Display Comparison
The Xiaomi Redmi Note 13 Pro 4G boasts a significantly brighter display, reaching a measured peak brightness of 1047 nits. This is a substantial advantage over what we'd expect from the Realme P3x, making it far more usable in direct sunlight. While the P3x's panel specifics are unknown, the Redmi Note 13 Pro 4G's brightness level suggests a superior viewing experience outdoors. The Redmi Note 13 Pro 4G's panel technology is likely AMOLED, offering vibrant colors and deep blacks, while the P3x's panel type is unconfirmed.
Camera Comparison
Detailed camera analysis is limited by the provided data. Both phones likely feature multi-camera setups, but the specifics are unknown. The Redmi Note 13 Pro 4G's camera system is likely to be more versatile, given Xiaomi's history of including higher-resolution sensors and advanced features in their Redmi Note series. Without sensor size or aperture information, it's difficult to definitively assess image quality, but the Redmi Note 13 Pro 4G's brand reputation suggests a more refined camera experience.
Performance
The Realme P3x's Mediatek Dimensity 6400 (6nm) represents a more modern architecture than the Redmi Note 13 Pro 4G's Helio G99 Ultra. While both CPUs feature a 2x2.2 GHz Cortex-A76 and 6x2.0 GHz Cortex-A55 configuration, the Dimensity 6400's 6nm process node offers improved power efficiency and potentially better sustained performance under load. However, the G99 Ultra is a well-optimized chip, and the real-world performance difference may not be drastic for everyday tasks. The P3x's newer architecture suggests it may handle future software updates and demanding applications more gracefully.
