Benchmarking Amazon's Graviton2 Performance With 64 Neoverse N1 Cores Against Intel Xeon, AMD EPYC

For those leveraging the Elastic Compute Cloud for build farm type purposes, Graviton2 m6g instances are a big improvement over the Graviton A1 instances, but still not to the speed of the AMD EPYC or Intel Xeon instances. The Xeon m5 instances had the leg up over the m5a EPYC instances, which is important to note are the older EPYC 7001 processors and not the newer EPYC 7002 Rome processors (Rome tests later in this article when comparing bare metal CPU potential).

Meanwhile with the 7-Zip compression test, the Graviton2 m6g CPUs perform extremely well and in fact were outperforming the similarly sized Intel Xeon and AMD EPYC instances. The 7-Zip performance was one of the tests with the biggest advantage for Graviton2 compared to the x86_64 instances.

Meanwhile with the PostgreSQL database server workload, the Graviton m6g instances were performing very well with similar (or better) performance to the older EPYC 7001 instances and Xeon instances. But there was an exception with the m6g.16xlarge instance strangely regressing across the multiple runs. But in any case overall m6g instances were surprisingly competitive for PostgreSQL.
