Major GPU Performance Upgrade for Your 2019 Mac Pro
If you purchased a Mac Pro® with the standard AMD Radeon Pro 580X, Vega II, W5500X or W5700X MPX module, then adding the AMD Radeon RX 6900 XT graphics card can deliver a significant graphics productivity boost. Whether you’re editing, rendering, color correcting video, or creating VFX or 3D models, the AMD GPU card’s latest graphics architecture enables greater performance!
Combine GPU Muscle Power
You can even combine the power of your Mac Pro’s existing GPU with the 6900 XT—many task times on supported applications can be slashed when two GPU cards are employed. Installing the Radeon RX 6900 XT can multiply your computer’s graphics processing power, enabling it to handle 4K, 5K, 6K, and 8K workflows more efficiently.
Supports Pro Display XDR
The Apple® Pro Display XDR delivers stunning color, dynamic range and clarity—it’s ideal for professional workflows. What it doesn’t have is DisplayPort or HDMI ports. With the AMD Radeon RX 6900 XT from Sonnet, that’s not a problem. This GPU includes a USB-C port that connects to the Pro Display XDR,(1) enabling you to take advantage of the most advanced Apple display ever.
