AmpereOne® processors are designed from the ground up to deliver exceptional performance for Cloud Native applications. With an innovative architecture that delivers high performance, linear scalability, and stellar energy efficiency, AmpereOne® enables applications like PostgreSQL to run in a predictable manner, with minimal variance under increasing loads.

Oracle Cloud offers the cost-optimized A2 VMs powered by AmpereOne® processors in multiple flexible VM shapes – up to 78 OCPUs (156 cores) per VM, 946GB total memory, up to 78 Gbps networking bandwidth, and a wide range of network-attached storage options. These VMs are suitable for scale-out Cloud Native workloads like web servers, in-memory caches, databases, containerized microservices, data-logging, media transcoding, and Big Data applications.

In this performance brief, we compare PostgreSQL running on Oracle Cloud A2 VMs powered by AmpereOne® processors to AMD EPYC™ Genoa-based E5 VMs while measuring throughput on each of these instances.

The relative performance data is shown in Fig1. The A2 VM has a performance advantage of 4% over the E5 VMs.

As figure 2 shows, the price-performance of the AmpereOne A2 VM is 1.6X of the AMD E5 VM. The instance pricing is derived from the Oracle Cloud cost estimator tool: https://www.oracle.com/cloud/costestimator.html

PostgreSQL 13.1 was used for the tests with HammerDB 4.3 as the load testing software. The A2 and E5 systems under test (SUT) were 16 OCPU VMs. Three runs were performed to ensure run-to-run variance was low.

Oracle Cloud A2 instances with AmpereOne® processors provide high performance for database solutions like Postgres. The 4% performance advantage on the A2 VMs combined with the 60% price-performance advantage makes PostgreSQL deployments on the AmpereOne-based Oracle Cloud A2 VMs compelling.
