Why does a Graphics Card help in Machine Learning?

The graphics card, also known as Graphics Processing Unit (GPU), is responsible for calculating images in a computer, which can then be displayed on a monitor. It represents the interface between the processor's calculations and the monitor. However, the development of graphics cards is now so far advanced that, in addition to this function, they can also support and relieve the CPU during calculations. The computer's processor calculates what data a certain program wants to display on the screen and outputs it as so-called image data. This, mostly numerical, data is then converted by the GPU so that it can be displayed on a monitor or other device. Many laptops and computers contain graphics cards that are already mounted on the circuit board, i.e. the mainboard.
