hello Hilbert!
what if the 7945 is a 32c 7985 a 64c and the 7995 a 72c?
greetings!

350w for 96/192 is impressive.

tbh, if gpu prices didn't explode i'd be all over this for my home.
as is, with mobo, this calls for work to pay for the workstation especially with multi-channel large volume DDR5 sticks.

Calling this HEDT is disingenuous at this point given that the pricing is all workstation level. HEDT died when AMD released the 3000 series TR and Intel half-heartedly released 10000 series LGA 2066 chips and nothing again. It's really sad to see because it used to be possible to get extra PCIe lanes and DRAM bandwidth without breaking the bank.

Genuinely curious: ignoring GPUs, what to you is the difference between HEDT and workstation, either 5 years ago or today? I've always seen them as basically the same thing, where GPUs and marketing being the only real difference.

not sure about the etymology, but for me a "workstation" was having 40+ pcie lanes, with at least two x16 slots
but in common usage many hedt's are workstations, but not all workstations are hedt's. primarily based on processor, chipset, and usage
in the "bad old days" of four core hegemony, hedt's had the only cpu's and chipsets capable of more, plus the native ability to run SLI/Xfire from the cpu lanes without relying on chipset lanes
but after more capable cpus and gpus came out, what was marketed as hedt (TR) were really workstations with or without the "W" prefix

i think whether its hedt really comes down to the motherboards, threadripper and epyc are bascially the same products since the beginning, but the motherboards for thread ripper dont have to cost $800-1000, tr4/trx4 were basically cost reduced motherboards, and amd hasnt done that since threadriper 3000, if amd launches 4 or 6 channel boards i think you can call that hedt, if they stick to 8-12 channel as wrx8 or sp5 does, then its as you say.

HEDT always held the spot between desktop and workstation. Intel's HEDT didn't support ECC and generally had lower DRAM capacity to differentiate itself from the workstation counterparts. They were basically cut down workstation parts that you could overclock as their Xeons weren't overclockable. This meant the prices could be lower as Intel's volume customers couldn't afford to be limited by the DRAM and would buy the more expensive parts. AMD destroyed Intel in that market starting with the 3000 series and with the 5000 series were literally the only choice that made sense. When they did this the HEDT market was destroyed by the extremely high cost of entry and nobody has tried to resurrect it.

Wasn't much of the old HEDT scene destroyed by the regular CPUs having up to 16 or 24 cores (with Intel's efficiency ones)? It left the traditional HEDT a narrower space to exist in, so it makes sense it was shifted to a more premium direction. Of course if you do consider it from the pov of PCIe, then the mainstream CPUs having 16 full cores doesn't matter, as they had no more PCIe lanes. Perhaps this sort of view only works when you look at it from the perspective of the decade of degeneration (4 cores maximum for the mainstream). So, now that 16 (24) cores is a part of mainstream, you might say HEDT should have been redefined. However, with Intel having been absent from it, I reckon AMD had little interest in doing that. With lack of competition, AMD could hike up the prices and make the scene kind of inconsistent and unpredictable. I don't know the market situation, but my gut feeling is that AMD rather sold more EPYC than TR units.

AMD killed Intel HDET and castrated their own HDET with Ryzen having 32 threads with 3950x.
I've love to replace my 1st gen thread ripper. 1920x, 64gb DDR4 3000 and x399 taichi.
But no way in hell will I get the same kind of deal again.
New TR CPU to equal 1920x core count or better will cost more then I paid for the board, CPU and ram.
I'll just get a 2990x one day, and go up to 128gb of ram and keep it will the board dies. Hopefully another 10 years.

Lane count.

my 5950 replaced my TR and my 7900X3D is gob-stoppingly powerful - even in the context of 1st gen TR. and i'll buy a 7950 soon to replace the 5950 as the cost of DDR5 has dropped enough to make 4 sticks reasonable
the reality is that pro applications have taken over the TR marketplace, especially for "content creators" and Hollywood production companies that use the extra pcie lanes via the slots - whether storage, capture, or A.I. accelerators
the hedt that we knew has been replaced by the i-9 and the Ryzen 9 w/o the extra lanes - as gpus don't need xfire/sli anymore.

While the absence of more affordable motherboards is an issue I get ... Why would you be bothered if they keep 8-12 channels? You can run it with "just" 4 or 6 channels can't you?
user1
Yeah but how else am I gonna get 100gb/s reads on my 8xnvme raid 0 array:D
not really bothered, just worried about cost, while it definitely is possible for vendors to build 4 channel boards for an 8 or 12 channel platform, that basically never happens irl, so if amd specs it for 8 or 12 channels , we'll basically have the same situation with wrx8, likely with >$1000 boards which sucks .
Venix
Yeah cost is an issue but how much making a mb 4 channel instead of 8 saves ? 10 bucks 20, 30? So if a board is meant to cost 400 might get bumped to 450 witch is fine .... I think the main problemis that they just charge so much because they can 🙁

Title says "Updated: Ryzen Threadripper 7945WX, 7985WX and 7995WX Zen 4 (4 Cores Up to 5.1 GHz)"
4 cores?! LOL!

the cost increase is pretty steep, mainly because of the complexity , some of it is markup, but its definitely not cheap to design and build 20-30 layer motherboards
