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 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.[7]

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