if those clock under 4ghz after you overclock this is not a good sign seems weird though

Canard, if as reliable in the past as you say, is ripping up their integrity posting such bogus. The chances of this being legit is probably 5%.
But if this was perhaps a mobile chip..

This actually makes sense.
You're getting a genuine Quad Core against intel's G4XX line up which consists of two physical cores and HyperThreading.
Get a B350 motherboard and clock it up to a solid 3.8~4.0 GHz and you have a really sweet deal for the price AMD sets.
I can't see these Quad Cores coming out with a Base Clock of anywhere near 4.0 GHz. A Base Clock around 3.3 GHz to 3.6 GHz with boost up to 4.2 GHz would be ideal, but I am sure these Quad Cores are going to be the bargain deal. I expect the 4 Core 8 thread counterpart to take on the likes of the Core i3 K SKU and the 6 Core 12 thread to take on the likes of Core i5 and maybe 7700K, though I think AMD's original intended competitor against the 7700K is the RyZen 7 1700.

It makes sense. Of course AMD doesn't want it's 4 core CPU to beat the 6 and 8 in single thread performance out of the box.
I do however expect it to clock higher than 4Ghz and that's were the sweet spot will be.

Maybe AMD will use in the beginning all those CCXs that have 4 fully functional cores but can't clock high enough to be used in a Ryzen 7 1700. After they got more CCXs from GlobalFoundries and have enough to start building every model in the Ryzen series at high quantities, they will introduce faster quad core models.
Remember, AMD is not Intel. GlobalFoundries is not Intel. They both have restrictions at the same time that Intel doesn't know how to fill it's factories' product lines and where to spent all it's money sitting around.

Such a CPU plus a cheap mainboard might be my next HTPC, just to toy around with it. 😀

This makes sense. Due to the current state of multithreading in most games, it would be embarrassing for R5 to clock equal or higher to the R7. If if clocked slightly higher, you might get R5 overtaking R7 in some games... for half the price.

Could be a process limitation. Ryzen seems to need a LOT of voltage to get past 4 GHz.

What´s the surprise??? It has been said many times by Canard PC and others that the best chips are all going to be used on the R7 versions. The weaker chips not only are going to have less cores but also lower clocks because of weaker power profiles. And from what i understand, the 4 and 6 cores versions will reach the same overlclocks of the 8 cores parts.
This has been talked about since the beginning, if it´s true or not, we´ll have to wait for reviews.

I'm not surprised, if those chips are only leftovers from worse silicon bins of 8 core cpus then it stands to reason that clocks will be worse along with non-working cores.
There is albo a production process limitation 14nm LPP that while giving low power use at lower frequencies forces a very steep climb for voltages to keep stability at higher clocks. AFAIK the 3.7Ghz is a tipping point after which steep voltage increase is required to increase clocks. There will be no high clocked 4 core parts because of that, not because of power use (although it plays it's role too).
Also if AMD gets it's 4 cores by the way of cutting cores from 8 cores it may mean even worse performance then in case of 8 cores because they probably will not be able to disable one CCX but will have to cut 2 cores off from each CCX, just as the can't do 6 core by disabling 2 cores from one CCX and leaving the other untouched.

Also if this is a leftover silicon lottery from the 8core CPUs makes me wonder about something that AMD did in the past. With certain Phenom II Cpus you could enable the cores that were disabled for whatever reason and if it worked you could have a Quad-Core (if you have a tri-core) and a Hex-core (if you has a quad) Makes me wonder if AMD could be going that route again?
As far as clock speed goes I hope that this isn't true because I feel that AMD needs to compete their Quads with Intel's Quads as well.
BLEH!
Depends on how many different dies AMD have. If these are harvested from 8-core dies then I can understand it, if they have a distinct 4-core die then maybe not.

so much for that one
