Whatever. Just use high performance power plan if you'll do it. Here's the savefile, just do a capframex recording driving straight from the starting point for 50-60 sec. RT ultra preset (no path tracing), 720p/1080p+DLSS or whatever that makes it CPU bound. Maybe 2-3 runs to see the consistency if you don't mind bothering.
Here you go, hope it helps:
