What role does the processor play when choosing a tablet
If you do not go into details, then the best processors work on the architecture A7, A9, A15 and their performance depends directly on the number of nuclei and the frequency of each of them.
Typically, the most budget tablets are equipped with a single -core processor with a frequency of 0.6 to 1 GHz. On such devices you can watch movies, listen to music, but they will not be able to boast. Double -core processors are more productive and pull the majority of games, almost never giving lags. Quad -core, almost never slow down anywhere, but are also much more expensive than the rest.
Other points: RAM memory, main memory and battery. The more RAM installed, the more applications you can open at the same time; The more memory, the more information you can store; The more capacious battery, the greater the battery life will be.
