Socket TR4, also known as Socket SP3r2, is a land grid array (LGA) CPU socket designed by AMD supporting its first- and second-generation Zen-based Ryzen Threadripper desktop processors, launched on August 10, 2017 for the high-end desktop and workstation platforms. It was succeeded by Socket sTRX4 for the third generation of Ryzen Threadripper processors.
Socket TR4 is AMD's second LGA socket for a consumer product after the short lived Socket 1207 FX. It is physically identical to, but electrically incompatible with both AMD's server Socket SP3, and Socket TR4's successor socket, Socket sTRX4.
While Socket SP3 doesn't require a chipset, instead utilising a system-on-a-chip design, Socket TR4 and its successor require a chipset to provide improved functionality. For Socket TR4, the AMD X399 chipset was developed, which supports a total of 64 PCI Express lanes for quad SLI/CrossFire configurations.
