Display Comparison
Both devices share an 'Infinite' (nominal) contrast ratio, suggesting standard IPS LCD panels. However, detailed display specs like resolution, peak brightness, and color gamut coverage are missing. Given the price points, expect both to offer 1080p+ resolution. The Realme 8 Pro, being positioned slightly higher, *may* benefit from a slightly better panel with improved color accuracy, but without concrete data, this remains speculative. Bezels are likely comparable, focusing on maximizing screen real estate within their respective budgets.
Camera Comparison
While both phones feature photo/video capabilities, the Realme 8 Pro likely holds an edge due to its positioning. Without specific sensor details, it’s difficult to make definitive claims. However, Realme typically prioritizes camera performance in its Pro models. The Snapdragon 720G’s ISP (Image Signal Processor) is also more capable than the 662’s, enabling better image processing and potentially superior low-light performance. The Y51a’s camera is likely adequate for casual photography, but the 8 Pro aims for a more refined experience.
Performance
The Realme 8 Pro’s Snapdragon 720G (8nm) represents a clear advantage over the vivo Y51a’s Snapdragon 662 (11nm). The 720G’s Kryo 465 Gold cores, clocked at 2.3 GHz, outperform the Y51a’s 2.0 GHz Kryo 260 Gold cores. The 8nm process node also contributes to better thermal efficiency, meaning the 8 Pro is less likely to throttle under sustained load. This translates to smoother gaming and faster app loading times for the Realme 8 Pro. While both utilize octa-core configurations, the architectural improvements in the 720G are significant.
Battery Life
Both devices boast an endurance rating of 116 hours, suggesting similar real-world battery life under moderate usage. However, the charging speeds are drastically different. The Realme 8 Pro’s 50W SuperDart charging can reach 50% in just 17 minutes and 100% in 47 minutes, a significant convenience factor. The vivo Y51a’s 18W charging takes 67 minutes to reach 70%, implying a much longer full charge time. This difference in charging speed is a major differentiator, especially for users who frequently need to top up their battery quickly.
Buying Guide
Buy the vivo Y51a if you prioritize long-term efficiency and a consistently smooth experience for basic tasks like calling, texting, and social media. It’s ideal for users who don’t heavily game or require demanding app performance. Buy the Realme 8 Pro if you value faster performance for gaming and multitasking, and if rapid charging is a must-have feature. It’s the better option for users who want a phone that can keep up with a more demanding lifestyle.
Frequently Asked Questions
❓ Does the Snapdragon 720G in the Realme 8 Pro handle demanding games like PUBG Mobile smoothly?
Yes, the Snapdragon 720G is well-equipped to handle PUBG Mobile at high settings. While it won't deliver the absolute highest frame rates, it provides a consistently smooth and enjoyable gaming experience, especially when paired with sufficient RAM. The 8nm process also helps mitigate thermal throttling during extended gaming sessions.
❓ How much of a difference will the 50W charging make in daily use on the Realme 8 Pro?
The 50W charging is a significant convenience. Being able to go from 0% to 50% in just 17 minutes, and fully charged in 47 minutes, means you can quickly top up your phone during short breaks, minimizing downtime. This is particularly useful for users who have busy schedules or frequently travel.
❓ Is the camera on the vivo Y51a sufficient for casual social media use?
Yes, the vivo Y51a’s camera is likely adequate for casual social media photography in good lighting conditions. However, it will likely struggle in low-light scenarios compared to the Realme 8 Pro, and may lack the advanced features and image processing capabilities for more serious photography.
❓ Will I notice a significant performance difference between the Snapdragon 662 and 720G in everyday tasks?
For basic tasks like browsing, social media, and messaging, the difference might not be immediately noticeable. However, when multitasking, opening demanding apps, or playing games, the Snapdragon 720G in the Realme 8 Pro will provide a noticeably smoother and more responsive experience.
