vivo S15 Pro

  • More efficient 5nm Dimensity 8100 chipset
  • Potentially better thermal management
  • Faster charging speed (70% in 18 mins)

  • Display specifications largely unknown
  • Camera details are lacking

Realme GT Neo 3T

  • Proven Snapdragon 870 performance
  • Measured 803 nits peak brightness
  • Competitive price point

  • Older 7nm process node
  • Potentially more throttling under sustained load

Display Comparison

The Realme GT Neo 3T boasts a measured peak brightness of 803 nits, a respectable figure for outdoor visibility. While the vivo S15 Pro’s display specifications are not provided, it’s reasonable to expect similar or slightly better brightness given its positioning. Both phones feature an 'Infinite' contrast ratio, a marketing term that doesn’t provide concrete information. Without knowing the panel technology (AMOLED vs LCD) or refresh rate of the S15 Pro, it’s difficult to definitively declare a winner, but the GT Neo 3T’s measured brightness gives it a slight edge based on available data.

Camera Comparison

Both devices are listed as having 'Photo / Video' capabilities, offering minimal insight. Without sensor size, aperture, or OIS details, a meaningful camera comparison is impossible. It’s likely both phones feature a multi-camera setup, but the quality will depend heavily on the primary sensor and image processing algorithms. The presence of a 2MP macro camera on either device is unlikely to significantly impact image quality and should be considered a secondary feature.

Performance

The core difference lies in the chipsets. The vivo S15 Pro’s MediaTek Dimensity 8100 (5nm) utilizes a more modern architecture than the Realme GT Neo 3T’s Qualcomm Snapdragon 870 (7nm). The 5nm process node translates to improved power efficiency and potentially better thermal performance, reducing the likelihood of throttling during extended gaming sessions. While the Snapdragon 870’s Kryo 585 prime core clocks higher at 3.2 GHz compared to the Dimensity 8100’s 2.85 GHz Cortex-A78, the architectural improvements and node advantage of the Dimensity chip generally result in superior overall performance. The lack of LPDDR5x RAM specification for either phone makes a direct RAM speed comparison impossible, but both are likely to utilize fast RAM configurations.

Battery Life

Both the vivo S15 Pro and Realme GT Neo 3T support 80W wired charging, with the S15 Pro claiming a 70% charge in 18 minutes. Both phones share an endurance rating of 118 hours, suggesting similar real-world battery life despite potentially different battery capacities (not specified). The fast charging speeds are the key takeaway here, allowing for quick top-ups and minimizing downtime. The efficiency of the Dimensity 8100 in the S15 Pro *could* translate to slightly better battery life under heavy load, but the identical endurance rating suggests a similar overall experience.

Buying Guide

Buy the vivo S15 Pro if you need a phone capable of handling demanding applications, multitasking, and future software updates with ease. Its superior chipset and potentially better thermal management make it ideal for power users. Buy the Realme GT Neo 3T if you prioritize value and a proven, reliable chipset for gaming and everyday tasks, and are comfortable with a slightly older processor generation.

Frequently Asked Questions

❓ Will the Snapdragon 870 in the Realme GT Neo 3T struggle with demanding games like Genshin Impact?
The Snapdragon 870 is still a capable chipset, and can run Genshin Impact, but you may need to lower graphics settings for a consistently smooth experience. The Dimensity 8100 in the vivo S15 Pro will handle these games with higher settings and less thermal throttling.
❓ How does the 80W charging on both phones compare in real-world usage?
Both phones offer incredibly fast charging. While the vivo S15 Pro claims 70% in 18 minutes, both will likely fully charge from 0-100% in under 40 minutes. The key benefit is minimizing downtime, allowing you to quickly top up your battery when needed.
❓ Is the difference between the 5nm and 7nm process nodes significant for everyday use?
For basic tasks like browsing and social media, the difference is minimal. However, during intensive tasks like gaming or video editing, the 5nm Dimensity 8100 in the vivo S15 Pro will be more power-efficient, resulting in cooler operation and potentially longer sustained performance.
❓ Does either phone have expandable storage via microSD card?
Neither device's specifications mention microSD card support. It's highly unlikely either phone offers expandable storage, so consider your storage needs carefully before purchasing.
