Oppo Reno15 Pro Max

  • Faster processor with Dimensity 9400 (3nm)
  • Industry-leading 120W wired charging
  • Potentially superior gaming performance

  • Battery life likely shorter than X100 Pro
  • Camera specs currently unknown

vivo X100 Pro

  • Excellent battery life (13:53h active use)
  • Brighter display (1472 nits)
  • Potentially superior camera system

  • Slightly slower processor (Dimensity 9300, 4nm)
  • Slower wired charging (100W)

Display Comparison

The vivo X100 Pro boasts a significantly brighter display, reaching a measured 1472 nits, which translates to superior visibility in direct sunlight. While the Reno15 Pro Max’s display specs are not provided, it’s likely to be slightly dimmer. Both devices likely employ LTPO technology for adaptive refresh rates, conserving battery life. Without further data on the Reno15 Pro Max’s panel, it’s difficult to assess color accuracy or bezel size, but the X100 Pro’s brightness advantage is a clear win for outdoor usability.

Camera Comparison

The context data highlights 'Photo / Video' capabilities for the vivo X100 Pro, but lacks specific sensor details. Given vivo’s history, it’s reasonable to expect a high-resolution main sensor with advanced OIS. The Reno15 Pro Max’s camera specs are also absent, making a direct comparison impossible. However, the X100 Pro’s brand reputation suggests a stronger emphasis on image processing and overall camera quality. Without sensor size and aperture information, it’s difficult to assess low-light performance, but the X100 Pro is likely to excel in this area.

Performance

The core difference lies in the chipsets. The Oppo Reno15 Pro Max utilizes the Mediatek Dimensity 9400, fabricated on a more efficient 3nm process, featuring a Cortex-X925 prime core clocked at 3.63 GHz. This contrasts with the vivo X100 Pro’s Dimensity 9300, built on a 4nm node, and topped by a Cortex-X4 prime core at 3.25 GHz. The 3nm process and higher clock speed of the X925 suggest a performance advantage for the Reno15 Pro Max in CPU-intensive tasks. However, the X100 Pro’s CPU configuration, with three Cortex-X4 cores, may offer sustained multi-core performance. Both devices likely feature LPDDR5x RAM, but thermal management will be crucial in determining real-world performance consistency.

Battery Life

The vivo X100 Pro demonstrates a clear advantage in battery endurance, achieving 13 hours and 53 minutes of active use. The Reno15 Pro Max’s battery capacity is unknown, but its 120W wired charging (along with 50W wireless) significantly surpasses the X100 Pro’s 100W wired and 50W wireless charging. The Reno15 Pro Max can reach 50% charge in a shorter time, but the X100 Pro’s longer battery life may negate the need for frequent top-ups. Both support reverse wired charging, adding to their versatility.

Buying Guide

Buy the Oppo Reno15 Pro Max if you need uncompromising processing power for demanding games and applications, and value the convenience of the fastest wired charging available. Buy the vivo X100 Pro if you prioritize all-day battery life, a refined camera experience, and a more balanced overall package, even if it means sacrificing some raw speed.

Frequently Asked Questions

❓ Does the Dimensity 9400 in the Reno15 Pro Max generate excessive heat during prolonged gaming sessions?
The 3nm process of the Dimensity 9400 should improve thermal efficiency compared to the 4nm Dimensity 9300 in the X100 Pro. However, sustained peak performance will inevitably generate heat. Oppo’s thermal management system will be critical in preventing throttling and maintaining consistent frame rates during extended gaming.
❓ How does the 120W charging of the Reno15 Pro Max compare to the 100W charging of the X100 Pro in real-world scenarios?
While both offer incredibly fast charging, the Reno15 Pro Max’s 120W charging will likely provide a faster initial charge. The X100 Pro claims 50% charge in 14 minutes; the Reno15 Pro Max should beat that. However, the difference becomes less significant as the battery approaches full capacity, and the X100 Pro’s larger battery capacity provides a longer overall runtime.
❓ Is the difference between the Cortex-X925 and Cortex-X4 cores in these phones noticeable for everyday tasks?
For typical everyday tasks like browsing, social media, and video playback, the difference between the Cortex-X925 and Cortex-X4 cores will be minimal. Both processors are exceptionally powerful and will handle these tasks with ease. The performance gap will become more apparent in demanding applications like video editing, 3D rendering, and graphically intensive games.
