Really hope that 16 core is AM4 compatible.

If these specs are true, I'd be curious if the high-TDP models will be fully supported on all AM4 motherboards. It is possible that they would run in a lower power state depending on the motherboard.

What else would they use though? TR socket? Seems a bit odd if they did

I'd assume it will be, sort of explains why a lot of the top end X470 boards have 8 Pin + 8 Pin EPS or 8 Pin + 4 Pin EPS
The TDPs on the leaks are pretty good. I think 1800X was also 125W? So I suspect they should run at least on more premium older boards like X370/X470 maybe B350/450 depending on the motherboard manufacturer.
For more detailed information on the latest Ryzen (and Navi) check out AdoredTV on YouTube. He had a 3850X that topped out at 5.1GHz, though it was expected to not be announced at CES

I so hope these are real as they are gonna be awesome if they are
All Ryzen processors but the 2700X have been sub-100W so far. The 1800X was 95W, 2700X bumped that up to 105W as the node had matured somewhat to allow a push further along the power curve. Given how AMD used a low power variant of 14nm, and that was the main issue with getting clock speeds or usable TDP much higher, it would make sense if 7nm no longer has these issues, and allowed a push to more traditional enthusiast TDP ranges(If you measured Intel's recent 8 cores TDP similarly to how AMD measures their TDP, you'd likely also get results in the 120W+ range, as their 8-cores can only stick to their rated TDP if you force them to base clocks/they're thermal throttled)
AM3 was only really designed for 140W processors though, but many motherboards had no issue with the later 225W models. Overclocking can make power use skyrocket in some crazy ways so a lot of manufacturers will put down that headroom.
An EPS12v 8-pin CPU power connector can easily supply ~225W while in spec, and a 4pin EPS about 150W (Using the conservative 75W per current carrying pair, important not to confuse CPU connectors with PCIe, very different pinouts) so you'd expect boards putting more than one CPU connector on to have VRMs that could actually support the 250W+ to make use of it.

the 1800X is listed as 95W on AMD's website. 2700X was 105W.

I’m thinking these chips will be half a Threadripper, as in two dies on a common substrate as opposed to four in Threadripper. If that is the case, I’m hoping that there is enough room for two dies on there and that it doesn’t involve a new socket. Does go to show how versatile Infinity Fabric is.

The 3700x looks interesting if those clocks are correct 12 core and a boost too 5ghz
AMD's committed to AM4 for 4 generations or till 2020 iirc, and with "big-socket" Ryzen parts pushing to 64-cores on Epyc, and with plenty of other differentiating features between AM4 and TR4 besides maximum core counts, I think it'd be a reasonable move to have upto 16 cores on AM4.
It makes sense from a viability perspective too, if they're using the same core dies for Ryzen2 as with Epyc2 (A business model that worked very well for them with Ryzen's launch), then said dies *need* an interposer and at least one other die (The I/O die, now decoupled from the core piece) already, so it wouldn't be a crazy leap for AMD to have models with three total die instead of two, as long as they could keep TDP in check to avoid throttling(Physically we know theres space, those 7nm dies are absolutely tiny from Epyc2's reveal images and the IO die will be specifically for consumers given PCIe3.0 use, fewer core dies, half the memory channels and all the other changes to uncore).

They're gonna pull an Intel on this one - new socket and chipset! :lol:
There's not really a reason for a new socket & chipset [Edit: As in one that breaks forwards+backwards compatibility with other chipsets/processors] (Technically all AM4 processors can work without an external chipset as they're complete SoC's, but overclocking and additional IO amongst other features require an external chipset) until DDR5 & PCIe5 arrive, both are expected to have availability in 2020(The first PCIe4 hardware was 7nm Vega & Epyc2 also supports it, though given how heavily delayed PCIe4 was, and that the relatively uncoupled development of PCIe5 has been ahead of schedule with an accelerated launch window, reaching standardisation within 18 months of PCIe4 as opposed to the 3/4s of a decade window between 3 & 4, I think it's expected that many consumer systems will skip PCIe4 altogether as DDR5 is lining up for the same launch period and PCIe5 would offer large improvements to efficiency of IO in mobile systems and the like).

I think the telling part here is 5ghz.
Usually when a Ryzen CPU has been able to reach a speed then they have all been able to reach that speed, or there abouts. And that may be why the 16 core is clocked lower, to meet the 125w TDP.
These also seem to be the desktop chips, with the 9 possibly added on the end to show off.
I will say something negative, though, so I don't get accused of rimming AMD. 5ghz for 7nm could very well be quite lame. Intel have managed to reach that speed on 14nm.
Mind you, it's not been much use to Intel on anything above an 8 core, because of the heat and power use. That may be where AMD really nail in some coffin nails.
Either way any Ryzen chip at 5ghz will certainly compete with what matters - what Intel are selling now. The ability to have a 12 core chip at 5ghz stock using very little power could be incredible.

I really hope the specs are true, will switch to AMD if they are.

Sandy to Ivy was a die shrink and the boards all worked. I really can't see AMD making you need a new motherboard. Mostly because they would lose more than they gain. IE customers, over sales.
The longer they can keep people on the same board the higher the chance they have of coaxing people into buying a new CPU. They may release a new chipset but they just have, so we will see. What they won't do (unless they're daft) is release the same socket with a different chipset that doesn't work on older chips, and vice versa. That would cause mass confusion.

I should imagine power support would be the same as Ryzen 2000 working on 300 series boards, in that like-for-like CPUs have similar power requirements. Bear in mind that the 7nm shrink gives either 1.25x performance at the same power or 50% power at the same clocks, so in theory you'd have roughly the same power requirements for a 16c/32t Ryzen 3000 on 7nm as you would a 8c/16t Ryzen 2000 on 12nm at the same clocks. I don't see any reason why a 12c/24t Ryzen 7 3700X couldn't work on a chunky X470 board, even with it's rumoured 5GHz boost clock.
But those 2 16c/32t Ryzen 9s will probably be locked to new X570 boards to be on the safe side; that anniversary edition 3850X is rumoured to have a 5.1GHz boost clock.
