RX 6900 XT GPU versus other GPUs in the 2019 Mac Pro
May 1st, 2021 by rob-ART morgan, mad scientist
We tested the AMD Radeon RX 6900 XT against the three best 2019 Mac Pro GPUs.
RX 6900 XT = AMD Radeon RX 6900 XT
Vega II = Apple Pro Vega II
VII = AMD Radeon VII
RX 5700 XT = AMD Radeon RX 5700 XT
Testing Platform: 2019 Mac Pro, 3.3GHz 12-Core Xeon W CPU, 96GB RAM, macOS Big Sur 11.4 Beta
BasemarkGPU - Metal
Official Test at 4K resolution and HIGH Content Quality. (HIGHER Frames per Second = FASTER)
Geekbench 5 - Metal
Metal GPU test. (HIGHER Frames per Second = FASTER)
GFXBench - Metal
Aztec High Tier OFFscreen. (HIGHER Frames per Second = FASTER)
Blender 2.90 - OpenCL
Using AMD's ProRender with BMW sample image. (LOWER time in Seconds = FASTER)
Octane X - Metal
Using Benchmark Trench. (LOWER time in Seconds = FASTER)
DaVinci Resolve 17 - Metal
Playback the Candle 1080p project using triple noise reduction. (HIGHER Frames per Second = FASTER)
TW: Warhammer II - Metal
Ran Skaven built-in benchmark at 3840x2160 High. (HIGHER Frames per Second = FASTER)
Shadow of Tomb Raider - Metal
Ran built-in benchmark at 3840x2160 High. (HIGHER Frames per Second = FASTER)
WHAT DID WE LEARN?
The AMD RX 6900 XT is a lot faster than the previous best GPUs for the 2019 Mac Pro. (Note that 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 support 5K.
We chose the Sapphire Nitro+ Radeon RX 6900 XT because it was 12.2 inches long. Versions longer than that will not fit in the 2019 Mac Pro.
