Very rare reference AMD model with just 2x 8-pin PCIe power connectors.

 

The fastest ever possible graphics card for Mac Pro 4,1/5,1 exclusively from MacVidCards Europe. Features the latest Navi21 chip from the RDNA2 family and insane 16 GB of GDDR6 memory.

 

Native EFI boot screen. You no longer need any software patches to see boot picker or boot screen. Patcher is only need for macOS installation.

 

Only our modified cards are able to work normally in these models. Standard PC cards won't even boot inside Mac Pro.

HDMI/DisplayPort Audio support under macOS and Windows out of the box. No patches needed.

 

Metal performance:

- 127% faster than the previous generation RX 5700 XT

- 188% faster than Vega 56

- 232% faster than RX 580
