Here is the complete zeppelin die. Outside of the 2 CCXs, there are SerDes and mem controller, each of which is about the size of a Zen core. Assuming the failure is completely random and catastropic, the chances of getting the "dead" dies could be just as common as getting 6 functional cores...
My wild guess would be that some of the dies have broken memory/PCIe controller which could very well be considered catastrophic regardless of how many cores would otherwise be non-defective. There are bound to be those kind of dies would it?
If we pay attention to the cache size in that table, we will see that the 7920X has 16.5 MB cache. By taking the highest-clocked variant with 16.5MB cache, we only get the Xeon Gold 5118 with 2.3/3.2 GHz in the link below...
The $999 one is for the 1950x the top-end 16c/32t so this does not invalidate the BnC's claim yet. BnC was only speculating $850 for the bottom-tier 16c/32t, which could very well be the vanilla 1950 (analogous to the vanilla 1700).
At least, gluing 4 "mainstream" dies to form a server CPU is still better than gluing 1 mainstream die to a bigger socket and call it a HEDT.
Sorry, I couldn't resist posting this.
In this screenshot it's not 8 CCX of course, but rather 8 dies in total for this setup since this system is 2S Epyc (pay attention to "2 processors" in the system information). Now looking back to the Ryzen with only one die, that's equals to just 1 NUMA node.
Now the question is, would Windows...
The minimum may not be necessarily true though, but nonetheless very likely. Remember that the 16c EPYC still have twice the PCIE lanes and DRAM channels while still having the same core count. That said, the 16c TR is made of the full-fat ccx and will have higher clock speed. So, the pricing...
Here is the "source" of the Platinum 8180 score.

Which can be roughly translated, with my rusty knowledge in Chinese to:
Judging by the poster's tone, he seems to be disappointed with the performance and thermals he get...
That 8-core part... That one is likely be 1 core active per CCX. I wonder how much yield of those dies with that bad of a defects.
I expect that AMD will not make this too appealing price-wise to the mass, or they will have to cripple the better dies for it.
Hmmm, that could mean up to 25-30% advantage in the Multi-threaded performance for the 18c i9. More than what I once estimated.
Oh boi...
Btw, I am curious to see if those Xeons are soldered or TIM'd. That would also somewhat influcence how much clock speed those i9s would have without...
That's all depends on the clock speed wouldn't it? It's worth noting that 18c is "only" 12.5% more than 16c, multiply that with the IPC advantage of 10% for the total of about 24%. This 24% is the (hypothetical) maximum all-core clock speed advantage TR allowed to have over the SKL-X's 18c parts...
On the same clip, what is the 2442 cb score doing here with the 7900X on 2:27? Would that suggest this is the pure 7900X performance when the thermals has yet to kick in during the first run?

And they have to use toothpaste instead of soldering to the IHS with the price reduction.... oh dear...
To be fair, there is no problem with the paste, but let's hope that the gap is...
I am curious about one thing. The R9 SKUs are supposed to be in 4CCX configuration (with 4 cores in each) and the disabling of the cores should be uniform across all CCX's they amalgamated together. Now, that means the existence of 10 and 14 cores do not possible unless AMD is actually using two...
I did said in the other thread that the Ryzen's DF is already running 1:1 with the memory clock. The "2666 MHz" DDR4 speed is rather 2666 MT/s with 1333 MHz due to its "double data rate" nature. To make it "1:1" as you described would actually mean 2:1, unless AMD can somehow make DF being DDR-like.
Come to think of it, I have one question. Does the Optane support tied to CPU or tied to the Chipset? From what I know so far, either Kabylake or 200-series Chipset has support for optane. If the support is tied to the CPU, then it comes into the other question: whether or not the SKL-X has...
The only "appeal" it that this SKU appears to be a stop-gap for the Skylake-X to come. Although having the "newer gen" being a herald to the "older gen" does not make much sense to me either.
Turns out those circuitry on the reddit earlier apparently a fake, debunked by a chinese site.
The reddit post linking to the chinese site: https://www.reddit.com/r/Amd/comments/61fc4c/x390_and_x399_leaks_are_fake/

That reminds me of the commotion about ryzen's DF being "half the memory clock". The "2400 MHz" is actually a misnomer and should have been read as "2400 MT/s" and the RAM itself would actually be operating at 1200 MHz. Unless the ryzen's DF is actually operating at 600 MHz, we could put to rest...
There is one fishy thing in the video. In some of the runs he showed, the framerates were quite different while the frame times were quite the same.
For example, 13:07 https://youtu.be/TId-OrXWuOE?t=13m7s
Are there any dark magic here, or this is some kind of timer error?

Now M$ won't let you update Win7 with ryzen/kabylake. Really? Microsoft... Really? This is getting too far.
Would be nice if someone has tried to compare that paste's performance vs. the aftermarkets. This going to be interest to see if the stock paste is worth wiping off or not.
The 1400x is going to be the $200 Haswell i7-k on a newer platform w/o integrated graphics. Whether that is a worthwhile investment is anyone's decision.
Take that result with a grain of salt for now. I have had a look at the comment section and the reviewer said that He forgot to disable the "double buffering" on the 7700k part. Now that it is disabled, the result is here...
http://www.tomshardware.com/reviews/amd-ryzen-7-1800x-cpu,4951-4.html
Bear in mind that the 6900k is tested with Quad-channel RAM and the Ryzen itself has crappy latency at its current form. IIRC, the DFT/FFT is memory intensive, so taking away the advantage of quad-channel and the result could...
My $0.02, this is from a layman so take this with a huge pile of salt:
If the wonky coreinfo dump on Ryzen CPU really is how Windows sees the logical cores being mapped to the cache and handles the the way it is (as opposed to being just a "wrong presentation"), then the Ryzen right now may...
So, this confirms that Ryzen does really supports windows 7, even better so than windows 10. Oh the irony. :p
Any idea when this thing is going to get fixed?
Based on the slide it says "twice the xfr headroom" for x versions. If this is true, the vanilla 1700 will clock to 3.75 Ghz on single core.
Let's see how that goes on the real reviews.
