No you're not wrong, if you're comparing ARM CPUs on Linux to one specific Intel CPU, the Lunar Lake V ones. Then yeah you're not wrong, it's very much a case of optimisation for CPUs like the Snapdragon X Elite CPUs in comparison.

But if you widened the scope a bit more, then I think there's plenty of more energy hungry x86_64 CPUs compared to ARM.
