Processors Ryzen Threadripper

TR4 , also called SP3r2 , is a CPU socket from AMD with 4094 pins. It can accommodate CPUs of the Threadripper series, with which AMD serves the high-end segment. They are based on the Zen architecture.

TR4 supports DDR4 memory with quad-channel connection and up to 128  GB per RAM module, has 64 PCIe lanes and uses the X399 chipset (related to the X370) .

In contrast to the AM4 socket , the TR4 is not designed in PGA , but in LGA technology. It is mechanically identical to the socket SP3 for the server processors called EPYC , but not compatible with it.

Launch

The socket was introduced on August 10, 2017 with the first generation of the AMD Ryzen Threadripper generation. The second generation of the AMD Ryzen Threadripper CPUs was presented at Computex 2018.

In November 2019, AMD presented the Threadripper 3000 series, which requires the successor socket sTRX4 .
