyday tasks and gaming without the potential for aggressive throttling seen in some Snapdragon 888 implementations. Buy the OnePlus 9 Pro if you demand the absolute highest performance potential, value faster charging speeds, and appreciate a more refined software experience, even if it comes with a slight risk of thermal limitations.
