The suspicion is that those first numbers are for Engineering Samples... So who can guess what numbers for what comes out in production when finally announced/released?

That the numbers are for ES is also my impression. I went and looked at the current EYPC specs and the top turbo is 3.2GHz. And that is available on the 32 core count chips (@$5,000 new).

I have observed a strong inverse relationship between core count and cpu speeds on Intel cpus. The higher the core count, the slower the cpu.
The ThreadRipper 2990x claims a maximum turbo of 4.2GHz. The Ryzen 7 2700x claims a maximum turbo of 4.3 GHz.
Server cpus usually have much lower turbo speeds than even Workstation cpus because they are presumed to need to run 24/7 without any bumps.

I claim, therefore, that the EYPC line MIGHT have a top turbo on the order of 3.5GHz for the ROME generation. So any system production that is effected by not having at or near 4GHz cpu speeds will find the EYPC not suitable as a replacement Workstation cpu.

Since AMD has currently dropped the TR line from the announced plans, that gives them the possibility of announcing an upgraded 2970x/2990x CPU chip with the memory channel bottle neck fixed at a later time. Part of the question would be if the upgraded 2970x/2990x had to use the EYPC MB socket to get around the memory channel bottle neck.

On the question of future 8 channel TR's, yes they would absolutely have to change to the Epyc socket. I have read musings that the clocks on the Zen 2 Epyc and possible TR3 parts would be lower than previous generations and they would make up performance by 50% better IPC than previous generations.

Looks like not only will you be able to drop a Ryzen 3000 in to existing motherbords after a BIOS update, but some of them will also support PCIe 4.0 (at least on the main PCIe slot).

We’re mere 5 days away from the announcement of AMD’s highly anticipated next generation Zen 2 based Ryzen 3000 series CPUs which are set to make their debut next Monday on the 27th of May. In the meantime however, we’ve got a whopper of a leak for you to keep you entertained.

Two of AMD’s upcoming flagship Ryzen 3000 CPUs have been leaked. And if this leak holds any water, and with this source we certainly expect it to, then these chips are going to be absolute beasts.

Just found a bios update for my Biostar (AM4 socket) TB350-BTC motherboard. It announced some update version change to "Agesis" but didn't come right out and say, update for next Ryzen version of AM4 socket cpu.
--edit--
Found this in the Wiki article on AGESA.

Then in March 2019, the third iteration of AGESA, named "ComboAM4 PI", was released, starting at version 0.0.7.0, introducing support for Zen 2-based processors

The version I just flashed does say "ComboAM4 PI" so I presume I can upgrade to the 16 core/32 thread Ryzen 9(?) cpu.
--edit--

It took an hour to run the bios update using the internal bio flash program. Since the "other" flash program runs under windows and I am using Linux on this MB... I just have to wait forever is all :)

Yes the combo BIOS is one that can handle the legacy processors along with the new Zen 2 processors. The BIOS size is double what it used to be and why it took so long. The 0.7 combo is just the first iteration of the BIOS. The AGESA level for the combo BIOS is up to version 1.0 now. Each manufacturer spends a different amount of time vetting the new BIOS before releasing it to their own products. The AGESA code comes from AMD, not from any one manufacturer.

X570 chipset motherboards revealed:

https://wccftech.com/asus-x570-motherboards-teased-rog-crosshair-viii-rog-strix-tuf-prime-series/
ASUS has teased their next-generation AMD X570 chipset powered motherboard lineup which will be ready for AMD Ryzen 3000 CPUs. The new motherboards include some of the most iconic ASUS series, offering users a wide variety of motherboards to select from when they launch in the 2nd half of 2019.

https://wccftech.com/msi-meg-x570-ace-and-x570-gaming-plus-motherboards-amd-ryzen-3000/
MSI has just unveiled its next-generation X570 chipset powered products for AMD Ryzen 3000 CPUs which will include the MEG X570 ACE and the X570 Gaming Plus boards.

https://www.tomshardware.com/news/msi-x570-motherboard-reveal-specs,39411.html
VideoCardz already leaked the Gaming Plus motherboard a few days ago, but the MEG X570 Ace had never been seen before. It is basically a more high end version of the Gaming Plus, with three full 16x PCIe slots, three M.2 slots, a post code display, two 8-pin connectors, robust VRM and chipset cooling, two (yes, two) Ethernet ports, five audio jacks, an optical audio port, five USB 3.1 ports, two USB 3.0 ports, one USB type C port, two Wi-Fi antennae connectors, a BIOS update switch and CMOS reset switch. This is likely the highest-end board ever made for the AM4 platform aside from the Crosshair VII Hero from ASUS.

MSI also commented on the chipset fans, saying they were necessary due to some "speedy" additions to the chipset, which likely means PCIe 4.0. It is not certain under what exact conditions this seemingly overkill chipset cooling is required, though one rumor is that NVMe RAID using PCIe 4.0 is the main reason.

If some of the CPU leaks hold up, I won't be able to upgrade to 16c/32t CPU because the MB TDP is too low. My AMD Mb will be able to go with a 12c/24t CPU, however.

Do any of the announced 3rd gen MB have 6 PCIe slots?

Who knows!? None of the vendors have released official products yet, just leaks by third party online websites. You will have to wait for Computex next week for official announcements.

Linus Tech Tips video with a lot of information about the new CPUs and motherboards.

Asus coming with 30 x570 motherboards. One of which has water cooling around the PCIe 4.0 slots and on the PCIe 4.0 chipset, because it gets so hot (as it draws 11 Watts)

That's the good News. The bad news is the only cpu that would tempt me at the moment (more cores) may not be able to run reliably on my 350 series motherboard. The MB claims 95 watts. The 12 core cpu claims 105 watts.

Darn. I guess I will look at MB's next.

Would this massive amount of 70MB cache for the ryzen 9 3900X will impact seti@home run time?

And here is a 6 slot MB.

Plus verbage and a picture I haven't been able to get the right url for on an MSI prestige X570 Creation which has 6 slots.

Here is an I can't find it anywhere 8 slot MB:https://www.asrock.com/mb/AMD/X370%20Pro%20BTC+/

The ASUS Prime Pro series has always been a solid performer. I started out with the X370 Prime Pro.

Actually that board has seven slots.

Which should make it the best choice, so far, for an AM4 Boinc motherboard. That presumes that it will run all 7 slots and maybe an extender.

Has anyone seen anything about the next Threadripper series?

After having the AM4 Socket stop at 12c/24t it now looks like there is still "room" for the TR's.
Don't get me wrong, it still looks like the 2920x might be in trouble because of the 3900x but... it would be really nice if the TR came out with both the Zen2 improvements and the memory bottleneck fixed.

There still is the 16C/32T Ryzen 3000 model to debut. I predict it won't show up till later this year. I still think Threadripper 3000 will appear eventually but not until next year first or second quarter.

I think the 16C Ryzen 3000 chip is going to be matched with either the X570 chipset variation that is in the ASUS Pro WS X570-ACE workstation motherboard or a completely new variation of the X570 chipset. That motherboard is doing something completely different from every other motherboard.

First it supports ECC memory and second it supports X8/X8/X8 PCIe Gen. 4 slots. So they are delivering an extra 4 lanes out of the chipset that no other board is doing. There was talk that with the full fat dual chiplet 16C Ryzen 3000 model with its full 64MB of L3 cache, that there would extra PCIe lanes coming out of the cpu.
