2. Key Insights

  • Xiaomi 12X:
    • Strengths: Superior display with 120Hz refresh and higher brightness, more powerful Snapdragon 870 chipset, better wide-angle and macro cameras, 8K video capability, optical image stabilization (OIS), enhanced audio with Dolby Atmos, and robust screen protection with Gorilla Glass Victus.
    • Competitive Advantages: More fluid UI, better performance, better image capture quality, top-notch audio, and more durable build.
    • Trade-offs: Older Android OS out of the box and not tested by DXOMark.
  • Oppo Reno8:
    • Strengths: Faster 80W charging, newer Android OS, and potentially better selfie camera in low light due to a larger sensor.
    • Competitive Advantages: Quicker charging and an updated software experience.
    • Trade-offs: Lower display refresh rate and brightness, weaker chipset, and less versatile camera system, and no screen protection mentioned.

3. User Profiles and Recommendations

  • Xiaomi 12X:
    • Best Suited For: Gamers, media enthusiasts, photography enthusiasts, and power users who prioritize smooth performance, visual quality, and robust build.
    • Use Cases: High-performance gaming, extensive media consumption, content creation and photography, and users who need a reliable phone for outdoor use and don't mind installing a custom ROM.
  • Oppo Reno8:
    • Best Suited For: Users who prioritize fast charging, the latest Android experience, and good selfie quality in low light.
    • Use Cases: Everyday users who need a reliable phone that charges quickly, good for video calls, and basic photography, who value the latest software.

4. Buying Decision Framework

Here are three crucial questions to help you decide:

  1. Do you prioritize gaming and smooth overall performance? If yes, the Xiaomi 12X is the better choice due to its Snapdragon 870 chipset and 120Hz display.
  2. Do you need the absolute fastest charging speed and the latest software experience? If so, the Oppo Reno8's 80W charging and newer Android version will serve you best.
  3. How important is outdoor screen visibility and screen durability? If very important, the Xiaomi 12X with 1100 nits brightness and Gorilla Glass Victus is the clear winner.

Scenario-Based Recommendations:

  • The Gamer: Choose the Xiaomi 12X for its superior performance and smoother display.
  • The Everyday User: If you mostly browse social media and watch videos, the Oppo Reno8 will satisfy, but the Xiaomi 12X has better performance.
  • The Photographer: Choose the Xiaomi 12X, with better quality wide and macro lens, with optical image stabilization.
  • The Tech Enthusiast: Go for the Xiaomi 12X if you want cutting-edge features and top-tier performance, and Oppo Reno8 if you prefer a smoother, less buggy software experience.

My Choice

If I had to choose between these two, I'd pick the Xiaomi 12X. Here's why:

As a tech journalist and smartphone enthusiast, I value performance and user experience above all. The 120Hz display with its high peak brightness provides a significantly more enjoyable visual experience than the 90Hz and lower brightness on the Oppo Reno8. The Snapdragon 870 is a reliable, powerful chip that handles everything I throw at it, and the inclusion of OIS for video is a great addition. While I appreciate fast charging, the benefits of a better screen and smoother performance far outweigh the convenience of the Oppo's 80W charging. The build quality with Gorilla Glass Victus also adds a layer of durability, which I consider crucial. Plus the Dolby Atmos speakers with Hi-Res audio are a great addition for media consumption, and for anyone who appreciates good audio.

The Xiaomi 12X may have an older OS out of the box, but the benefits of its display, performance, and camera capabilities make it the winner in this case, in my opinion.
