While Graviton is impressive and probably an indication of things to come, you can't outright use "Amazon rents them cheaper to me" as an indication of the price performance of the chips themselves.
Amazon is exactly the kind of company that would take 50% margin on their x86 servers and 0% margin on their Graviton servers in order to engineer a long term shift that's in their favor - the end of x86 server duopoly (or monopoly depending on how the wind is blowing).
