They won't be able to clock as high as Intel's 4 core parts and their supposed desktop TDP advantage will not be as apparent(I would predict its worse than Intel by a fair amount) in lower voltage parts.

TDP advantage is primarily a marketing advantage.



90.3W for 6900K vs 117W for 1800X.



Ryzen is 9% faster than the 6900K in this bench, but it consumes 30% more power to get that edge (as an aside: 6950X consumes less power than 6900K does and outperforms the 1800X in this workload).

Perf/watt, not the perf/TDP, seems to be in favor of 6900K over 1800X. That's old Broadwell core, 1st generation Intel 14nm.


Also, here is the V/F curve for Ryzen from Anand forums:




Requires 1.4V to get 4GHz. Intel's old 22nm 5960X could hit 4GHz on all cores with just 1.075v. ASUS' overclocking guide said that 1.3V for 4.5GHz was an "average" result for old 22nm 5960X (https://rog.asus.com/articles/overclocking/rog-overclocking-guide-core-for-5960x-5930k-5820k/).

Ryzen mobile will have to go up against Kaby Lake Refresh-U and Coffee Lake, which should be built on another iteration of 14nm past 14nm+, which should further increase frequency capability for a given power consumption.
