IMO the trx80wx will support Epyc also.

I do not know how to help you farther as I do not know where you are confused.

There is no electrical or physical reason that Threadripper 3 cannot work in X399. The only reason it would not work is if AMD decides they do not want to support it, in which case I expect that will be "solved" quickly, as 9900K in non-Z390 boards was.

You are talking with the same guy that kept going and going mistaking the current drift velocity with the speed of a electromagnetic signal. It took pages to talk him out of his mistake.

He's not worth it, really.

I'm not confused at all. I am just taking pleasure in trying to lead you around to understanding the compatibility issue, and finally grasping an understanding of it while doing so in the most (insert word we aren't supposed to say on these forums here) way possible since that is how you have chosen to start the conversation and thus have it presented back to you in the same manner.

Oh? If you will remember correctly, that argument was (and apparent still is?) about the velocity of electricity in a vacuum not being the same as the velocity of electricity through a medium such as copper wire, and whether the amount it slows down as wires get into nanoscale sizes and there is less electrons and resistance is rising substantially starts to matter at all in CPU design. I claimed the velocity does change substantially and comes into play, you claimed that current speed and wave speed are different things over and over and over like you got stuck in a loop. Which had no bearing on the topic being discussed and you didn't seem to be able to move past that. Still dont seem to be able to actually.

Today OCN sets a new low: "Less electrons".

I'm out of here because this can only end with me laughing my way into a permaban.

Ah now I understand the confusion. You think there is a compatibility problem.

There is not one. This has already been proven. Case closed.

two atoms are walking down the street.

one says "oh snap, I lost an electron!"

the other asks "are you sure?"

"yeah, I'm positive"

Remember the golden rule of statistics: A personal sample size of one is a sufficient basis upon which to draw universal conclusions.

There may not be a physical compatibility problem, but that does not mean they are compatible. TR4 does not have the same requirements of the motherboard as SP3, so motherboards made to the TR4 spec do not meet the spec for an SP3 cpu and are not considered a valid configuration.

Most of the reason for a new socket designation and forced break in compatibility is because the design spec for the motherboard side has been changed.

You see this with socket 1151, the power spec was changed in line with the higher boosting power requirements on the 6 and 8 core chips, which meant that motherboards designed for the 4 core cpu spec weren't considered compatible.. but if you remove all the safety and validation checks those chips can boot and run on a board that's built well enough to not be damaged by the extra load. But the boosting behavior of those newer chips on older boards is wrong, it doesn't boost properly at stock.

If I had to guess, I'd say the design spec for SP3 motherboards had pci-e requirements good enough for pci-e 4, but the spec for TR4 probably didn't in an effort to make the boards less expensive.

Explain 3900X on B350 then. The board, and even the chipset, do not need to support PCI-e 4.0 for the CPU to work in the socket. It can run in 3.0, just like when you put Ryzen3 in a Pre-X570 AM4 board.

Power is not a valid argument either, as 7nm draws far less per-core of it than 14/12nm did, and nearly all of the X399 boards are severely overbuilt.

As a reminder, the rumor is that TX40 will be a 4-channel board that supports up to 32-cores. X399 is a 4-channel board that already supports 32 higher power consuming cores.
