I don't believe the video, its suspicious that there are two of them and none are 8 core 16 Thread, if you're going to leak why not the top of the range 8 core? why the middle 6 core? I wouldn't be surprised if its the 8700K on LN2.
I don't know what Ryzen 2 / Ryzen + will end up being but its not the 5Ghz 7nm that some people seem to think it is, that comes later... this is Globalfoundries 12nm, what was originally meant to be 14nm FinFet+ (IE Ryzen+) but is now plain 12nm FinFet, which has a 15% increase in circuit density and 'over 10%' improvement in performance, what AMD might do with an extra 15% die space 'if anything' is anyone's guess but comparing at least 10% performance improvement is an easy one, Current Ryzen runs at 3.6Ghz base clock with a 4.1Ghz XFR, so that should turn into 4Ghz all cores and perhaps as high as 4.5 or 4.6Ghz XFR. XFR = single core boost.
With some 'low hanging fruit' tweaks i don't see why AMD couldn't also get another 5% IPC gains, i think that's extremely likely especially given that Infinity Fabric in Ryzen 1 is the first iteration and in its infancy. that would bring the Ryzen 5 2600X inline with Coffeelake 8700K, the Ryzen 7 2800X would be that much faster.
Using that 15% extra die space for a larger L3 cache could also increase the IPC some more.
IMO AMD are going to be very competitive during 2018, Intel have shown thier hand and its just another Skylake with higher clocks and two extra cores, AMD can deal with that and i think they will starting early 2018
