How much untapped potential does Zen have? With Zen being a completely new architecture, I like to think that Zen is in the same stage as Nehalem was and that the next big revision of the architecture would bring a big performance bump similar to Sandy Bridge. Intel seems to be stuck on Skylake. Kaby Lake is Skylake rebadged. Coffee Lake is basically a price-cut of Skylake: more cores for about the same price. Obviously, with Intel's architecture being much more mature than AMD's, there simply isn't much room for Intel to easily squeeze out more performance.
