AMD today announced that the Ryzen Threadripper PRO workstation processors will be directly available for purchase from March 2021. Until now, the processors were exclusively available as options for the Lenovo ThinkStation P620 workstation. The processors are being released alongside a small selection of compatible motherboards by ASUS and GIGABYTE. The Threadripper PRO processors are built in the sWRX8 package, and compatible with the AMD WRX80 chipset. From what we can tell, these processors are not compatible with sTRX4 motherboards.

What sets the Ryzen Threadripper PRO apart from the regular Ryzen Threadripper 3000 series is that it's a fully unlocked "Rome" multi-chip module re-configured for the workstation, with up to 64 CPU cores, 8-channel DDR4 memory, and 128 PCI-Express Gen 4 lanes. In comparison, the Ryzen Threadripper 3000 chips only feature 4-channel memory, and fewer 72 PCIe Gen 4 lanes from the SoC. The PIB (processor in box) retail package of the Ryzen Threadripper PRO looks rather plain compared to the PC enthusiast-focused Threadripper 3000, with a simple paperboard box that packs the processor, an Asetek AIO CLC adapter, and a spring-loaded screwdriver that's tuned for the sWRX80 socket.The Ryzen Threadripper PRO family includes four models, led by the flagship Threadripper PRO 3995WX, which is a 64-core/128-thread max-out of the "Rome" MCM, with a max boost frequency of 4.20 GHz. Next up, is the Threadripper PRO 3975WX, which is a 32-core/64-thread part, clocked up to 4.20 GHz boost. Following this, is the Threadripper PRO 3955WX, a 16-core/32-thread part clocked up to 4.30 GHz boost. Lastly, there's the Threadripper PRO 3945WX, a 12-core/24-thread part clocked up to 4.30 GHz boost. The 3955WX and 3945WX are particularly interesting parts, as AMD hasn't come up with 12-core or 16-core models of the regular Ryzen Threadripper 3000 series. All four chips are rated at 280 W TDP. AMD didn't mention pricing.
