So they artificially downclocked an Intel processor, and are able to *barely* beat it clock-for-clock. But that Intel processor should be running at a higher clock speed, and if they have it fixed at 3GHz then they also turned off Turbo Boost - which would have pushed the Broadwell-E chip up to 3.5GHz when all 8 cores are active. At those speeds, presumably, the Intel chip beats the AMD; if not, they wouldn't have bothered to downclock the Intel processor.
To sum up then: AMD's next-gen, unreleased processor still cannot outperform Intel's existing model. This doesn't surprise me, though: ever since Intel caught back up with (and then passed) AMD's performance - starting back with the first Core series processors - AMD has been trying to catch up... and failing. They do have a role in the low-price / budget system market, and maybe this new Zen stuff will cost a lot less than Intel's offerings. It doesn't look like it will truly rival Intel for high performance applications, though, where the fastest speed is worth a few hundred dollars more. After all, in the grand scheme of a several thousand dollar workstation a few hundred dollars isn't a huge deal - and 5, 10, or 20% performance difference could easily pay for itself over time.
