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, an increase from the 66 PCIe 3.0 lanes on its predecessor platform. 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. AMD promised long-term support for socket sTRX4. Despite This, AMD only gave it one generation of CPU's before discontinuing the regular Ryzen Threadripper Lineup (the only product to ever use sTRX4) and producing only the Threadripper Pro CPU's on Socket sWRX8
