STRX4 and TR4 socket differences are published for AMD Ryzen Threadripper 3000 Series processors

A few days ago AMD introduced the new Threadripper 3960X and Threadripper 3970X. These new processors require a new socket due to a restructuring of the pins. Hwbattle has published the pin differences between the sTRX4 and TR4 socket. Apparently there should be no compatibility problem with processors based on the TR4 socket. What's more, the two sockets are physically the same.

Already the first rumors about the Threadripper indicated that AMD would not offer backward compatibility. First there was talk of a blockade by chipset, but in the end it has to do with the socket. Physically, the dimensions and the number of pins of the two sockets are equal. Even motherboard manufacturers have specified that their new motherboards are not compatible with previous Threadripper.

The sTRX4 and TR4 pin design has been published, showing the differences. The new sTRX4 socket enables a large number of non-active pins on the TR4. Both sockets have the same number of pins, 4,094, but the sTRX4 has more enabled.

Apparently AMD would have implemented a pin recognition system to match the compatible CPUs with its socket. This would ensure that it only works with the third generation Threadripper. If a second-generation Threadripper processor or earlier than the sTRX4 socket was installed, the system would not turn on.

A technique used by Intel with the LGA 1151 socket, which with each new generation, forces to change the processor. In this case, AMD would have done so to accommodate 64-core processors, which will require more power. Highlight that AMD has committed to this new socket has a great longevity.
