OnePlus Ace

  • Incredibly fast 150W wired charging
  • Potentially lower price point
  • Strong CPU performance for burst tasks

  • Less efficient chipset leading to potential throttling
  • Likely inferior camera system
  • Shorter battery life compared to the X100 Ultra

vivo X100 Ultra

  • Superior Snapdragon 8 Gen 3 performance and efficiency
  • Exceptional battery life (12:55h active use)
  • Brighter display (1801 nits)

  • Slower wired charging (80W) compared to the Ace
  • Higher price point
  • May lack the Ace's aggressive gaming focus

Display Comparison

The vivo X100 Ultra boasts a significantly brighter display, reaching a measured 1801 nits, compared to an unspecified peak brightness for the OnePlus Ace. This translates to superior visibility under direct sunlight. While the Ace’s panel technology isn’t detailed, the X100 Ultra likely utilizes LTPO technology, enabling adaptive refresh rates for improved power efficiency. The X100 Ultra’s brightness advantage is crucial for outdoor users and content creators.

Camera Comparison

Without detailed camera specifications for the OnePlus Ace, a direct comparison is limited. However, the vivo X100 Ultra is expected to feature a more advanced camera system, leveraging the Snapdragon 8 Gen 3’s superior image signal processor (ISP). The X100 Ultra’s focus on image processing and potentially larger sensor sizes (not specified) will likely result in better low-light performance and dynamic range. The Ace’s camera is likely competent, but the X100 Ultra aims for a higher tier of photographic quality.

Performance

The Snapdragon 8 Gen 3 in the vivo X100 Ultra, fabricated on a 4nm process, represents a substantial leap in performance and efficiency over the 5nm Mediatek Dimensity 8100 Max found in the OnePlus Ace. The Snapdragon’s Cortex-X4 prime core, clocked at 3.3 GHz, offers a significant single-core performance advantage. Furthermore, the Snapdragon 8 Gen 3’s improved thermal management, due to the more efficient 4nm node, will result in less throttling during extended gaming sessions. The Ace’s Dimensity 8100 Max, while capable, will struggle to maintain peak performance under sustained load.

Battery Life

The vivo X100 Ultra’s 12:55h active use score demonstrates exceptional battery life, a direct result of the Snapdragon 8 Gen 3’s efficiency. While the OnePlus Ace offers incredibly fast 150W wired charging (50% in 5 minutes), the X100 Ultra’s 80W wired charging, coupled with 30W wireless and reverse charging capabilities, provides a more versatile charging ecosystem. The Ace prioritizes speed, while the X100 Ultra prioritizes longevity and convenience.

Buying Guide

Buy the OnePlus Ace if you need blazing-fast 150W wired charging and prioritize raw CPU performance for tasks like video editing or demanding mobile games, and are comfortable with potentially more thermal throttling. Buy the vivo X100 Ultra if you prefer a more balanced experience with exceptional battery life (12:55h active use), a brighter display (1801 nits), and the superior processing power of the Snapdragon 8 Gen 3 for sustained performance and future-proofing.

Frequently Asked Questions

❓ Does the Dimensity 8100 Max in the OnePlus Ace get hot during prolonged gaming sessions?
The Mediatek Dimensity 8100 Max, while powerful, is fabricated on a 5nm process which is less thermally efficient than the 4nm Snapdragon 8 Gen 3. Expect some degree of thermal throttling during extended gaming, potentially leading to reduced frame rates over time. The X100 Ultra’s Snapdragon 8 Gen 3 is better equipped to handle sustained workloads.
❓ How does the 80W charging on the vivo X100 Ultra compare to the 150W charging on the OnePlus Ace in real-world use?
While 150W is faster on paper, the difference in practical terms isn't as dramatic as the numbers suggest. The OnePlus Ace can reach 50% charge in 5 minutes, but the X100 Ultra’s 80W charging is still very fast and offers the added benefits of wireless and reverse charging options, providing greater flexibility.
❓ Is the Snapdragon 8 Gen 3 in the vivo X100 Ultra significantly more power-efficient than the Dimensity 8100 Max?
Yes, the Snapdragon 8 Gen 3’s 4nm process node is demonstrably more power-efficient than the Dimensity 8100 Max’s 5nm node. This translates directly into longer battery life, as evidenced by the X100 Ultra’s 12:55h active use score. The improved efficiency also contributes to better thermal management.
