AWS EC2 Instances Benchmark
AWS sometimes uses custom CPU types that you won’t find listed on sites like Passmark, etc. So it’s hard to know which one to pick, if you’re looking for the fastest CPU around.
On this page we provide up-to-date CPU benchmarks for most EC2 instance types, across many regions. This can be used to make an informed decision on the best instance to select for your workflows, based on the processor model, architecture, and single-thread CPU speed.
And since speed isn’t everything, the benchmark also lists the on-demand and spot pricing for each instance type, with the trend over time. Percentage of interruption for each instance type is also provided, giving you a clear picture of what to expect in terms of stability when using spot instances.
Note that this benchmark is regularly updated so that RunsOn users can choose the best-performing EC2 instance for their GitHub Actions workflows.
Results
Note: All instance types are launched using the 2 vCPU variant. As always, it’s best to perform your own benchmarks yourself, but this can at least give you some hints in the right direction.
