Socket TR4, also known as Socket SP3r2, is a zero insertion force land grid array (LGA) CPU socket designed by AMD supporting its first- and second-generation Zen-based Ryzen Threadripper desktop processors,[1][2] launched on August 10, 2017[3] 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.[4][5] It is physically identical to, but electrically incompatible with both AMD's server Socket SP3, and Socket TR4's successor socket, Socket sTRX4.[3][6]

While Socket SP3 does not 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 PCIe 4.0 lanes for quad SLI/CrossFire configurations.[7]

The socket is made by both Foxconn and Lotes.[8]
