Socket SP3 is a zero insertion force
Zero insertion force (ZIF) is a type of IC socket or electrical connector that requires very little (but not literally zero) force for insertion. With a ZIF socket, before the IC is inserted, a lever or slider on the side of the socket is m ...

, SATA controllers etc.) are fully integrated into the processor package, eliminating the need for a chipset to be placed on a motherboard. Variants for desktop platforms (as said below) are, eventually, requiring an additional chipset to unlock the functionality of the CPU. A processor using socket SP3 is mounted by inserting the CPU into a slide and fixing the slide assembly by tightening three screws using the torque wrenches normally provided alongside the motherboard. Automated processor mounting tools in OEMs do not use the slide, instead relying upon the precision movement of the robot arm.
Socket SP3r2
Socket TR4, also known as Socket SP3r2, is used for high-end desktop CPUs. It is physically identical to a normal SP3 socket with some connections disabled. A TR4 socket will prevent the use of CPUs designed for Socket SP3 with an ID pin.Socket SP3r3
Socket sTRX4, also known as Socket SP3r3, used for third-generation Ryzen Threadripper (Threadripper 3000X) high-end desktop CPUs, is physically identical to the normal SP3 socket with some connections disabled, and is the successor to Socket TR4 (SP3r2).Socket SP3r4
Socket sWRX8, also known as Socket SP3r4, is used for Ryzen Threadripper Pro 3000WX and Ryzen Threadripper Pro 5000WX workstation desktop CPUs. It is physically identical to the normal SP3 socket, with some connections repurposed.See also
