What just happened? Lenovo has unveiled a workstation that boasts an impressive feature: it’s the world’s first, and only, professional workstation powered by the new Threadripper Pro chip. The CPU offers a massive 64 cores/128 threads and can boost to 4.0 GHz. It also comes with 8-channel memory support, allowing buyers to add up to 1 TB of DDR4.

AMD is using the ThinkStation P620 to reveal its new 3995WX processor, which is the first Threadripper to carry the Pro branding. The workstation is based on the BXB-B chipset, offering PCIe Gen 4 support and 128 PCIe lanes.

AMD’s Pro line comes with a number of features, most of which are focused on security. These include Memory Guard for real-time encryption of system memory, an on-chip security processor, Secure Boot, and TPM 2.0.

The 3995WX is the flagship in the Threadripper Pro line. It features a 2.7 GHz base/4.2 GHz boost, 288MB total cache, and a 280W TDP.

Lenovo notes that this is currently the only PCIe 4.0 workstation and is positioning it as a cost-effective alternative to dual-socket systems such as its P720 machines. Storage-wise, it can be specced with up to 4TB of M.2 PCIe SSD and up to 16TB of 3.5-inch SATA 7,200rpm drives.

Graphics are provided by up to two Nvidia Quadro RTX 8000 or four Quadro RTX 4000 cards, allowing support for multiple simultaneous displays. There’s plenty of connectivity, too, with four USB 3.2 Gen 2 Type-A ports, two USB 2.0 ports, two PS/2, 10-gigabit Ethernet, and several audio ports on the rear. At the front, there’s pair of USB 3.2 Gen 2 Type-A ports, two USB 3.2 Gen 2 Type-C ports, and a 3.5mm jack.

Not surprisingly, all this power comes at a cost. The ThinkStation P620 will start at $4,599 when it launches in September.

I really hope AMD gets something in return for this exclusivity - unlike what they got from Alienware / Dell for TR exclusivity.

Starts at $4,599.... since the “normal” 3990x costs $4,000, I’ll assume that the workstation doesn’t default to 64 cores... the starter version must have a 3960 or 3970...

Wonder how much a “maxed out” version costs...

The slide detailing the TR Pro states that there are 12/16/32/64 core variants all with 8-channel RAM.

Given what the slide says, I'll speculate that for that price, it is a 12-core variant of the TR Pro - maybe 39xxWX where the xx is the 12-core variant.

12 and 16 cores... I guess they've just rebranded the 3900 and 3950 as low end Threadripper Pro... And added PCI lanes for the high end ones...

It sounds like they also added the 8-channel RAM. A wider ram bus comes in handy for some workloads like FEA and other types of workloads, I am sure.

To double the number of memory channels and PCI Express lanes would require the IO chip from the EPYC range (or a completely new one just for the Threadripper Pro models, although this is unlikely), so it can't be a simple rebrand.

Yeah.... looking at it a little more carefully, it seems they’ve just rebranded EPYC chips... that would explain all the improvements over “regular” threadripper.
Makes sense, since it’s for workstations anyways...

Ohhh... I do like that... wonder when it will be available to purchase on it’s own for custom builds...
According to Anand, the entire platform is going to be OEM only. It also requires the WRX80 chipset and the TRX80 socket. I expect that means that if it ever is available retail, the MB would be more expensive than the regular TR line.
We will see what happens, though. OEM CPUs used to make it into the market a while back.
