BARE FEATS LAB - real world Mac speed tests

RX 6900 XT GPU versus Pro Vega II Duo in the 2019 Mac Pro

June 24th, 2021 by rob-ART morgan, mad scientist


How does the Pro Vega II Duo compare to a single RX 6900 XT? And how fast do they run when BOTH are active?

GRAPH LEGEND

6900 XT + Vega II Duo = AMD Radeon RX 6900 XT and Apple Pro Vega II Duo
Pro Vega II Duo = Apple Pro Vega II Duo
RX 6900 XT = AMD Radeon RX 6900 XT
Pro Vega II = Apple Pro Vega II

Testing Platform: 2019 Mac Pro, 3.3GHz 12-Core Xeon W CPU, 96GB RAM, macOS Big Sur 11.5 Beta

Octane X - Metal
Render Benchmark Trench. (LOWER time in Seconds = FASTER)

AMD RX 6900 XT and 2019 Mac Pro

DaVinci Resolve 17 - Metal
Playback the Candle 1080p project using triple noise reduction. (HIGHER Frames per Second = FASTER)

AMD RX 6900 XT and 2019 Mac Pro

WHAT DID WE LEARN?

When both the AMD RX 6900 XT and Apple Pro Vega II Duo were active, they produced the fastest times for both Octane X and DaVinci Resolve. But when running separately, the RX 6900 XT ran DaVinci noise reduction fastest while the Vega II Duo ran Octane X render fastest.

NOTE: The AMD Radeon RX 6000 Series requires Big Sur 11.4 or later when running on a Mac.

Since the RX 6000 Series has three Display ports, you will want to use a display that has DisplayPort 1.4 with DSC. We tested using a Dell UP2715K display which has dual DisplayPorts to enable support of 5K.
