Gamers nexus kind of does that https://www.youtube.com/watch?v=nRaJXZMOMPU&t=704s https://www.youtube.com/watch?v=nRaJXZMOMPU&t=704s Basically how many watts required to do some fix unit of work (to render 1 frame using Blender CPU rendering)

Your cpu can simulate the universe at 1W. Although it will take a long time.

  My CPU can't, but it is theoretically possible to make a CPU that could.

    do you mean that a turing machine can't simulate the universe but some other kind of cpu (i.e. quantum) could?
    - jhoechtl 4y ago
      This is all very theoretical so ... a turing machine can simulate a universe as it assumes infinite memory

      No, I mean that it is physically possible to perform an unlimited amount of computation on a fixed amount of energy, if you are willing to wait long enough. Nobody has built hardware that has this property.

        1W is one joule per second. With unlimited time, you also have unlimited joules trickling out.

        You are not getting this. 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.

That is a useful measurement, but it's not quite what I'd want. 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.
