Clock speed increases are a likely benefit we'll see when Zen 2 is released on Global Foundries 7nm+ process, right now that's the biggest reason Zen seems to fail against Kaby Lake in single-threaded performance minus some minor IPC differences. A Ryzen 7 1800X tops out at 4GHz boost (it can usually run stable at 4GHz overclocked with a vCore bump, but you're playing the silicon lottery) meanwhile a Core i7-7700K has a base frequency of 4.2GHz - a 5% difference, ignoring the 7700K's 4.5GHz boost frequency.
On a similar note, it looks like fab processes are likely hurting AMD with their GPU's. From what I can gather they opted to produce Vega at GloFo's fab on their 14nm proccess, which might explain why they are shipping the air-cooled Vega 64 with a 1.24GHz base clock at a pretty ludicrous 295W TDP.
