Ah, but how many will be binned like that?

[Or do we really expect this to be reflective of the average?]

I will let you all know when I get mine (the minute they are available.)

Honestly I would guess so, I mean AMD probably could be using a golden sample. But with higher Boosts I assume it should have higher OC ability even specially if we are talking about just an extra 100 MHz or so.

I Don't see why not.! I am sure that they not only binned the CCD but also the CCX, so only the best of the best are going to 3950X, TR3

That is a pretty decent all core OC, especially for 16 cores. Also, 1.4V is decent for a Ryzen 3k chip, considering they boost to around 1.5V normally. I wonder what the load power draw for that chip's OC was though.

By comparison my "bad" chiplet on my 3900X does 4.3GHz at ~1.34V. And the "good" chiplet does 4.4GHz at ~1.34V. My 3700X does 4.3GHz all-core on less voltage, and 4.4GHz @ 1.368V.

I'm not terribly impressed by 4.3GHz all-core @ 1.4V. That suggests to me that the 3950X may have the same binning strategy as the 3900X - 1 "good" chiplet, and 1 "bad" chiplet. If so, I'll probably skip it in favor of waiting until 2020 and Zen 3.

Are those static volts, at static all core clocks? What windows power plan?

Yes, yes, and AMD Ryzen High Performance using the latest chipset drivers and AGESA 1003AB

However, I find OCing to be pointless for daily use because at stock my Ryzen 3700X boosts in the 4250-4275 range during gaming loads while staying under stock power limits. At stock settings it is giving me comparable gaming performance to my OC 8700K while using literally 1/2 the power.

Does it maintain static boosts during the entire gaming time, or does it fluctuate??

Fluctuates by 25-50MHz depending on load. But keep in mind my boosts are limited by the older AGESA. I would suspect that once 1003ABBA is available for my board it will be closer to 4275-4300 typical boosts while gaming. Supposedly AGESA 1004 is coming in November, which may further improve stock performance.

They are all crap and crappier chiplets.
AMD hasn't enough capacity to have good chiplets for the desktop.

They have plenty of capacity. And they have good chipslets for the desktop. What are you talking about ?

1.4v? Ouch. That's actually kind of bad for anything high-current (which CBR15 isn't really, but still). They probably didn't run 1.4v actual, but instead used default UEFI settings and wound up with some vdroop. Still kind of high for that workload, though. They should be able to pull 4.3 GHz somewhere in the 1.25-1.3v actual range. I can do 4.3 GHz on an x570 Aorus Master - same board as the linked article - with 1.248v according to CPU-z. That's with LLC off and -.1v offset. Ryzen Master reports 1.375v. I think they may just have a "meh" sample or they just didn't spend a lot of time tweaking settings to get that voltage down.

edit: the above is with a 3900x. 3950x should take about the same amount of voltage for the same workload at the same clockspeed. Should.

The CPUs are good, no doubts about that.
The chiplets though are bottom of the barrel.

Compare the Threadripper 1 and 2 launch with Threadripper 3.
It seems the initial release will be a 24 cores not a 32 cores, i.e. not a fully functional chip.

Lets see if the 3950X isn't delayed again and if it will be more than a paper launch.

"aren't the top bins" is a lot different from "they are all crap and crappier chiplets" and "the chiplets though are bottom of the barrel".

So you're telling me the 3800X single chiplet with all 8 cores enabled is "bottom of the barrel" and "crap and crappier" chiplet? The one that draws 20% less power than the 9900K but comes within 5% or beats it in basically all tests? Right.
