From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I did a quick Google.

Is the best actual test data I can find. It uses a physical power meter, so it's full system (not TDP or self reporting power consumption).
And it's a few years out of date.
Seems like Apple silicon is the winner (and will probably continue to be).
The Xeon that beats the rpi4 for GFLOPS/watt is an e5v3, which was launched in 2013 and EOL in 2021.
So there will absolutely be some new Xeon CPUs that will perform better.
However, for a $50 device, it's probably the best GFLOPS/watt/$ from what little empirical data I can find
