Use the Radeon Pro W5700X MPX Module with your Mac Pro

Learn about the different display set-ups that you can use with your MPX Module on your Mac Pro (2019).

The Radeon Pro W5700X MPX Module contains an AMD Radeon Pro W5700X graphics processing unit (GPU) with 16 GB of GDDR6 memory, four Thunderbolt 3 ports and one HDMI 2.0 port. You can use the Thunderbolt 3 ports to connect displays and external devices to your Mac Pro. When you use the Radeon Pro W5700X MPX Module with your Mac Pro, you can also use the Thunderbolt 3 ports on the top* and rear of your Mac Pro to connect additional displays.

If you use Boot Camp and have already set up Windows, install AMD drivers before installing the Radeon Pro W5700X MPX Module.

About ports and buses

The MPX module has two buses for its Thunderbolt 3 ports. If you connect two 5K or 6K displays to the Thunderbolt 3 ports on your MPX module, connect one display per bus.

If you connect a display to the HDMI port on your MPX module, the Thunderbolt 3 ports on Bus 0 can support one additional display with a resolution of 4K or lower. If you need audio output from a display connected to the HDMI port and have other displays connected over Thunderbolt 3, don't connect a display to the Thunderbolt 3 port next to the HDMI port.


Connect displays to a single Radeon Pro W5700X MPX Module

If you install a single Radeon Pro W5700X MPX Module, you can connect up to six displays using Thunderbolt 3 in these configurations:

  • Three Apple Pro Display XDRs with resolutions of 6016 x 3384 at 60Hz connected to any three of the following locations: Bus 0, Bus 1 and either the top* or rear Thunderbolt 3 ports on your Mac Pro. Connect one display for each location.

Use the Radeon Pro W5700X MPX Module with Microsoft Windows

If you use Boot Camp and it's already set up on your Mac, install AMD drivers first before you install the Radeon Pro W5700X MPX Module:

  1. Start up your Mac in Windows.
  2. Go to the AMD website, then click Drivers & Support.
  3. Select your product from the list, not the menu: First select Graphics, select Mac Graphics in the next column, then select Apple Boot Camp in the next column.
  4. Click Submit to view the list of available drivers.
  5. Look for the driver version that supports your Mac model, then click Download.
  6. Extract the downloaded ZIP file, then run the Setup app in the resulting folder to install the drivers.
  7. Shut down your Mac, then install the Radeon Pro W5700X MPX Module.

If you didn't install AMD drivers and your display shows a black screen, connect your display via HDMI, then follow the steps above. After you install the AMD drivers, you can connect your display via Thunderbolt 3.
