Basically how many watts required to do some fix unit of work (to render 1 frame using Blender CPU rendering)

In that test, the CPUs are running on an open-air test bench with a 360mm AIO liquid cooler with the fans running at 100%. I don't think any of us are going to be running the CPUs like that, and that type of cooling encourages the CPUs to draw way more power - because they can draw much more power without overheating.
What I'd want in a test is to take some reasonable cooling solution (reasonable varies from person to person, of course) like a high-quality 140mm tower cooler or a 240mm AIO, in a computer case with the fans running at a silent or slightly above silent level. Then see what type of power and performance you get out of it.
You can do an unlimited amount of computation on one joule. One watt-second, if you like.
Not an infinite amount of computation, but any finite amount.
