An Android tablet with a quad core processor is often able to do computations in parallel more effectively than a tablet with a dual core or single core processor, resulting in improved performance. This improved performance may often be more noticeable when using multiple apps, or when using apps or games that have been optimized to work efficiently on multi-core devices.Continue Reading
The Android operating system is designed to take advantage of a feature called multithreading, so a quad-core Android tablet often has smoother user interface animations than a dual or single core device. For example, a single core Android tablet might cause a user interface to animate jerkily whilst sending an email, whereas a properly designed dual or quad core app could do it smoothly by spreading the tasks out across different processor cores.
Modern Android tablets often use their multi-core processor architectures to improve battery life, according to AndroidAuthority.com. The Android operating system is able to do this by turning processor cores off when the device does not need to use them, such as when the tablet is only running a few apps that do not require much processing time. In ordinary use, Android tries to choose the best combination of cores for the task at hand, in order to balance battery life and performance.
Eight core processors are already on the market, in devices such as the Samsung Galaxy Note 10.1. These devices follow the same principle as older quad-core tablets by turning idle cores off to save power. However, it is important to note that more cores do not necessarily translate to better performance or battery life. When searching for a new tablet it is worth referring to processor comparisons, such as the Android CPUMark Ratings on AndroidBenchmark.net.Learn more about Mobile
