Use the Radeon Pro Vega II Duo MPX Module with your Mac Pro

Learn about the many different display setups you can use with your MPX Module on your Mac Pro (2019).

The Radeon Pro Vega II Duo MPX Module contains two AMD Radeon Pro Vega II Duo graphics processing units (GPUs) each with 32GB of HBM2 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 Vega II Duo 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 install a third-party graphics card from AMD, you may need to use different AMD drivers in Windows.

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 to output audio to 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.

You can connect up to eight displays using Thunderbolt 3 in these configurations:
