Comparison of Performance of Multiple CPU Architectures

With an increase in the choices of CPU architectures available both on-premise and in the public cloud, it is becoming increasingly important to understand the differences in performance between these options.  We will compare performance examples of 4 different CPU vendors while also comparing bare metal and two public cloud enviroments.  Our testing will utilize SPECjbb2015 with OpenJDK17 to illustrate various aspects of peak throughput as well as latency response.  We'll also consider performance/watt differences measured on bare metal workloads, providing further insight into different architectures.  Rather than attempting to declare a "winner", we'll focus on illustrating similiarites and differences among multiple high performing architectures.
