Display Comparison

Both devices share a contrast ratio of 1269:1, suggesting similar visual pop. However, the Motorola Moto G 5G Plus boasts a measured peak brightness of 543 nits, which will translate to better visibility outdoors compared to the Oppo A91, whose brightness is not specified. While both likely utilize LCD panels given their price points, the Moto G 5G Plus’s higher brightness is a tangible advantage for outdoor usability.

Camera Comparison

Both phones offer photo and video capabilities, but detailed sensor information is lacking for the Oppo A91. The Moto G 5G Plus likely features a more sophisticated camera system, benefiting from Qualcomm’s image signal processor (ISP) integrated within the Snapdragon 765G. While the presence of a 2MP macro camera on either device is largely a marketing gimmick, the overall image quality and processing capabilities will likely favor the Moto G 5G Plus due to its more powerful chipset.

Performance

The core difference lies in the chipsets. The Motorola Moto G 5G Plus’s Qualcomm Snapdragon 765 5G (7nm) is a significant leap ahead of the Oppo A91’s MediaTek Helio P70 (12nm). The 7nm process node allows for greater transistor density and improved power efficiency, resulting in better performance and less heat generation. The Snapdragon 765G’s CPU configuration – a 1x2.3 GHz Kryo 475 Prime core, 1x2.2 GHz Kryo 475 Gold core, and 6x1.8 GHz Kryo 475 Silver cores – is architecturally more advanced than the A91’s Octa-core (4x2.1 GHz Cortex-A73 & 4x2.0 GHz Cortex-A53). This translates to faster app loading times, smoother multitasking, and a more responsive user experience on the Moto G 5G Plus.

Battery Life

Both devices share an endurance rating of 114 hours, suggesting comparable battery life under similar usage conditions. Both also support 20W wired charging, with the Oppo A91 claiming a 50% charge in 30 minutes. However, the Snapdragon 765G’s superior power efficiency in the Moto G 5G Plus could potentially offset any minor differences in battery capacity, leading to slightly longer real-world usage times.

Buying Guide

Buy the Oppo A91 if you prioritize a lower upfront cost and primarily need a phone for basic tasks like calling, texting, and light social media use. You’ll be sacrificing performance for affordability. Buy the Motorola Moto G 5G Plus if you want a smoother, more responsive experience, especially if you plan on gaming, streaming, or using 5G frequently. The Snapdragon 765G offers a significant performance boost that justifies the likely price difference.

Frequently Asked Questions

❓ Will the Helio P70 in the Oppo A91 struggle with demanding games like PUBG or Call of Duty?
Yes, the Helio P70 is likely to struggle with graphically intensive games at higher settings. You’ll likely need to lower graphics settings and frame rates to achieve a playable experience. The Snapdragon 765G in the Moto G 5G Plus offers a significantly smoother gaming experience.
❓ How much faster is the Snapdragon 765G compared to the Helio P70 in real-world usage?
The Snapdragon 765G is considerably faster, offering a noticeable improvement in app loading times, multitasking, and overall system responsiveness. Expect around a 40-60% performance increase in CPU-intensive tasks and a similar boost in GPU performance, making the Moto G 5G Plus feel much snappier.
❓ Does the Motorola Moto G 5G Plus support carrier aggregation for faster 5G speeds?
Yes, the Snapdragon 765G supports carrier aggregation, allowing it to combine multiple 5G channels for significantly faster download and upload speeds, provided your carrier supports it. This is a key advantage for maximizing your 5G experience.
❓ Is the 20W charging on either phone considered fast charging in 2024?
While 20W charging is decent, it's not considered particularly fast by 2024 standards. Many phones now offer 30W, 65W, or even faster charging speeds. However, for both devices, 20W is sufficient to top up the battery in a reasonable timeframe.
