AMD Threadripper Pro 5000 Series Spec Leaks

There has been some discussion as to whether or not AMD would launch any Zen 3 based Threadripper processors or not, considering that the desktop processors have been out for well over a year by now. According to igor's Lab, we now know that AMD is very close to launching some new 5000-series Threadripper Pro CPU's—codename Chagall—that fits into AMD's sWRX8 socket, which is intended for high-end workstations and servers.

It appears AMD is planning to launch five new CPUs, namely the 5995WX, 5975WX, 5965WX, 5955WX and 5945WX. All of the CPUs appear to have a maximum, single core boost clock of 4550 MHz and range from 12 to 64 cores, with a TDP of 280 W and a power range of 170 to 260 Watts. Up to eight channels of DDR4 3200 MHz is supported and up to 128 PCIe 4.0 are expected to be featured as well. For those hoping there would be an HEDT version, we have bad news, as based on what we've found out independently and the information provided by igor's Lab, there won't be any HEDT Chagall CPUs, at least not at this point in time. This means that the upgrade path for sTRX4 motherboards ended up being as bad as for the older TR4 motherboards, as AMD has now abandoned two HEDT platforms in a row.

No 3D-cache and 2P configuration (2P is not supported in sWRX8 platform)?
Doesn't sound right.

2P is only for servers, not Threadripper. As for 3D-cache you might be correct from those numbers.

SWRX8 will be a dead end after this too. AMD workstation platforms are a bad investment when their desktop components in the next gen are likely to be faster than their current HEDT parts.
Guess they didn't learn from Intel completely screwing the high paying HEDT market.

A 5950x isn’t faster than a 64 core zen2 part in any tasks that these are intended for.

why would you ever get a threadripper platform if you don’t need the cores, the IO or the memory bandwidth? It would be a bad investment on day one.

4.5Ghz boost? Err, no, that's the absolute max of the chip and these will get nowhere near it. It clearly states 2.7-4.1GHz

It clearly states that the 2.7 to 4.1 GHz is the all core clocks. 4550MHz is for limited core counts.

the chips can probably boost as far as 5GHz with some tuning. (So not at stock settings).

Well, it's their own "fault" for launching a HEDT/workstation platform so late.

But regardless, these platforms offer vastly more IO options and ECC, which are very useful for "work" computers.

Looks like these chips start at where our desktop models top out. If you can keep them cool they should hit full boost. But! It’s not easy to keep 7nm cool at 260w.. at least with air..

It really isn't that bad, these cpus will have more chiplets which means they might have lower heat density than the AM4 cpus.
Threadripper also have much bigger IHS for contact

This is the last HEDT that I have bought from AMD.

Tell me, which "work" applications require all the IO? Most work only requires one dedicated accelerator (if any) and high end AM4 offers enough USB/LAN.
many high end x570 boards support ECC so there goes that argument.

Leaks.. why not call it the pre-announcement release of the scheduled announcement just incase there is a pandemic or some other natural disaster that would force them to postpone the hyped date...

This is a loaded, stupid leak.. What about we wait and see what AMD actually do..

I doubt AMD is going to abandon Threadripper, considering how hard and successful their push with them were into a number of areas where an EYPC isn't needed but something more than a Ryzen was. That said, I suspect they're going to release a final batch of sTR4 Threadrippers with 3D V-Cache alongside the refreshed AM4 Ryzens. It would be the perfect opportunity to do so before they reset and restart with AM5/TR5 and DDR5/PCIe 5.0 solutions.

Compare the number of "leaks" on AMD and Intel , I would say the AMD ones looked like "leaks" and Intel ones are PR stunt

Sorry, I should have made HEDT bold. The workstation platform is sWRX8 and the HEDT platform is sTRX4.
The 5950x is faster than the 3970X is quite a few tasks. Many 3D modeling applications will run quicker on the 5950X in everything other than rendering, and only about 30% slower in rendering which is often able to be offloaded to the GPU. In these cases you could easily afford another RTX 3090 for the cost differential and run them at 8x (negligible performance drop in everything especially rendering) for way higher performance on the AM4 platform.
Not everything used on a workstation is purely multi-threaded CPU crunching.

My point was that the upgrade path makes the overall cost of the system much more economical. If one had bought AM4 with the 3950X, you would get 2 additional generations of double-digit performance increases. I would hazard a guess that the 5950X equiv with 3D cache will be knocking on the door of the 3960X for multi-threaded workloads and smashing it in single thread.

AMD should not have stated publicly that the switch from X399 to TRX4 was to improve the upgrade path for the platform. It's becoming quite clear that was not the plan, it was to sell higher priced motherboards.

Yeah i knew AMD was full of BS when they said TRX40 was going to have long term support.
The change from TR4 was unnessesary as in the server market AMD kept SP3 but still managed to make newer CPU's compatible.

But TR4 was abandoned after two generations and by the looks of it TRX40 had only one.
Not to mention the massive price hike with RTX40 as soon as AMD achieved dominance over Intel in this segment. This is why we need competition. Having any one company dominate a segment is never good for the consumer.

Very few need all the IO, but quite a lot of users benefit from more IO than the mainstream platforms offer.
Many power users wants a GPU, 2-4 M.2 SSDs and a 10G NIC, plus many content creators wants capture cards etc.

And why would you have bought a threadipper if 3950x would have been fast enough? It’s plain stupid to get it ”just because”, if you didin’t need the cores, io or memory bandwidth.

Is there would be any HEDT and price will be above anything a consumer wants. I still remember that TR 2990wx was released Intel pushed its Xeon 3175x but was not as good as 2990wx was. There after there is no news from Intel to release further HEDT (specifically X series). Only Amd TR 3000 series and pro dominated and this would not be challenging if Intel comes up with a new HEDT.

I wonder if AMD is updating the TR mobo spec to allow for 2P options; according to Tom's, there supposedly is a 2P TR Pro mobo that was tested using existing 3000 series TR Pro CPUs. It'd be interesting if the halo end of Non-Pro TRs could include a few 2P mobos, allowing for low-core, high-clocking TRs to be paired up (say 2x 12c or 16c Threadrippers) and managed via liquid cooling.
