Apple Motion with the New Metal Engine Supercharges RAM Preview

October 19th, 2019 by rob-ART morgan, mad scientist

Apple released Motion 5.4.4 with a new Metal Engine. We used the Atmospheric-Open sample project to measure the performance gain compared to Motion 5.4.3.


GRAPH LEGEND

Radeon RX 580x2 = 2010 Mac Pro 12-core with two Radeon RX 580 GPUs
Radeon RX 580 = 2010 Mac Pro 12-core with one Radeon RX 580 GPU
FirePro D700x2 = 2013 Mac Pro 8-core with two internal FirePro D700 GPUs
Radeon Pro Vega 64 = 2017 iMac Pro 8-core with internal Radeon Pro Vega 64 GPU

Radeon VII = 2013 Mac Pro 8-core with one external Radeon VII in eGPU
or 2017 iMac Pro 8-core with one external Radeon VII in eGPU

TEST PROCEDURE: Used a stopwatch to time how long it took to render RAM Preview of Atmospheric-Open sample 600 frame project. (macOS Mojave was used on the three Pro Macs.)

WHAT DID WE LEARN?

The classic 2010 Mac Pro tower with either one or two Radeon RX 580s recorded a significant drop in time it took to render the RAM Preview using the newest version of Motion. In this case, Motion automatically used dual matching RX 580s when rendering.

The 2013 Mac Pro cylinder's dual FirePro D700s surprisingly beat the Radeon VII in an eGPU box. That's partly due to the fact that Motion automatically used both matching D700s when rendering. However, when we added two Radeon VIIs in eGPUs, it only used one to render.

The 2017 iMac Pro's internal Pro Vega 64 was faster than the external Radeon VII. There is no option in Preferences or Get Info to force Motion to use both GPUs. Even when we mounted two Radeon VIIs in eGPU boxes, Motion stubbornly used only one.

As highlighted by the RED bars, in all cases, Motion 5.4.4 with the new Metal Engine significantly reduced the time it took to render the RAM Preview compared to Motion 5.4.3.
