For example when AMD compares Zen to Broadwell E at the same clock speed, it may mean that the Broadwell-E was declocked to Zen levels. If Zen will be able to achieve 3.5 GHz stock core clock, it will be on the same level of performance as Broadwell-E/EP CPUs. In smaller thermal design envelope. Zen is 95W CPU in 8 core configuration, and is direct competitor for i7-6700/K, not Broadwell-E/EP.
