That is a ridiculous assertion. The performance increase will be at least 10% or it would not be worth the effort. I expect a base clock of 4.0 GHZ on the 2800X and turbo of 4.5 GHZ. I sincerely hope a better IMC has been incorporated into this product so that people routinely can achieve the CL ratings of their dimms at the rated speeds. It would be wonderful to be able to routinely get dimms running up to 3600mhz or above if that is what your dimms are rated at.
But you know that Zen was in development for 4 years before the launch, right? So you're expecting quite a lot from the second gen, as it comes just a year later.
2 scenarios possible (and I don't think they had time and money to cover both):
1) AMD goes full gaming and they improve the consumer Ryzen lineup.
The variance of current Ryzen chips quality is very high, so I'd expect a more even product line. While the base clocks might go up by those 10%, it could be at a cost of boost or OC potential.
At this point, following AMD own statements and leaks, we shouldn't expect improved compatibility or features. It seems their core client base is OK with how Zen works at the moment - they just want it to become faster.
2) AMD solves the business lineup problems.
It's 2018 already and we're looking at almost zero enterprise/workstation utilization of Ryzen Pro, EPYC and Threadripper. It really makes you wonder if there is something wrong with these chips that we don't know yet.
This is from Ryzen PRO launch IN AUGUST:
http://www.amd.com/en-us/press-releases/Pages/ryzen-pro-desktop-2017aug31.aspx
It says that Dell Optiplex 5055 and Lenovo ThinkCentre M715 are "expected to ship in the coming weeks".
And these PCs exist!
You can find manuals for the Dell:

but it is not available on the page (to view/customize/buy).
The Lenovo is actually available to customize (not sure about ordering), but look at this.
I said a year ago that they will have a hard time selling business PCs with IGP-less CPUs, but I've never imagined the prices!
They charge you
$570 for Ryzen 7 + GT730 upgrade (base price includes a A6-9500).
GT730 is maybe $50-70, so why does the Ryzen PRO cost $500, when the retail model is $300?
Vendors usually have a big premium on these business PCs, but this is beyond reason. It doesn't look like Lenovo wants to sell these computers...
