Oppo A9 (2020) 4GB 128GB

Processor

This Oppo is powered by a Qualcomm Snapdragon 665 64-bit chip with a 2,0 Ghz Quad-Core + 1,8 Ghz Quad-Core core distribution. One of the main advantages of an octa-core phone is that it can provide better performance than a chip with fewer cores. With eight processor cores, an octa-core chip can handle several tasks at the same time. This enables smooth multi-tasking, such as switching between multiple apps, streaming videos, and performing intensive tasks without lag. Moreover, modern octa-core chips are often designed with energy efficiency in mind. They can dynamically switch between high performance and power efficient cores depending on the task required to optimize the phone's battery life.

As apps and operating systems become increasingly demanding, an octa-core chip offers a good degree of future-proof because it is able to cope with the growing demand for computing power.

This combination therefore gives a maximum power of an octa-core processor with 4096 MB RAM. With a thickness of 9.1 millimeters, the device is not too thick. This phone weighs 195 grams.

Camera

This can be useful if you want to zoom in on an image or crop it without losing too much detail, or if you want to print the photo at a large size and still have it look good. In general, a higher megapixel count in a camera means that it is capable of capturing more detail, which can be especially useful in certain situations such as when you need to take a close-up photo or when you are shooting in low light. You can also use the selfie camera in the drop-shaped notch of 16,18 megapixel for video calling, for example.
