Display Comparison
While display specs aren't provided, both phones likely feature LCD panels common in their price bracket. The Realme X3, being older, may have slightly larger bezels. The Redmi Note 10 Pro (China) benefits from a newer panel manufacturing process, potentially offering improved color accuracy and viewing angles. However, without specific data on brightness and color gamut, a definitive winner is difficult to declare.
Camera Comparison
Without camera specifications, a direct comparison is limited. However, given the Redmi Note 10 Pro’s market positioning, it likely features a higher resolution main sensor. The Dimensity 1100’s integrated ISP also provides advantages in image processing, potentially leading to better dynamic range and low-light performance. The Realme X3, while capable, relies on an older ISP, potentially resulting in less refined image quality. The absence of details prevents a conclusive assessment.
Performance
The core difference lies in the chipsets. The Realme X3’s Snapdragon 855+ (7nm) was a flagship processor, boasting a Kryo 485 CPU configuration with a peak clock speed of 2.96 GHz. This provides substantial raw processing power. Conversely, the Redmi Note 10 Pro (China) utilizes the MediaTek Dimensity 1100 (6nm). While the Dimensity 1100’s Cortex-A78 cores clock higher at 2.6 GHz, the 6nm process offers superior power efficiency. This translates to less thermal throttling under sustained load, meaning the Redmi Note 10 Pro is likely to maintain higher average performance during extended gaming sessions. The Dimensity 1100’s architecture is also more modern, benefiting from improvements in AI processing and image signal processing.
Battery Life
The Redmi Note 10 Pro (China) significantly outperforms the Realme X3 in charging speed with its 67W wired charging, achieving a 100% charge in just 42 minutes. The Realme X3’s 30W charging takes 55 minutes. While battery capacity isn’t specified, the Dimensity 1100’s superior efficiency likely allows the Redmi Note 10 Pro to achieve comparable or even better battery life despite potentially having a similar or smaller battery capacity. The faster charging is a major convenience factor for users who frequently need to top up their devices.
Buying Guide
Buy the Realme X3 if you need uncompromising CPU performance for demanding tasks like emulation or consistently high frame rates in graphically intensive games, and are comfortable with managing battery life. Buy the Xiaomi Redmi Note 10 Pro (China) if you prefer a more efficient chipset, faster charging speeds, and a generally smoother, more modern user experience, even if it means sacrificing a small amount of peak CPU power.
Frequently Asked Questions
❓ Will the Snapdragon 855+ in the Realme X3 overheat during prolonged gaming sessions?
The Snapdragon 855+ is known to generate significant heat under sustained load. While the Realme X3 likely has thermal management features, expect some throttling during extended gaming, potentially leading to reduced frame rates over time. The Dimensity 1100 in the Redmi Note 10 Pro is more efficient and less prone to overheating.
❓ Does the Redmi Note 10 Pro (China) support fast charging with any standard USB-PD chargers?
Yes, the Redmi Note 10 Pro (China) supports USB Power Delivery (PD3.0) alongside its proprietary 67W charging. This means you can utilize a standard USB-PD charger for slower, but still functional, charging. However, to achieve the full 67W charging speed, you'll need the included charger or a compatible charger specifically supporting that protocol.
❓ Is the difference in CPU performance between the Snapdragon 855+ and Dimensity 1100 noticeable in everyday tasks?
For typical daily use like browsing, social media, and video streaming, the difference in CPU performance will be minimal. Both chipsets are more than capable of handling these tasks smoothly. The Snapdragon 855+’s advantage becomes apparent in more demanding applications like video editing, heavy multitasking, or graphically intensive games.
