TL;DR: First Zen OPN and PCIe info leaked. Additionally I do a recap of some other recent leaks.
Planet3DNow! forum user "Crashtest" posted a Zen ES OPN and PCI device info (behind the spoiler button), which somehow landed in the CPU-Z and SIV databases.
So the OPN is "1D2801A2M88E4_32/28_N". Using the already known schema, "D" stands for desktop, "28" for the base clock frequency (2.8GHz), the first "8" of "88" for the number of cores. And more clearly, "32/28" stand for turbo boost frequency (3.2GHz), and the base clock again (2.8GHz). This matches the information given for the 8C DT ES in an AnandTech forum posting recently:
"The most exciting part is core clock. The 8c/95W variant's base clock is 2.8GHz, all core boost is 3.05GHz and maximum boost is 3.2GHz."This hasn't been confirmed in this way before (except that I heard it is true). So until now there was nothing available, that actually supported the information posted there.
The PCI information found in the SIV database looks as follows:

Update #1: As "Crashtest" explains in a later posting, the respective Summit Ridge system (w/ Myrtle mainboard) seems to have at least 36 PCIe lanes. According to him, the listed configuration seems to be a bit chaotic. BTW, "Promotory" should actually be written "Promontory".
Update #2: Thanks to the OPN, Planet3DNow! user "BoMbY" identified some Ashes of the Singularity benchmark results, which were run on two different Zen engineering samples. One had the same OPN, while the other had a slightly different one ("2D" instead of "1D"). As they've been removed from the AotS database, you can find them archived here.
Next there was a BitsAndChips article about the likely provider of the DDR4 PHY found on Zen based processors: Rambus. That speculation is based on the given details the author learned from his sources, which fit well to what Rambus recently announced regarding their 3200 Mbps DDR4 PHY available for Globalfoundries' 14LPP process. You can learn a bit more about their technology here.
Another interesting bit of info are two AMD roadmaps, which look real. But as one recently could see with this Athlon X8K die shot posted at Reddit, even the quality of die shot fakes can be rather high (also see my analysis there). In that case the creator of the die shot wrote me, that he actually just tried to check the viability of such a product regarding die size and thus processing costs. Back to the roadmaps.
For 2017 they show:
- Raven Ridge APUs for the FP5 socket (4C/8T, <=12 gfx CUs, 4-35W TDP)
- higher TDP models (65-95W) for the AM4 socket (also 4C/8T and an unknown number of gfx CUs)
- also AM4 based Summit Ridge CPUs with 8C/16T and TDPs of 65 to 95W
There is also a notable difference in the listed processes: "14nm SoC" for Raven Ridge, and "14nm FinFET" for Summit Ridge. I assume, that the "14nm SoC" process might refer to a different metal layer density, as recently covered in an article by Hiroshige Goto (Japanese) about APUs and AMD's FinFET efforts. Thus "FinFET" could stand for less dense lower metal layers, which would allow for somewhat higher clock speeds due to lower wire delays.
A note on the slides: I saw some unusual pixel patterns and spacings in the "14nm SoC" and "14nm FinFET" boxes (aside from different sizes). I'd expect a scaled, interpolated PowerPoint slide to show subpixel positioning of single characters. But I saw only pixel exact 1 or 2 pixel spacings with exactly similar interpolated pixels around the characters. I'll try to reproduce this in PPT.
In the end, these slides (if real) might mean, that there is no desktop Zen available in 2016 (even not as the promised sampling at the end of the year). But that is not for sure, yet. My own GCC patch based launch speculation gave a rough launch date range between 10/2016 and 05/2017.
Update #3: You can find the complete two slides and an additional one here. These don't look like being faked, although some details look a bit awkward. But this might be attributed to a smaller target audience (I suppose decision makers with more interests in dates and specs).
I was wondering whether this could also be a possibility for what the Zen S/N are referring to based on the leaks and rumors that have been floating around.
1D - Desktop Variety
28 - Base Clock Speed
01A - Model & Stepping
2M - 2 Multi Core Modules (4 + 4 Core Chips Joined)???
88 - 8 Physical Cores | 8 HT Cores
E4 - Revision Number
32/28 - Base/Boost Frequency
N - Retail Ready Check / Final Validation Check ???
I found this nice page for help with decoding the OPNs: http://www.cpu-world.com/info/id/AMD-ES-identification.html. This should explain most of the numbers.
The "1" before "D" (which is for desktop) might be more related to some ES stage, I suppose. "Z" could be the final one based on that.
Logical cores/total threads are not encoded. Thanks to the new Zauba leak, we know, that this ES should have 16 threads capability.
The "N" is the only new component. It might just mean to have no gfx.
Matlab Assignment Help helped me to complete my seventh Matlab assignment, which was also the best-performed! It scored 92/100, which I've never scored before on any other assignment/exam in my lifetime. Otherwise, their service was as quick as usual. The delivery was also on time. I'm now requesting to use this same programmer multiple times. He seems the best in Image Processing tasks. Meanwhile, I'll ask for more Matlab Homework Help soon.
Besides my C course, I have a job and family, both of which compete to get my time. I couldn't find sufficient time for the challenging C assignments, and these people came in and saved my skin.
