7nm and 6nm generally refer to the chip process process, that is, the size of the transistor gate circuit that deals with the surface of the CPU and GPU. Generally there are 14nm, 7nm, 5nm, no 6nm chip process process, in general, the process process is advanced, the smaller the size of the transistor, then the same size of the chip surface can accommodate the number of transistors, the stronger the performance! So 5nm performance is definitely stronger than 7nm
In fact, for different devices, the required chip process is different, such as the mobile phone industry and more sophisticated than the mobile phone requires processing speed of the instrument above, the processor itself can not be too large, if the general mobile phone motherboard and related motherboard CPU slot is not allowed, if you want to make the CPU bigger, This also means that the motherboard design of the entire mobile phone will change, but also the change of the entire industry, if the CPU occupies a large space, other components will inevitably be affected, such as memory, storage hard disk, camera components, batteries, graphics chips and so on need to be location bearing!
