Reversed GPU order Mojave vs Catalina?

When encoding a video or else in my iMac 2017 Mojave 10.14.6 with BMD eGPU Pro, I could see the Radeon Pro 580 maxing out on the graph of GPU history in Activity Monitor, and the external RX Vega 56 not maxing out or rarely maxing out.

Now, with my new iMAC 2020 Catalina 10.15.7, it's the other way around. The eGPU gets maxed out but not the Radeon Pro 5700XT.

Why? Is it just a misinterpretation on my part? Is it normal?

Since the Radeon Pro 5700 XT is the latest, greatest and fastest GPU (right?), I would prefer it being maxed out and then the eGPU.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
