‘R3’ instances are the memory optimized instances which are being provided by Amazon AWS. You can get more details about this instance family here.

In our previous benchmarking posts, we have benchmarked ‘i2’, ‘m3’, ‘c3’ instance families. In this post, we are sharing the results of CPU benchmarking for ‘r3’ instances. As in previous posts, we have used CoreMark for CPU benchmarking.

The following table shows the CoreMark score obtained for each of the ‘r3’ instance type.

Here is a chart of the same shown as a bar graph.

We also calculated the CoreMark score per dollar rent. We found that there is not much difference across the ‘r3’ instance family.
