Right, so different boards, ssd chips, ram generations, even the displays make a difference since newer panels are more efficient on average. Absolutely inexcusable.

Btw among the W10 devices they even put an Intel “Y”, a cpu with 3.5-7W TDP 😂. I have one of those and it’s the worse computer I ever used, recently revived with CachyOS because thankfully it has the x86v3 instructions (=it’s not too old)
