PostgreSQL is a powerful, open-source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads. PostgreSQL has a reputation of proven architecture, reliability, data integrity, robust feature set, extensibility, and the dedication of the open-source community behind the software to consistently deliver performant and innovative solutions.

Figure 1 shows the energy efficiency of the three processors running PostgreSQL. The AmpereOne® A192-32X had a 39% better performance/watt compared to the AMD EPYC 9654, and 7% better than the AMD EPYC 9754.

PostgreSQL 13.1 was used for the tests with HammerDB 4.3 as the load generator. The test used is HammerDB’s TPCC-like OLTP test. The TPCC like workload causes each user to execute a combination of 5 different procedures on the DB: New Order, Payment, Delivery, Order-status, Stock-level. We scale the number of users such that the system is fully utilized to achieve maximum new orders per minute (NOPM). NOPM is the measured metric on the system under test.

AmpereOne® processors provide high performance for database solutions like Postgres. The performance AmpereOne processors combined with the 39% perf/watt advantage makes PostgreSQL deployments on the AmpereOne processors compelling.
