Display Comparison

Both devices feature a contrast ratio of 1324:1, suggesting similar visual depth. However, the Realme 6 Pro boasts a measured peak brightness of 421 nits, which will translate to better visibility in direct sunlight compared to the Oppo A91, whose brightness is not specified. While both likely utilize IPS LCD panels, the Realme 6 Pro’s higher brightness provides a tangible advantage for outdoor use.

Camera Comparison

Both phones are listed as having Photo/Video capabilities, but detailed sensor information is missing. However, the Realme 6 Pro’s chipset includes a more advanced Image Signal Processor (ISP), enabling superior image processing and potentially better low-light performance. Without specific sensor details, it’s difficult to definitively declare a winner, but the Realme 6 Pro’s processing power gives it an edge. The absence of details suggests neither phone will compete with flagship camera systems.

Performance

The core difference lies in the chipsets. The Realme 6 Pro’s Snapdragon 720G (8nm) utilizes Kryo 465 Gold and Silver cores, clocked up to 2.3 GHz, offering a significant architectural advantage over the Oppo A91’s Helio P70 (12nm). The 8nm process of the Snapdragon 720G is more efficient, leading to better thermal management and sustained performance during demanding tasks. The Helio P70’s Cortex-A73 cores, while capable, are older and less efficient. This translates to smoother multitasking and gaming on the Realme 6 Pro.

Battery Life

Both devices have an endurance rating of 107 hours, indicating similar overall battery life despite the Oppo A91’s unspecified battery capacity. However, the Realme 6 Pro’s 30W charging significantly outperforms the Oppo A91’s 20W charging, achieving a full charge in 57 minutes versus 30 minutes for a 50% charge. This faster charging is a crucial advantage for users who prioritize convenience and minimal downtime.

Buying Guide

Buy the Oppo A91 if you prioritize a slightly more conservative design and are on a very tight budget, accepting a performance trade-off. Buy the Realme 6 Pro if you value faster performance for gaming and multitasking, quicker charging speeds, and a more modern chipset architecture, even if it means spending a bit more.
