You have been listening to propaganda. ARM has always been better. Consider the fact that it still exists, despite Intel's predatory nature. It exists because Intel could not make a processor for the low power market that was performant. They tried. But anything they built either took too much power, or used the right amount of power but was too slow. So ARM survived in this niche. But it couldn't grow out of this niche because Intel dominates ruthlessly.

But the low power market shows that, for a given power consumption, the ARM is faster. Does that not apply everywhere? Yes, it does. And so Apple, which controls its own destiny, developed an ARM chip for laptops and desktops. Its faster and cooler and cheaper than Intel chips, because ARM has always been faster and cooler and cheaper than Intel chips.

AWS, which also controls its own destiny has launched Graviton2. These are servers which are faster and cooler and cheaper than Intel servers, and the savings and performance are passed on to customers.

As long as Intel ruled by network effects - buy an Intel because everyone has one - build an Intel because it has the most software - their lack of value didn't matter.

There are now significant players who can ignore the network effects. The results are so stunning that many people simply refuse to believe the evidence.
