I’ve done Coremark scores across a range of different systems including NUCs and Pi’s. A Pi 4 gets a single thread score of about 10k and a new entry level NUC gets about 20k. If you look at older systems a Beelink T4 Pro Mini (using a much older CPU) gets about 11k well within the same ballpark as a Pi4. Comparing that to a similar aged Pi a Pi3B gets about 4k score. For comparison a high end AMD Ryzen gets about 45K.
