Understanding the capabilities of new architectures is key to informing system purchases and good long-term ROI for cluster installations. The newest AMD architecture, Milan, has become available first on Microsoft Azure and we use this opportunity to measure the performance of this 3rd generation AMD EPYC processor. In this paper single node performance is gathered for seven popular scientific applications and benchmark test-suites. Quantitative comparisons are carried out between two independent platforms, Milan and its architectural predecessor Rome, for performance evaluations. Our results have shown that the changes in the Milan architecture have improved performance and met our projections.
