The Raspberry Pi 5 results on Geekbench 6 are all over the place. A score between 500 to 900 in single core and a 2000 multi core score.
Radxa 4 is an SBC based around the N100 and it basically gets the same or slightly higher performance as the Raspberry Pi 5.
Meanwhile the i5-9600K gets a score of 1677 in single core, which is 83% of the performance of the entire Raspberry Pi 5 and gets a score of 6199 when using multiple cores, that's 3x the performance.
I'd call this at least "Laptop class" and you even admitted yourself back in 2025 that you're using a processor on that level.
