16nm ARMv8 SoC for servers and workstations

8 DDR channels. Seems like everyone putting 30+ cores on a chip needs to learn this lesson. Memory bandwidth is the bottleneck. Intel uses HBM stacked on the Xeon Phi. Anyone who has the capability should do likewise or maybe try 8 DDR channels, pin count be damned.

This is what AMD's new Epyc server CPUs are rumored to have.

Quite more than a rumor at this point. The Eypc has 4 Ryzen dies, each of which on an on chip 2 channel memory controller.
