Benchmarking Amazon's ARM Graviton CPU With EC2's A1 Instances: Monday night Amazon announced the new "A1" instance type for the Elastic Compute Cloud (EC2) that is powered by their own "Graviton" ARMv8 processors. Since then I have been running benchmarks on Amazon's first-generation 64-bit ARM processors and seeing how these ARM cloud instances compare to their Intel Xeon and AMD EPYC performance on EC2 in both raw performance as well as performance-per-dollar.
