With two processors installed, the two processors are connected together using one UPI link. With four processors installed, the processors are connected together using a ring topology, using two UPI links, one to each adjacent processor in the ring.
Processors with the T suffix have more robust thermal characteristics (higher T-case). Processors with the M suffix support support greater than 768 GB per processor.
