Display Comparison

The Sony Xperia 1 III’s display shines with a measured peak brightness of 620 nits, offering superior visibility in direct sunlight compared to the Motorola Edge 5G UW (2021), whose brightness is not specified. While the Motorola’s display specs are unknown, the Xperia 1 III’s infinite contrast ratio suggests a deeper black level and more vivid colors. The Xperia 1 III’s 21:9 aspect ratio caters to multimedia consumption and multitasking, though it may present compatibility challenges with some apps. The lack of PWM dimming information for the Motorola raises potential concerns for users sensitive to flicker, while the Xperia 1 III’s display technology is optimized for color accuracy, crucial for professional photo and video editing.

Camera Comparison

Both devices feature capable camera systems, but the Sony Xperia 1 III is geared towards professional photographers and videographers. While both are listed as having Photo/Video capabilities, the Xperia 1 III benefits from Sony’s renowned image processing algorithms and likely larger sensor sizes (specs not provided). The Motorola Edge 5G UW (2021) likely focuses on providing a versatile camera experience for everyday use, but lacks the advanced features and control offered by the Xperia 1 III. The Xperia 1 III’s video recording capabilities are a key strength, offering features like 4K HDR recording and advanced manual controls.

Performance

The Sony Xperia 1 III’s Qualcomm SM8350 Snapdragon 888 5G (5 nm) chipset significantly outperforms the Motorola Edge 5G UW (2021)’s Snapdragon 778G 5G (6 nm) in raw processing power. The Xperia 1 III’s CPU configuration, featuring a Cortex-X1 prime core clocked at 2.84 GHz, provides a noticeable advantage in demanding tasks like gaming and video rendering. However, the Snapdragon 888 is known for thermal throttling under sustained load, a potential drawback. The Motorola’s Snapdragon 778G, while less powerful, offers a more balanced thermal profile, potentially leading to more consistent performance during extended gaming sessions. The 6nm process node of the 778G contributes to better efficiency.
