Oppo Find X8

  • Significantly faster 80W wired charging
  • Potentially superior CPU performance with Dimensity 9400
  • 3nm chipset offers potential efficiency gains

  • Camera details are currently unknown
  • ColorOS may not appeal to all users

Samsung Galaxy S24 Ultra

  • Refined software experience with One UI
  • Versatile and well-regarded camera system
  • Strong ecosystem integration with Samsung devices

  • Slower 45W wired charging
  • Snapdragon 8 Gen 3 (4nm) may trail Dimensity 9400 in raw CPU power

Display Comparison

Both devices boast exceptional displays, but the Samsung Galaxy S24 Ultra edges ahead with a measured peak brightness of 1447 nits compared to the Oppo Find X8’s 1364 nits. This difference is noticeable in direct sunlight. While both likely employ LTPO technology for adaptive refresh rates, Samsung’s display benefits from its established calibration expertise, potentially offering more accurate color reproduction. The S24 Ultra’s slightly larger screen size and potentially narrower bezels contribute to a more immersive viewing experience.

Camera Comparison

While detailed camera analysis requires sample images, the context data highlights a key difference: the S24 Ultra explicitly mentions photo/video capabilities, suggesting a more comprehensive and refined camera experience. The larger sensor size, typically found in Samsung’s Ultra models, combined with advanced image processing algorithms, likely delivers superior image quality, especially in low-light conditions. The Oppo Find X8’s camera specs are currently unknown, but it will need to deliver exceptional performance to compete with Samsung’s established camera prowess. The absence of detail regarding the Find X8’s camera suggests it may not be a primary differentiator.

Performance

The core of this comparison lies in the chipsets. The Oppo Find X8’s Mediatek Dimensity 9400, fabricated on a 3nm process, features a unique CPU configuration with a Cortex-X925 prime core clocked at 3.63 GHz, suggesting a focus on single-core performance. This contrasts with the Snapdragon 8 Gen 3’s (4nm) Cortex-X4 prime core at 3.39 GHz. The Dimensity 9400’s architecture, with more X4 cores, could translate to superior multi-core performance. However, the Snapdragon 8 Gen 3 benefits from Qualcomm’s optimized software and extensive developer support. The S24 Ultra’s LPDDR5x RAM complements the Snapdragon, while the Find X8’s RAM specification is currently unknown, potentially impacting overall system responsiveness.

Battery Life

Battery life is remarkably close, with the Oppo Find X8 achieving 13:58 hours of active use versus the Galaxy S24 Ultra’s 13:49 hours. This suggests efficient power management on both sides. However, the charging speeds are drastically different. The Find X8’s 80W wired charging, alongside 50W wireless and 10W reverse wireless, significantly outperforms the S24 Ultra’s 45W wired, 15W wireless, and 4.5W reverse wireless. The Find X8 can likely achieve a full charge in under 30 minutes, while the S24 Ultra takes considerably longer. This makes the Find X8 the clear winner for users who prioritize rapid charging.

Buying Guide

Buy the Oppo Find X8 if you prioritize peak CPU performance, exceptionally fast 80W wired charging, and are comfortable with Oppo’s ColorOS. This phone is ideal for demanding users who frequently engage in resource-intensive tasks like video editing or heavy multitasking. Buy the Samsung Galaxy S24 Ultra if you value a refined software experience, a versatile camera system with extensive features, and the broader ecosystem benefits of the Samsung brand. It’s the better choice for users who want a polished, reliable flagship experience with strong resale value.

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 should improve thermal efficiency compared to older nodes. However, sustained peak performance will inevitably generate heat. Oppo’s thermal management system will be crucial. The Snapdragon 8 Gen 3 also benefits from improved efficiency, but real-world testing is needed to determine which chipset handles prolonged gaming better.
❓ Does the Samsung Galaxy S24 Ultra support frame rate interpolation for smoother gaming?
Samsung has historically included features like frame rate interpolation in their devices. The S24 Ultra likely supports this, potentially boosting frame rates in compatible games, but at the cost of increased power consumption and potential input lag. Users can typically toggle this feature on or off in the game launcher settings.
❓ How does the 50W wireless charging on the Oppo Find X8 compare to the 15W on the S24 Ultra in practical terms?
The 50W wireless charging on the Find X8 is significantly faster. Expect a full wireless charge in approximately 60-75 minutes, compared to over 90 minutes on the S24 Ultra. This makes the Find X8 a much more convenient option for users who frequently rely on wireless charging.
