vivo Y51 (2020, September)
- More affordable price point
- Decent battery endurance
- Reliable Snapdragon 665 chipset for basic tasks
- Significantly slower charging speed
- Less powerful processor for demanding applications
- Display likely less bright than the Realme 7 Pro
Realme 7 Pro
- Much faster 65W charging
- More powerful Snapdragon 720G processor
- Brighter display for better outdoor visibility
- Higher price compared to the vivo Y51
- Battery life is similar to the Y51 despite faster charging
- Camera details are limited
Display Comparison
The Realme 7 Pro boasts a significantly brighter display, reaching a measured 585 nits, compared to an unspecified brightness for the vivo Y51. While both displays have an 'infinite' (nominal) contrast ratio, the higher peak brightness of the Realme 7 Pro translates to better visibility outdoors under direct sunlight. The panel technology is not specified for either device, but the Realme 7 Pro’s brightness advantage is a clear win for users who consume media outdoors or in brightly lit environments.
Camera Comparison
Both phones feature 'Photo / Video' capabilities, but detailed camera specifications are lacking for both. Without sensor size or aperture information, a direct comparison is difficult. However, the Realme 7 Pro’s more powerful processor likely enables more sophisticated image processing algorithms, potentially resulting in better image quality, especially in low-light conditions. The absence of details on the Y51’s camera suggests a more basic imaging experience.
Performance
The core difference lies in the chipsets: the Realme 7 Pro utilizes the Snapdragon 720G (8nm) while the vivo Y51 is equipped with the Snapdragon 665 (11nm). The 720G’s Kryo 465 cores (2x2.3 GHz Gold & 6x1.8 GHz Silver) offer a substantial performance uplift over the 665’s Kryo 260 cores (4x2.0 GHz Gold & 4x1.8 GHz Silver). The 8nm process node of the 720G also contributes to improved power efficiency and potentially less thermal throttling during sustained workloads. This means the Realme 7 Pro will handle demanding games and applications with greater ease.
Battery Life
Both devices share an endurance rating of 113 hours, suggesting similar overall battery life despite the unspecified mAh capacities. However, the Realme 7 Pro’s 65W wired charging is a massive advantage. It can reach 50% charge in just 12 minutes and a full charge in 34 minutes, drastically reducing downtime. The vivo Y51’s 18W charging is considerably slower, requiring significantly longer to replenish the battery.
Buying Guide
Buy the vivo Y51 (2020, September) if you prioritize absolute affordability and only need a phone for basic tasks like calls, messaging, and light social media use. Buy the Realme 7 Pro if you value faster performance for gaming and multitasking, and if quick charging is a must-have feature for your lifestyle. The 7 Pro is also the better option for those who plan to keep their phone for several years.
Frequently Asked Questions
❓ Is the Snapdragon 665 in the vivo Y51 sufficient for playing PUBG Mobile?
The Snapdragon 665 can run PUBG Mobile, but likely at lower graphics settings and frame rates to maintain a smooth experience. Expect some stuttering during intense firefights. The Realme 7 Pro’s Snapdragon 720G will provide a significantly smoother and more consistent gaming experience.
❓ How much faster is the 65W charging on the Realme 7 Pro compared to the 18W charging on the vivo Y51 in real-world use?
The 65W charging on the Realme 7 Pro is dramatically faster. It can charge from 0-100% in approximately 34 minutes, while the vivo Y51’s 18W charging will likely take well over 2 hours for a full charge. This difference is particularly noticeable for users who frequently need to top up their battery quickly.
❓ Does the Realme 7 Pro overheat during prolonged gaming sessions?
The Snapdragon 720G, coupled with the Realme 7 Pro’s thermal management system, generally handles prolonged gaming well. While some warming is expected, it’s unlikely to reach critical temperatures that cause significant performance throttling. The 8nm process node contributes to better thermal efficiency compared to the 11nm Snapdragon 665.
