Display Comparison
The Oppo Find X3 Pro boasts a brighter display, reaching a measured 774 nits, compared to an unspecified brightness for the X51 5G. While both likely utilize OLED panels, the Find X3 Pro’s higher peak brightness translates to better visibility in direct sunlight. The Find X3 Pro’s 'Infinite' contrast ratio suggests a superior panel with deeper blacks. The X51 5G’s display specs are less detailed, suggesting a more standard OLED implementation focused on efficiency rather than outright visual dominance.
Camera Comparison
Both phones are advertised as having strong camera systems, but specifics are limited. The Oppo Find X3 Pro likely benefits from the more powerful ISP within the Snapdragon 888, enabling faster image processing and potentially better low-light performance. Without detailed sensor information for the X51 5G, it’s difficult to make a direct comparison. However, the Find X3 Pro’s flagship status suggests a more advanced camera system with features like improved OIS and potentially larger sensor sizes. The inclusion of 'Photo / Video' for both indicates a focus on both still and moving image capture, but the 888’s processing capabilities give the Find X3 Pro an edge.
Performance
The core difference lies in the chipsets. The Oppo Find X3 Pro’s Snapdragon 888 (5nm) is a substantial upgrade over the vivo X51 5G’s Snapdragon 765G (7nm). The 888 features a Cortex-X1 prime core clocked at 2.84 GHz, offering significantly faster single-core performance. The 765G’s Kryo 475 Prime core at 2.4 GHz is capable, but cannot match the 888’s processing power. The 888’s Adreno 660 GPU also provides a considerable graphics boost. While the X51 5G’s 8GB of RAM is sufficient, the 888’s architecture benefits from faster memory bandwidth, further enhancing performance. The 5nm process node of the 888 also contributes to better thermal efficiency, potentially mitigating throttling during sustained workloads.
Battery Life
Both devices achieve an endurance rating of 81 hours, suggesting similar real-world battery life despite the Oppo Find X3 Pro’s more powerful chipset. This is likely due to optimizations in software and power management. However, the charging speeds are drastically different. The Oppo Find X3 Pro’s 65W wired charging can deliver a 40% charge in just 10 minutes, while the X51 5G’s 33W charging takes 30 minutes to reach 57%. The Find X3 Pro also offers 30W wireless charging and 10W reverse wireless charging, features absent on the X51 5G. This makes the Find X3 Pro significantly more convenient for users who frequently need to top up their battery.
Buying Guide
Buy the vivo X51 5G if you need a reliable 5G experience without breaking the bank, and prioritize a balanced feature set over raw power. You'll appreciate its capable camera and solid battery life for everyday tasks. Buy the Oppo Find X3 Pro if you demand top-tier performance for demanding games and applications, value incredibly fast charging, and are willing to invest in a premium smartphone experience.
