A CPU socket uses a series of pins to connect a CPU’s processor to the PC’s motherboard. If a CPU is connected via a CPU socket, it is not soldered and can therefore be replaced. CPU sockets are more common with desktop gaming PCs than they are on laptops.
When buying a motherboard, finding the best motherboard isn't just about making sure it has the features you want. Step one is making sure the motherboard has the right CPU socket (and a supported chipset) for your CPU model.
Even if you have the best CPU, it won't work with just any CPU socket. Intel has different socket types for its mainstream CPUs versus its high-end desktop (HEDT) ones, as does AMD.
Intel and AMD CPU Sockets
Below we break down the consumer CPU sockets for current and prior generation Intel and AMD desktop CPUs.

Intel users can also figure out which CPU socket their chip uses with Intel's directions on this page and use Intel’s Product Compatibility Tool to see which motherboard fits your CPU.

I was looking forward to a treatise of how modern CPU's use their many, many pins, and got only a teaser that told me nothing new.
