Display Comparison
The Poco X6 Pro immediately distinguishes itself with a measured peak brightness of 1148 nits, offering superior visibility in direct sunlight compared to the likely lower brightness of the Realme P3x (spec not provided). While both likely utilize AMOLED panels, the X6 Pro’s higher brightness suggests a more advanced panel generation. The Realme P3x’s display specifications are currently unknown, making a detailed comparison of color accuracy and refresh rate impossible, but the X6 Pro’s brightness advantage is a clear win for outdoor usability.
Camera Comparison
Detailed camera analysis is hampered by limited information on the Realme P3x. However, the Poco X6 Pro’s camera system is likely to be more capable due to the chipset’s superior image signal processor (ISP). While megapixel counts aren’t provided for either device, the Dimensity 8300 Ultra’s ISP supports advanced features like 4K HDR video recording and improved low-light performance. The P3x will likely offer a competent camera for everyday use, but the X6 Pro is expected to deliver higher-quality photos and videos, particularly in challenging conditions.
Performance
The core difference lies in the chipsets. The Poco X6 Pro’s Mediatek Dimensity 8300 Ultra (4nm) is a substantial upgrade over the Realme P3x’s Dimensity 6400 (6nm). The 8300 Ultra’s CPU configuration – 1x3.35 GHz Cortex-A715, 3x3.20 GHz Cortex-A715, and 4x2.20 GHz Cortex-A510 – is both faster and more efficient than the P3x’s 2x2.5 GHz Cortex-A76 & 6x2.0 GHz Cortex-A55. The 4nm process node of the 8300 Ultra further enhances efficiency, leading to less thermal throttling during sustained workloads. This translates to smoother gaming, faster app loading times, and an overall more responsive experience on the Poco X6 Pro.
Battery Life
The Poco X6 Pro demonstrates a clear advantage in charging speed with its 67W wired charging, capable of a full charge in 45 minutes, and support for QC2.0 and PD3.0 standards. The Realme P3x’s 45W charging is respectable, but slower. The Poco X6 Pro also boasts an impressive 11:46h active use battery score, suggesting excellent battery life despite the power-hungry chipset. While the P3x’s battery capacity is unknown, the X6 Pro’s combination of efficient chipset and fast charging provides a more convenient and reliable experience.
Buying Guide
Buy the Realme P3x if you prioritize a more budget-friendly option and value a balanced feature set without demanding top-tier gaming performance. Buy the Xiaomi Poco X6 Pro if you're a power user, mobile gamer, or someone who frequently performs demanding tasks and appreciates faster charging speeds and a brighter display.
Frequently Asked Questions
❓ Will the Poco X6 Pro’s Dimensity 8300 Ultra get hot during extended gaming sessions?
While the Dimensity 8300 Ultra is a powerful chip, the 4nm process node and Xiaomi’s thermal management solutions should mitigate overheating. However, some thermal throttling is possible during prolonged, graphically intensive gaming. Expect warm temperatures, but not to the point of significant performance degradation.
❓ Does the Realme P3x support 5G connectivity?
Given the Dimensity 6400 chipset, the Realme P3x is expected to support 5G connectivity. However, the specific 5G bands supported will vary depending on the region. Check the product specifications for your region to confirm compatibility with your carrier.
❓ Is the 45W charging on the Realme P3x sufficient for daily use?
45W charging is a respectable speed and should adequately recharge the device overnight. However, it’s noticeably slower than the 67W charging on the Poco X6 Pro, meaning you’ll need to spend more time plugged in to top up the battery.
