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 out of the box. No patches needed.

- 101% faster than RX 5500 XT


Works on internal power using just a single 8-pin connector. It has a very low TDP of just 132W.


Card is just 2-slot wide so won't block nearby PCIe slot inside Mac Pro!
