AMD Ryzen Threadripper Pro 5945WX and 5995WX Surface

AMD is looking to launch a substantial lineup of HEDT and workstation processors before the end of 2021, based on its latest "Zen 3" microarchitecture. These processors are categorized in two distinct lines—the Ryzen Threadripper 5000X targeting HEDTs, and the Ryzen Threadripper Pro 5000WX targeting workstations. Both are based on different sockets, sTRX4 and sWRX8, respectively, with the latter featuring 8-channel DDR4 memory, compared to the former's 4-channel. Two Ryzen Threadripper Pro 5000WX series chips surfaced on the Milky Way@Home distributed computing database, the 5945WX and 5995WX.

The application identifies the 5945WX as a 12-core/24-thread processor, while the 5995WX is the top-dog 64-core/128-thread part. AMD maintains lower core-count Threadrippers to target the section of the market that seeks I/O capabilities over core-counts (memory bandwidth, a large number of PCIe lanes supporting NVMe RAID or multiple AIC compute accelerators, etc,). The lower core counts also come with higher CPU clock-speeds, benefiting less-parallelized applications. At this point it's not known if the Threadripper 5000 family features the conventional "Zen 3" CCD chiplet, or the new "Zen 3+" chiplets with 64 MB 3D Vertical Cache (3DV cache), but the company is planning to monetize the new chiplet across its EPYC enterprise line as the additional cache benefits certain applications with large streaming data-sets. It's conceivable that the Threadripper Pro series could benefit from 3DV cache, too.

Like 4K @120fps 4:2:2 ProRes RAW and 8K video, especially when you have a >5 camera setup.

LoL i really would like to play with one of these on the WRX8 motherboard with all 8 channels filled
The smallest version is good enough ;)
But i fear the price will be somewhat of an issue for a home user xD
And then i could post can you play games on it : yes / NO NEVVA :D

The pricing is honestly not that outrageous for all the features you get. It was about a 35-40% premium over the desktop Ryzen parts for the 3000 series. But the motherboards available for WRX80 are like 3-4x as expensive as B550/X570 to make use of those extra lanes I suppose.
16-core with only 24 PCIe lanes, dual channel memory, ECC somewhat supported (non-registered only, so no server RAM): $799 + motherboard (let's assume $300), total $1100
16-core with 128 PCIe lanes, octochannel memory and qualified ECC support (both registered and unregistered): $1149 + motherboard (let's assume $800), total $1950. Memory isn't necessarily any more expensive either since it can run both unregistered and registered memory meaning it can run both desktop and server memory.
If you have a usecase for the extra lanes and/or extra memory, or need qualified ECC memory support, TR Pro is a damn good deal. I'm eyeing up the 16-core Zen 3 part myself to swap out my 5950X.

I know this a just a leak, but apparently both TRX4 models and WRX80 cpu model's will be released at the same time this go around. So coming out two months later (November) More selections at this Threadripper launch. I'm only disappointed they won't have 3D V cache, lol.

I don't think there is a 16-core part compatible with the WRX80 platform, and hence no octa-channel RAM.

Uh.. Yes, there is. 3955WX. Right now there's 12, 16, 32 and 64-cores on TR Pro/WRX80, those being the 3945WX, 3955WX, 3975WX and 3995WX. There was a rumored 3965WX (with 24 cores) being considered but it was scrapped prior to launch according to rumors.
