Socket sTRX4, also known as Socket SP3r3,[1] is a land grid array (LGA) CPU socket designed by AMD supporting its Zen 2-based Castle Peak Ryzen Threadripper desktop processors,[2] launched on November 25, 2019 for the high-end desktop and workstation platforms.
Socket sTRX4 is the direct successor to Socket TR4 used in the first- and second-generation Ryzen Threadripper products. It is physically identical to, but electrically incompatible with, both TR4 and AMD's server Socket SP3.[3][2]
While Socket SP3 doesn't require a chipset, instead utilizing a system-on-a-chip design, Socket sTRX4 and its predecessor require a chipset to provide improved connectivity and functionality. For Socket sTRX4, the TRX40 chipset was developed, which provides a total of 88 PCIe 4.0 lanes,[4] an increase from the 66 PCIe 3.0 lanes on its predecessor platform.[5] Also it no longer features a built-in High Definition Audio interface; instead motherboard manufacturers are including a separate audio controller onboard to provide audio functionality.[6] AMD has promised long-term support for socket sTRX4.[7]
