TRX40 and TRX80 are a new generation and a new architecture. Nothing to do with the past generation.

Strange that Rome could be compatible with motherboards designed for Naples, or Matisse with motherboards designed for Pinnacle Ridge, but Threadripper 3 can't be compatible with motherboards designed for Whitehaven.

How trustworthy is your source on this? It seems reasonable if AMD is overhauling Threadripper (personally, I've thought that it might end up being 8-channel, like Epyc but unlocked) but unlikely if they're sticking to quad-channel/64 lanes. Obviously they can't have PCIe 4.0 support on existing X399 motherboards, but I expected the CPUs to work.

Good points, especially the bit about "Rome could be compatible with motherboards designed for Naples, or Matisse with motherboards designed for Pinnacle Ridge, but Threadripper 3 can't be compatible with motherboards designed for Whitehaven".

I am an AMD shareholder (so far, so good) but like the Ryzen3K boost clock fiasco, this whole next-gen TR business (above, plus earlier TR 'slide disappearance' gate) shows that AMD needs to get better, clearer communication instructions out.

My firm, which uses mostly Intel server / work-station products, was ready to shift more productivity machines to TR, with X399 mobos et al in reserve. This followed our first AMD TR purchase last winter, with AMD suggesting socket compatibility for at least one more gen...I guess it is best to wait for real release / review info now before making any other AMD related purchasing decisions. Shouldn't be long now...

That is definitely unfortunate to hear. Means at least 1-3 new motherboards for LN2 testing. I will be interested to see how this is all turns out.

I'm definitely looking forward to see what AMD and the board partners bring to the table in terms of memory channels and possible speeds available.

Curious how true this is...
https://www.gamersnexus.net/news-pc/...-channel-leaks
If so, this would be kinda ****ty for the TR platform as sWRX8 platform has all the PCIe lanes, yet no OC support while the sTRX4 has ****ty PCIe config - assuming 16x PCIe 4.0 would just downclock to 16x PCIe 3.0 and not to 8x PCIe 4.0... I for one have 2 video cards and 6 NVME and would love to OC the memory a bit.

With Ryzen3K showing that oc'ing (other than may be PBO) is not that fruitful as with CPUs 'in the olden days', the TRX80 platform might be interesting if one has a lot of PCIe cards...I just hope it will support non-ECC as well as ECC, as I scurried away 8 sticks of Sammy-B 3866 already. That said, it would be nice if the current X399 would support at least TR3-32c...I can live w/o PCIe 4.0 for a while

I really hope that 12 and 16 cores threadripper will have something more than pcie lanes and quad channel to justify the hedt platform over the mainstream one.

While I have no plans to upgrade, that is certainly disappointing for those who where wanting to stick with their current Mobo's.

I personally think that manual OC for Intel and AMD moving forward will be less and less fruitful. Both companies are now generally maxing out their silicons at factory, without the need for a hard manual OC like we used to in the past.

1) The announcement is scheduled for November 7th and so far I have not seen microcode's for the X399. For X470, the first microcodes I already had in March. For example.
2) The socket has a different revision.

You're far, far closer to this than any of us, and clearly, AMD's original next-gen TR plans were changed earlier int he year. The only thing which gives me a bit of hope for X399 and TR-3 is this statement from GN' mobo documentation re. backward comparability of some CPUS: "AMD’s document notes that sTRX4 and sWRX8 are single-socket client platforms that use surface-mount LGA sockets supporting Family 17h models 30h to 3Fh, which seems to include some previous generation CPUs."

In my mind, that sounds a bit like X450<>X570, and TR-3 not validated for X399 sounds a bit more like a mobo vendor favour by AMD, especially with the full-tilt sWRX8 available as a separate option.

AMD come one where is the threadripper announcements?

They still not officially launched 3950X where is the threadrippers. Come one.
