5090 was an example, same process applies to lower tier GPUs that don't require extra power cables. ie a 3080 with the same power budget as a 1080 would run circles around it (1080 with default max power limit of 180w gets approx 7000 in TimeSpy, 3090 limited to 150w gets approx 11500). Limiting the power budget is very simple with tools such as MSI Afterburner and others in the same space.
