I used sbc-bench, a nice benchmark for small boards, focusing on memory and cpu. sbc result details: raspi4/raspbian raspi4/Fedora32-raspbian64bit-kernel nintendo switch
percentages: this assumes the Thinkpad values as 100%, and computes the other values on base of that.
RAM size is not important for the tests which were performed, less than 2GB were used.
sbc execution:

wget https://raw.githubusercontent.com/ThomasKaiser/sbc-bench/master/sbc-bench.sh
sudo /bin/bash ./sbc-bench.sh -c

power: need a usb-c power meter for that
- then compute how much electrical power is required for certain operations.
GPU:
- would be especially interesting to also compare various 3D driver implementations. For example, 3D benchmarks running on horizon (Nintendos OS) and also on Linux/switch.
- It's hard to only measure the GPU. It's also a question of how good the 3D drivers are.
- Benchmarks should include retro game emulation. Simply because it's a common use case for pi4 and switch/Linux. bsnes and snes9x?
  - free snes rom?
