Amazon Graviton3 vs. Intel Xeon vs. AMD EPYC Performance

The Rodinias OpenMP benchmarks easily were the fastest with Graviton3 thanks to being backed by sixteen physical CPU cores. It's also amazing to see how far Graviton has come since the original a1.4xlarge instance type.

Similarly, Graviton3 was much faster than Xeon/EPYC instances for the AMG HPC benchmark.

The AMD EPYC Milan instance still led with the MrBayes molecular biology workload as well as for the performance-per-dollar.

Overall the Graviton3 had a great showing when comparing these "4xlarge" instances.
