AMD Threadripper Pro Workstation CPUs and WRX80 Motherboards Officially Released for the DIY Market


If anyone needs a 64-core, 128-thread processor for a workstation task, AMD has announced that its Threadripper Pro desktop processors and WRX80 motherboards are now available to buy in the DIY segment.

AMD Threadripper PRO CPUs and WRX80 motherboards feature 8-channel DDR4 ECC memory and support up to 2TB and 128 PCIe Gen 4 lanes

The AMD Threadripper PRO series advances in all categories and outperforms the competition in most areas. It has 128 PCIe Gen 4.0 lanes which is double compared to the normal Threadripper series in 64 PCIe Gen 4.0 lanes. The most delightful feature for most is the 8-channel ECC support with a maximum capacity of 2TB (UDIMM, RDIMM, LRDIMM). The TDP for all four processors is set at 280W.

To take advantage of Threadripper PRO, you must also purchase a WRX80 motherboard. So far, ASUS, Gigabyte, and Supermicro have made their options available. Motherboards have ridiculous amounts of I / O and connectivity. Each motherboard has 7 PCIe Gen 4.0 slots and has a wide variety of connectors. The Threadripper PRO series can support up to 2TB of DDR4 memory, but the motherboard is the limitation as all 3 models only support 1TB of DDR4 memory. Don’t get me wrong, 1TB is a lot, but for the ultimate workstation, that extra terabyte could make a big difference.

The price seen in the table shows us that AMD Threadripper PRO 3995WX will cost $ 5,489, Threadripper PRO 3975WX will cost $ 2,749 and Threadripper PRO 3955WX will cost $ 1,149. The Threadripper PRO 3945WX is priceless yet. If you want to learn more about the Threadripper PRO series and WRX80 motherboards, read this article that covers the details.

Motherboards with AMD WRX80 chipset from SuperO, ASUS and Gigabyte

AMD’s workstation partners, which include Supermicro, ASUS, and Gigabyte, have also announced their respective WRX80 motherboards that consumers can purchase. These motherboards are the ultimate workstation solution, offering incredible amounts of I / O and connectivity. Let’s start with the specs and in-depth details of these motherboards.

ASUS WRX80 PRO WS SAGE SE motherboard

AMD Radeon RX 6700 XT Custom and Reference Models Launching March 17, Announced Today

The ASUS WRX80 PRO WS SAGE SE features the huge SP3 socket that houses 4096 LGA pins and only supports AMD’s Ryzen Threadripper Pro series processors. Surrounding the socket are eight DIMM slots that can support up to 1 TB of DDR4 memory with speeds up to 3200 MHz RDIMM / LDIMM. Some notable motherboard features include:

  • AMD sWRX8 socket: Ready for AMD Ryzen Threadripper PRO Series processors
  • Lightning-fast connectivity: USB 3.2 Gen 2×2 Type-C port, 10 USB 3.2 Gen 2 ports, 3 x M.2 PCIe 4.0, HYPER M.2 x16 Gen 4 card and Inte® X550-AT2 dual 10Gb Ethernet
  • ASMB9-iKVM remote management: BMC chip to provide intelligence for your IPMI architecture for out-of-band management to enhance hardware-level control to improve IT efficiency
  • Powerful performance: 16 power stages, multiple GPU support, and R-DIMM memory support
  • Reliable stability: Tested for 24/7 reliability, validated for robust compatibility, and equipped with SafeSlot for maximum security

Unlike Gigabyte, ASUS has made use of larger aluminum heat sinks that cover the power supply system. The M.2 slots are also covered by full-length heat sinks, while the PCH features active fan cooling. The mesh plate above the PCH heatsink looks great and you can see the location of the fan underneath. There is also a similar mesh plate above the heatsink next to the rear panel I / O. You can also see an active fan cooling solution implemented here and the mesh grille hides it perfectly and doesn’t interfere with airflow either.

As for power, the ASUS WRX80 PRO motherboard features three standard 24-pin 8-pin ATX connectors and also carries two 6-pin auxiliary plugs to power the PCIe lanes. The motherboard has a total of 7 PCIe 4 slots, all full length and all complemented by metal shielding around it. Storage options come in the form of 8 SATA III ports, two U.2 ports, and two M.2 slots. There is an impressive variety of I / O on the motherboard. Internally only, we can see various USB 3.2 and USB 3.0 headers on the front panel. The motherboard also has on / off and reset buttons along with a high-end audio subsystem on its own isolated PCB area. The motherboard will be priced around $ 850-999.

Gigabyte WRX80 SU8 motherboard

The Gigabyte WRX80 SU8 is not just an ordinary design and that is evident in its CEB form factor. The SP3 socket on the motherboard is inverted horizontally instead of the traditional vertical position. The board has a 10 + 3 phase power design, one that is powered by dual 8-pin connectors and a 24-pin ATX connector. There are four DDR4 DIMM channels on each side of the socket, and the board is listed to support 8-channel DDR4 memory with capacities up to 1TB. The maximum speeds supported by the board are 3200 MHz (RDIMM / LDIMM).

Both the WRX80 chipset, the VRMs, and the 10G Ethernet controller are cooled by their own set of heatsinks. The WRX80 chipset is also equipped with an active cooling solution. Onboard expansion includes a total of 7 PCIe 4.0 x16 slots, all of which should run on the x16 link, as AMD Threadripper Pro CPUs offer up to 128 PCIe Gen 4 lanes.

There are also four SATA ports and two M.2 ports. The internal USB ports include four front panel USB 3.1 headers. As for the rear I / O, the motherboard carries two 10GbE and two 1GbE LAN ports, a range of USB 3.1 Gen 2 ports, DisplayPort / VGA / DVI outputs, and a 7.1 channel audio gimmick with technology. AMP-UP audio input. The board will support AMD Threadripper Pro CPUs with up to 64 cores and 280W TDP, such as the 3995WX. Plus, you’ll also find some great accessories with the board, like a Thunderbolt add-in card and an M.2 expansion card. There is no word on the price or release date of the Gigabyte WRX80 SU8 motherboard, but we expect it on the market in early 2021.

Supermicro SuperO M12SWA-TF WRX80 motherboard

The Supermicro SuperO M12SWA-TF is another WRX80 motherboard that comes with the CEB form factor. The motherboard features the SP3 socket and eight DDR4 DIMM slots that can support up to 1TB of DDR4 memory. The motherboard carries an 18-phase power delivery and features dual 8-pin connectors for booting.

Expansion slots include a total of six PCIe Gen 4.0 x16 slots, four full-length M.2 (Gen 4.0) slots, and storage options include four SATA III ports and two U.2 ports. The motherboard has an active fan solution on top of the WRX80 chipset. The motherboard can support 2 triple-wide, 4 double-wide and 6 standard graphics cards. Onboard I / O includes a 10Gb Aquantia LAN, 1GB Intel LAN, 1 USB 3.2 Gen 2×2, 5 USB 3.2 Gen 2, 5 USB 3.2 Gen 1, and 2 USB 2.0 ports. Additional connectors include up to 10 4-pin fan headers, a Realtek ALC4050H + ALC1220 7.1 channel HD audio connector.
