Brand new card, flashed for Mac by MacVidCards! Very rare reference Biostar model with just 2x 8-pin PCIe power connectors.
Another fastest ever graphics card for Mac Pro 3,1/4,1/5,1 exclusively from MacVidCards Europe. Even faster than standard Radeon RX 6800 with much bigger copper heatsink. Features the latest Navi21 chip from the RDNA2 family and insane 16 GB of GDDR6 memory.
Card has 2,2-slot wide cooling, so will block nearby PCIe slot for most of other PCIe cards, but it's still possible to install very slim PCIe cards like NVMe controllers or USB 3.0 expansion cards next to it.
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.
Supports macOS Big Sur 11.4 or later and macOS Monterery 12.0.1 or later (12.2.1 recommended). Also supports Windows 10/11 in UEFI and legacy mode.
HDMI/DisplayPort Audio support under macOS out of the box. No patches needed.
Metal performance:
- 22% faster than RX 6800
- 122% faster than the previous generation RX 5700 XT
- 181% faster than Vega 56
- 224% faster than RX 580
Requires extra SATA power from one of the HDD bays (or optical bay) or Pixlas mod. See installation manual. Comes with SATA power cables kit.
Card is 2,5-slot wide so it will block nearby PCIe slot inside Mac Pro.
