Socket SP3

Socket SP3 is a land grid array CPU socket designed by AMD supporting its Zen- and Zen 2-based Epyc server processors,[1][2] launched on June 20, 2017.[3] Because the socket is the same size as Socket TR4, and Socket TRX4, users can use CPU coolers designed for not only those sockets, but CPU coolers designed for sTR4 and sTRX4.

It's a system on a chip socket - that means most features required to make the system fully functional (such as memory, PCI Express, SATA controllers etc.) are fully integrated into the processor, eliminating the need for a chipset to be placed on a motherboard. Variants for desktop platforms (as said below) are, eventually, requiring additional chipset to provide improved functionality of the system.

Socket SP3r2
Main article: Socket TR4

Socket TR4, also known as Socket SP3r2, is used for high-end desktop CPUs. It is physically identical to a normal SP3 socket.[4] A TR4 socket will prevent the use of CPUs designed for Socket SP3 with an ID pin.[5]

Socket SP3r3
Main article: Socket sTRX4

Socket sTRX4, also known as Socket SP3r3, used for third-generation Ryzen Threadripper high-end desktop CPUs, is physically identical to the normal SP3 socket, and is the successor to Socket TR4 (SP3r2).[6]
