Last year we spotted that AMD was in the market to hire a new lead product manager for a ‘workstation division’. This was a categorically different position to the lead PM for high-end desktop, and so we speculated what this actually means. Today, AMD is announcing its first set of workstation products, under the Ryzen Threadripper Pro branding. However, it should be noted that these processors will only be available as part of pre-built systems, and no corresponding consumer motherboards will be made available.

Taking Threadripper To Pro

The product stack from AMD has included Ryzen Pro and Ryzen Mobile Pro hardware for a couple of generations – these processors offer ECC-enabled variants along with corporate support on security, manageability, and operating system image consistency. Most of us had assumed that while Ryzen had a Ryzen Pro variant, the most natural variant to Threadripper was AMD’s EPYC processor line of server processors. The server market and the high-end-desktop/workstation market have always sort of overlapped, and up to this point if a user was interested in a workstation-like design, with ECC and software validation, they would look to EPYC.

Today AMD is changing that dynamic with Ryzen Threadripper Pro.

Ryzen Threadripper Pro hardware will mirror single-socket EPYC in its features: eight memory channels up to DDR4-3200, 128 lanes of PCIe 4.0, support for RDIMMs and LRDIMMs, support for secure memory encryption, support for DASH manageability, and operating system image consistency as part of AMD’s Pro Business Ready programme.

Where Ryzen Threadripper Pro differs is in the core count/frequency/TDP configurations.

AMD Ryzen Threadripper Pro
AnandTech Cores Base
Chiplets TDP DRAM
3995WX 64 / 128 2700 4200 8 + 1 280 W 8 x DDR4-3200
3975WX 32 / 64 3500 4200 4 + 1 280 W 8 x DDR4-3200
3955WX 16 / 32 3900 4300 2 + 1 280 W 8 x DDR4-3200
3945WX 12 / 24 4000 4300 2 + 1 280 W 8 x DDR4-3200

There is also a small difference in DRAM support – TR Pro supports up to 2 TB, but EPYC supports 4 TB. All of the Ryzen Threadripper Pro processors are single socket only.

The top processor, the 3995WX, will offer all 64-cores. It goes above and beyond the traditional top EPYC 7742 (225 W, 2.25 GHz / 3.4 GHz) and even the 7H12 (280 W, 2.6 GHz / 3.3 GHz), by offering more base frequency at 2.7 GHz and a much higher turbo frequency at 4.2 GHz for 280W TDP. These processors might be taking advantage of the same manufacturing update as provided by the recent Ryzen 3000XT processors in order to drive these higher frequencies.

AMD says that its core count and frequency configurations are designed to suit a variety of different licensing models, for software that has licenses per core (where the high frequency models are recommended) or per socket (where more cores are recommended). 

OEM Only

One of the interesting elements of TR Pro is that it is set to be an OEM only product. This means that interested parties will have to talk to Lenovo or others in order to obtain the hardware. As it stands, Lenovo is set to be the launch partner for the TR Pro family, where it will be offered as part of its ThinkStation P620 family. Lenovo will offer its P620 in all different flavors, with up to 1 TB of DRAM and dual RTX 8000 GPUs (or four RTX 4000 GPUs).

Lenovo’s P620 use the socket in a rotated orientation to aid with airflow, but this also limits the socket to only one DIMM per channel, hence why we have the 1 TB max memory support. The system will use a lot of Lenovo’s ThinkStation innovations, such as removable fans and drives and such.

The target with something like the P620, much like the target of EPYC, is to replace both high-end single socket setups but also to replace dual socket workstation setups as well. Lenovo is set to position the P620 TR Pro version to cover both its P520 single socket and P720 dual socket products.

The ThinkStation P620 will be available to consumers from late September.

At this time none of the other OEM workstation providers have commented on their offerings, however by the end of the year I can imagine a few other offerings in the market aimed at different verticals.

Technically this system uses a WRX80 motherboard. You may remember an article I published early this year in January, stating that TRX80, WRX80, and Intel LGA1159 doesn’t exist. In that article I spoke to the traditional consumer motherboard manufacturers, as well as one OEM, none of whom had TRX80 or WRX80 on their roadmaps, and with AMD partnering exclusively with Lenovo for this product line, we can see why – the traditional consumer/HEDT motherboard manufacturers weren’t part of that collaboration. No WRX80 motherboards are set to be sold at retail, and the CPUs will not be sold at retail either.

We asked AMD about this, given that Ryzen Threadripper Pro is being positioned against Intel’s Xeon W-3200 and Xeon W-2200 series of processors. Some of these processors are available in a boxed form, and others are sold as tray parts to consumers, and there are a number of commercial motherboards available for each. AMD’s response was simple – with their product line, they felt it was not suitable to develop a new consumer product category under its portfolio. To those ends, TR Pro and WRX80 are going to be OEM-only for the time being. For anyone interested in TR Pro coming to the regular on-shelf market, let AMD know.


AMD’s main competition here is going to be Intel’s own workstation line of processors. If you haven’t been following what Intel is doing, not to worry – it’s somewhat of a confusing mess. Let us take it in stages:

  1. Before Intel launched Xeon Scalable, it offered variants of its E5-2600 processor line as ‘workstation’ models, such as the E5-2687W v2/v3/v4. These were socket compatible with Intel’s high-end desktop processors without ECC, or could be used in server-grade motherboards with ECC validation.
  2. After this, Intel launched the Xeon W-2100 family, built upon Skylake, and offering up to 18 cores with quad-channel memory. These were on the LGA2066 high-end desktop socket, but required special motherboards that used server-only chipsets. These were updated with Xeon W-2200 variants, built on Cascade Lake.
  3. Alongside this, Intel had Xeon W-3100 and Xeon W-3200 workstation processors, for the LGA3647 socket, enabling six-channel memory and offering up to 28 cores. Intel even offered a special W-3175X model that was overclockable.
  4. Now this year, Intel added the Xeon W-1200 family to its workstation lineup, using the consumer LGA1200 socket, but again with motherboards that have a server-only chipset installed. These W-1200 actually replace the E-2300 processors, and the Xeon E family has been mothballed into Xeon W.
  5. On top of all this, Intel has Xeon Scalable Cascade Lake which have also been used extensively in workstations.

