The A1 instances remain terribly slow with the Python performance in benchmarks like PyBench while the Intel instances were leading with this single-threaded benchmark.

Those wishing to dig through more benchmark data of these different instance types can find all the numbers via this OpenBenchmarking.org result file.

If wanting to see how your own bare metal hardware or VMs compare to these different Intel / AMD / Graviton 2xlarge/4xlarge instance types, simply install the Phoronix Test Suite and run phoronix-test-suite benchmark 1903298-HV-AMAZONEC210 to facilitate your own side-by-side benchmark comparison. Set the COST_PERF_PER_HOUR= environment variable if wanting to run a cost analysis as well.
