Google Cloud Tau T2A Ampere Altra vs. T2D AMD EPYC Performance

Over the summer Google announced Tau T2A as the first Google Cloud Compute Engine VM to run on Arm. The T2A series is powered by Ampere Altra processors and complement the Tau T2D series powered by AMD EPYC 7003 "Milan" processors that launched last year. I have been trying out the Tau T2A series for the past several weeks and have some initial benchmarks to share today for showing how the Ampere Altra Arm VMs can perform against the existing T2D series.
