Living on the motherboard, a PC’s chipset controls the communication between the CPU, RAM, memory and other peripherals. The chipset determines how many high-speed components or USB devices the motherboard can support. Chipsets are generally composed of one to four chips and feature controllers for commonly used peripherals, such as a keyboard, mouse or monitor.
PC chipsets are designed by Intel and AMD but are found on motherboards of a variety of third-party vendors, such as MSI, Asus and ASRock. Different chipsets support different CPUs, so when buying a CPU, you have to consider that your processor will only work with motherboards that use a specific type (and CPU socket).
It is important to note that while a chipset may have some functionality (such as support for up to 10 USB ports), the motherboard may not support this function (many motherboards are only equipped for 4-8 USB ports). If the motherboard does not support a certain chipset functionality, this function will not work with the PC.
