From your link: "Even under demanding multi-threaded workloads, the M2 MacBook Air was not nearly as warm as the other laptops tested"

Keep in mind the 6850U you're comparing against has a fan too. Notebookcheck says it has a 40W turbo on the gen 2 model, and the gen 3 Intel version has a 28W sustained boost. An M2 uses around 20W.

Also, a lot of those benchmarks are showing all x86 CPUs with a 3x+ lead, which indicates software optimization problems. Geekbench 5 is optimized for both arm64 and x86 and shows the M2 ahead of the 6800U. There are also just broken results like the LC0 test where the M1 is substantially faster than the M2. Overall, your results don't seem very valid.