AMD’s argument here is that TR Pro will compete with all of Intel’s Xeon W offerings. Where Intel has 80+ different options across a variety of sockets, AMD will have only four that will cover most of the market, and Ryzen Pro for the low-end.

Naturally AMD believes they are onto a winner, and much like the 64-core Threadripper 3990X was pitted against dual Xeon 8280 processors, AMD has done the same with the 3995WX:

The one thing missing is that AMD will not publish official MSRPs for its new processors. Because these are OEM only, the company states, they will not publish any pricing. This makes performance per dollar comparisons very difficult to manage.


AMD is launching its new Ryzen Threadripper Pro product line with its launch partner Lenovo, as part of the new ThinkStation P620 series. The P620 will be available from late September. These new processors will only be available as part of OEM pre-built systems, but will offer better core/frequency combinations than AMD’s EPYC processor line in a single-socket only variant.

Unfortunately AMD isn’t sampling these processors to the press for review, instead stating that we should ask Lenovo for P620 sampling. We’re looking into it.

    Thing is, that pricing makes it cheaper and more affordable for people who buy the low-core versions. This is what economists call "discriminatory" pricing, and it allows people who buy the low-tier product to be subsidized by people who buy the high-tier. Often, the low-tier price covers only the marginal cost of each unit, while the high-tier price covers fixed costs like R&D and real-estate.

    If this is using the full EPYC I/O, why is there even a chipset? Wouldn't it basically be just a glorified USB controller to complement the 4 USB ports that the CPU provides? Who's going to use anything else from it?
  • PixyMisa - Tuesday, July 14, 2020 - link

    I'm not sure there really is a chipset. It could be running USB and SATA straight from the I/O die. Just needs a simple system controller chip so that it can boot.
  • Spunjji - Wednesday, July 15, 2020 - link

    I think the "chipset" provides RAS features as well, though I'm not certain on that front.
  • appleache - Tuesday, July 14, 2020 - link

    The main reason for oem only is probably that they can’t get motherboard maker to make another line trx40 just with 8 channels wiring. The potential market is not big enough to justify the investment for launching a new product line, when trx40 is already enough for diy retail market. Hopefully asus & msi etc will come up with their own Tr pro machine and start to sell the compatible motherboard to cyberpower etc.
  • brucethemoose - Tuesday, July 14, 2020 - link

    Thats awfully close to Milan, isn't? Unless Vermeer is (suprisingly) coming first, or "Zen 3 2020" is more of a Dec 31 paper launch.
  • psyclist80 - Tuesday, July 14, 2020 - link

    From what ive heard, Vermeer IS first this time 'round. Probably to hit that 2020 time frame, as validation takes less time on the consumer lineup. I suspect Sept 7 announce, with shipping ~1 month later.

    I believe that Threadripper processors in PRO version or soon for enthusiasts for 2 processor boards will be created !!! That would be something amazing. First, it would be a decent competition for the powerful dual processor graphics workstations / workstations from DELL, HP, etc., which were doomed to Xeon processors. (EPYC have too low clock to work comfortably, smoothly on them in advanced simulation applications, special effects in movies, heavy animation scenes. Where you need a still strong one thread) And secondly it would be a great treat for enthusiasts who have a second time in computer history they could build extremely powerful computers with 2 high-clocked processors with a large number of cores, an unlimited amount of RAM with huge transfers, and the possibility of OC, computers exceeding all limits. Imagine a computer for work / home consisting of 2 x Threadripper 4995X 7nm +, ZEN3, 64-80 Cores, 3.4Ghz base, 4.5Ghz boost, 1TB fast 8 channel RAM, transfers from and to RAM exceeding 250GB / s, access times below 60ns . + Ampere / RDNA2 .. Such a computer would have more power than the fastest supercomputer from 2000 ASCI White! from CPU power alone! (Adding the power of RDNA2 or Ampere would probably beat the supercomputers from the next 1-3 years ... including Earth Simulator from 2002). The fun would be similar to the legendary platform for enthusiasts - EVGA SRX-2 + 2 Xeons 6 core with HT + OC to over 4Ghz .. Since then for several years it was not possible to build such monsters in the basement. And still such processors would not be a competition for EPYC (typical working mules for 24H work in large data centers and supercomputers)
    I think it would not be a problem for AMD to spend even TR3 with the paired function taken directly from EPYC since the CPU sockets are so similar.

    I count on the TRX80 enthusiast chipset that AMD mentioned in 2019!
  • Mr Perfect - Wednesday, July 15, 2020 - link

    This Threadripper Pro line would be perfect if it wasn't locked away behind the OEMs. In the past you could get low core count Threadrippers if you wanted lots of memory and IO, but didn't need a lot of cores. Why did that option disappear?
  • guyr - Friday, July 31, 2020 - link

    AMD is not Intel - they don't have the resources to make hundreds of variations of the CPUs they offer. So, they need to settle on a small number of configurations they believe they can sell in enough volume to make money. I had my eye on the 2950X; I worked in software development (now retired) and 16 cores was the sweet spot. I held out for the 3000 series for improved performance, so I'm likewise disappointed to see the 16-core part disappear (migrated down to the AM4 platform.) But I understand AMD's limitations. So, if I really want this, I'll have to move up to the 24-core part.
