The Xeon Phi x200 (Knights Landing) has a lot of modes of operation (selected at boot time), and the latency and bandwidth characteristics are slightly different for each mode. This reduces the number of “hops” required for request/response/coherence messages on the mesh, and should reduce both latency and contention.
