AMD SP3/TR4 socket pinout maps

AMD’s Land Grid Array sockets for the Zen-based processors are changing the industry as we know it. With the latest generation of EPYC, these sockets carry CPUs featuring up to 64-cores (EPYC 7702P).

At HardwareBattle pinout layouts for the SP3 and TR4 sockets have been shared. As a reminder, the TR4 is not the same socket as sTRX4 for the next-gen Threadripper 3000 series. So far, no one has released a map for this socket.

The author of the maps goes in detail to explain that the differences between Threadripper and EPYC sockets are minimal. However, for obvious reason, AMD does not allow cross-compatibility between both platforms.
