14nm not competing for server, but for pc we get 9900@ 4,4 157 watts, 3700x @ 4,2 140 watts stress test. Suppose that 10700K@ 4,3 can also be under volted by 0,1 and oc'ed by 200mhz. And AMD had to go for 7nm second gen node n7p to get that. We are yet to witnesses rocket and coVe with great ipc. So 14 nm will kick ass even when amd is on 5Nn.
