The Intel top x-series (that competes with Threadripper) only has 36 cores (not 70+), is limited to a single socket, and it's not shipping yet.

Even with dual sockets 70+ cores is not easy (or cheap) and other things like memory performance become more important than core count. AMD has a bandwidth advantage with single and dual sockets having 8 channels per socket instead of Intel's 6.

Intel doesn't have competition with 4 or more socket systems, but that topic drifting pretty far from a thread discussing Threadripper.
