1 Chipset
The chipset is a collection of controller chips that manage the flow of data between the CPU and other components. It might be hidden under a heatsink, as in the image opposite, but it's present on every board. Different chipsets support different processors: Intel's 13th generation Core processors can only be used in a board that uses one of the company's 600-series or 700-series chipsets, while AMD's Ryzen 7000-series CPUs need an AMD B650 or X670 chipset.
The chipset doesn't just determine what CPU you can use. It also dictates other technical features of the motherboard, such as whether it works with DDR4 memory or requires more expensive. DDR5 modules, and how many PCI-Express lanes and USB connectors it has. You don't have to research the technical details of the chipset before buying a PC, though you can just check the features of the board itself.
2 CPU socket
Intel's 12th and 13th-generation desktop processors use the LGA1700 socket format. The letters stand for 'land grid array', meaning the socket contains 1,700 tiny pins, which press against a grid of flat contact points on the base of the processor. Installing the CPU in a socket like this is a simple case of dropping the chip into the housing and locking it in place with a latch.
For AMD's Ryzen 7000-series processors, the socket AM5 connector is an almost identical LGA design, with 1,718 pins. Older Ryzen CPUs use PGA (pin grid array) sockets, where the motherboard mount has thousands of tiny holes and the pins stick out of the underside of the chip. The two designs are electronically identical but PGA is more fiddly and it's easier to bend or break the pins.

Intel's crazy plan for 1nm silicon
FIVE NEW CHIP PRODUCTION NODES in four years. That was Intel’s plan to get back to technology leadership. It has now added a new 1nm lithography node to its roadmap, due in 2027. But here's the thing: in terms of products to buy, Intel has achieved little of its original plan. So, what’s going on?
