Here's some x86 vs arm comparisons from 2020 substantiating "20% faster and 20% cheaper" -- https://www.honeycomb.io/blog/observations-on-arm64-awss-ama...

AWS isn't offering steep discounts IMO, they're reflecting the true cost to run the processors in terms of cost of licencing the processor IP and the cost of the power/cooling the processors require. I suspect they are getting better margins on the Graviton line than on the conventional Intel/AMD chips even after giving the relative price discount.
