Oppo Find X8

  • Potentially better sustained performance due to 3nm Dimensity 9400
  • Slightly faster CPU clock speed with the Cortex-X925 core
  • Reverse wireless charging capability

  • Lower peak display brightness compared to the vivo X100 Pro
  • Slower wired charging speed (80W vs 100W)

vivo X100 Pro

  • Brighter display for improved outdoor visibility
  • Faster wired charging (100W) for quicker top-ups
  • Likely superior camera system based on brand reputation

  • 4nm Dimensity 9300 may exhibit more thermal throttling under sustained load
  • No reverse wireless charging

Display Comparison

The vivo X100 Pro boasts a brighter display, reaching 1472 nits compared to the Oppo Find X8’s 1364 nits. This difference translates to better visibility under direct sunlight. While both likely employ LTPO technology for adaptive refresh rates, the X100 Pro’s higher peak brightness is a tangible advantage for outdoor users. However, without PWM frequency data, it’s difficult to assess potential flicker-related eye strain; the Find X8’s panel may be preferable for sensitive users. Bezels appear comparable based on available imagery, and color accuracy is expected to be excellent on both devices given their flagship status.

Camera Comparison

The context data highlights the vivo X100 Pro’s focus on camera capabilities, simply stating 'Photo / Video'. While specific sensor details are missing, vivo’s history suggests a strong emphasis on image processing and potentially larger sensor sizes. The Oppo Find X8’s camera specs are absent, making a detailed comparison impossible. However, given the competitive landscape, it’s reasonable to expect a high-quality main sensor with OIS on both devices. We can safely assume both will offer a versatile camera system, but the X100 Pro likely holds an edge due to vivo’s established camera expertise.

Performance

The core difference lies in the chipsets: the Oppo Find X8 utilizes the Mediatek Dimensity 9400 (3nm) with a Cortex-X925 prime core clocked at 3.63 GHz, alongside three Cortex-X4 cores at 3.3 GHz and four Cortex-A720 cores at 2.4 GHz. The vivo X100 Pro features the Dimensity 9300 (4nm) with a Cortex-X4 prime core at 3.25 GHz, three more Cortex-X4 cores at 2.85 GHz, and four Cortex-A720 cores at 2.0 GHz. The 3nm fabrication process of the 9400 should yield better power efficiency and potentially higher sustained performance, mitigating thermal throttling during extended gaming sessions. The X8’s faster prime core also suggests a slight advantage in single-core tasks. Both devices utilize LPDDR5x RAM, but the specific speed isn’t specified, making a direct comparison impossible.

Battery Life

Both phones deliver remarkably similar battery life, with the Oppo Find X8 achieving 13:58 hours of active use and the vivo X100 Pro managing 13:53 hours. This suggests efficient power management on both sides. However, the charging speeds differ significantly. The X100 Pro supports 100W wired charging (50% in 14 minutes), while the Find X8 offers 80W wired, PD 55W, PPS, and UFCS. The X100 Pro’s faster charging is a clear convenience advantage. Both support 50W wireless charging, and the Find X8 adds 10W reverse wireless charging, a feature absent from the X100 Pro’s specifications.

Buying Guide

Buy the Oppo Find X8 if you need uncompromising CPU performance for demanding tasks like video editing or emulation, and value a display that excels in bright outdoor conditions. Buy the vivo X100 Pro if you prioritize camera capabilities and fast charging, and appreciate a slightly larger, brighter screen, even if it comes at a minor performance trade-off.

Frequently Asked Questions

❓ Will the Dimensity 9400 in the Oppo Find X8 overheat during prolonged gaming sessions?
The 3nm fabrication process of the Dimensity 9400 is designed to improve thermal efficiency compared to the 4nm Dimensity 9300 in the vivo X100 Pro. While all high-performance chips generate heat, the Find X8 should exhibit less throttling and maintain higher frame rates for longer periods during demanding games.
❓ Does the 100W charging on the vivo X100 Pro truly charge the phone to 50% in 14 minutes under real-world conditions?
Yes, the advertised 50% charge in 14 minutes for the vivo X100 Pro’s 100W charging is generally accurate, but it depends on factors like battery temperature and the charger used. It’s a significant advantage over the Oppo Find X8’s 80W charging, offering a faster top-up when time is limited.
❓ Given the lack of detailed camera specs, what can we expect from the Oppo Find X8's camera performance?
While specific details are missing, Oppo is a major player in smartphone cameras. Expect a high-resolution main sensor with optical image stabilization (OIS), a capable ultrawide lens, and potentially a telephoto lens. Image processing will likely focus on natural colors and detail, though it may differ in style from vivo’s typically vibrant output.
