Lenovo and AMD Launch Threadripper Pro CPU To Take on Intel Xeon (cnet.com) 26
AMD finally brings a workstation-class -- in other words, security-conscious -- processor to challenge the Intel Xeon on the desktop with its Ryzen Threadripper Pro. With up to 64 cores, the pro version of AMD's multicore powerhouse Threadripper processors incorporates essentials like support for massive amounts of memory and board-level security, critical for uses which move a ton of sensitive data, ranging from aerospace visualization to Hollywood video editing and CGI rendering. The CPU debuts in Lenovo's ThinkStation P620; Lenovo has a limited exclusive on the processor. From a report: The CPU comes in four variants: 3945WX (12 cores, with the fastest single-core speeds), 3955WX (16 cores), 3975WX (32 cores) and 3995WX (64 cores). At the moment, to achieve core counts that high with the Intel Xeon, you have to use multiple CPUs. They all come with some of the perks of AMD's architecture, including support for PCI Gen4 -- in this case, up to 128 lanes. And the Pro versions add support for more types of memory, notably RDIMM and LRDIMM, over the high-end consumer-focused Threadripper, plus 8 memory channels vs. 4, which lets it support up to 2TB of memory. On the downside, while AMD supports faster internal transfers than Intel via PCI 4, it doesn't offer any high-speed external data transfer capabilities a la Thunderbolt 3. And in fact, the ThinkStation P620's fastest connections are USB 3.2 Gen 2 and 10Gb Ethernet.

Or very least we need desktop socket amd boards with IPMI and ecc.

Why would a desktop board need ECC or IPMI? Those are workstation and server class options that make no real sense on the desktop.

A workstation is often a desktop, just a high level desktop.
3990 and 3995 are both threadrippers, the difference is that the 3995 have more memory buses and can address more memory, so less of a bottleneck when handling memory-intense operations. Not every application needs a higher memory bandwidth so the 3990 is enough for a lot of high end.
I'm just waiting for someone to put together a gaming rig with the 3995WX when it comes out - just because they can.

I can see ECC on the desktop, but not IPMI. Why would you need that?

They also have some IPMI-equipped Threadripper options; like the X399D8A-2T.

It's called the Ryzen Threadripper Pro, so the acronym would be RTP and thus the names should have been RTP12, RTP16, RTP32 and RTP64. Maybe add a number after R to denote which Ryzen generation they are.

Your lineup "RTP12, RTP16, RTP32, RTP64" may work fine today. But what are you going to call the variant of RTP32 that is binned for higher clock speed or more cache?
I sympathize with you. The model numbers of CPUs (especially Intel) are overwhelming. But when they are made in many different fabs and production processes, with varying yields (causing all kinds of combinations of cache and #cores), for desktop, laptop, workstation, low-power versus performance, different socket types, it's hard to come with

Finally they have registered DIMM support. Next up, motherboards?
This is a great step and eats into the remaining niches Intel had an edge in. About the only thing left after this is funky machines with more than two sockets.

The consumer market for CPUs doesn't turn much of a profit. The server market is where AMD ate Intel's lunch.

Interesting that the description for the socket reads:
Are there any estimates for how these new CPUs compare to the current gen. when they arrive in the fall?
* 12 cores: 3945WX vs R9 3900X @ 3.8 GHz
* 16 cores: 3955WX vs R9 3950X @ 3.5 GHz
* 24 core: ??? vs TR 3960X @ 3.8 GHz
* 32 cores: 3975WX vs TR 3970X @ 3.7 GHz
* 64 cores: 3995WX vs TR 3990X @2.9 GHz

Must be doing really well. (Score:3)
If AMD is giving attention to desktop workstations then they must be selling server chips like hotcakes. The consumer market has thin profit margins so if they are willing to put in the effort to push a high-end workstation chips then they are either selling server chips quickly or are desperate to sell anything. Considering Intel has been hemorrhaging since Meltdown was found and the slow trickle of Spectre flaws, I'm willing to be AMD is doing quite well.

Looks like the WX got a slight performance bump on the low end but a decrease on the high end??? Level1Tech has this video [youtu.be] where they give some specs:

I'm all-AMD myself but TB3 on an add-on card will be slower than Intel's integrated solution due to having to go trough a PCIE bridge.
TB3 and TB4 both have 40 Gb/s signalling rates. That's 2.5 lanes of PCIe gen4. Aside from some small latency penalty for the TB - PCIe interface, there's plenty of bandwidth available with a PCIe Gen4 x4 card.
You could have 3 TB3/4 ports at full capacity with an x8 card.
