>Now Intel tries to get a cut of the market, but they are too late.
It's really more complex then that.
x86_64 has a lot of backwards compatibility. Even low power chips made by Intel typically consume 2-5x the wattage of ARM counter parts. Intel's very low power line (matches ARM) doesn't actually have the 64bit extension and is functionally a i586 chip from circa 1999-2003. Modern x86_64 chips have a whole section of die space dedicated to emulation, re-ordering, re-naming, and caching for us to pretend x86 is fast.
Then you have monopoly. Intel is the only company making x86_64 chips (Yes VIA/AMD exist, but collectively they have <10% of the market). They are the only show in town, it's their prices. While ARM simply licenses it's IP to other companies, who then compete with one another and drive prices even lower.
