EC2 r5a instance prices

The r5a series is a memory optimized EC2 line running on AMD EPYC 7571. It has 8 sizes, from the r5a.large with 2 vCPUs and 16 GiB to the r5a.24xlarge with 96 vCPUs and 768 GiB, and it is memory-heavy with a median of 8.0 GiB per vCPU.

In US East the Linux on-demand price runs from $0.1130/hour to $5.42/hour, or $82.49 to $3,960 a month. The median price per vCPU-hour across the series is $0.0565.

Every size costs the same $0.0565 per vCPU-hour, so price scales linearly: doubling the size doubles the bill, and two smaller instances cost exactly as much as one larger one. That makes it easy to start small and resize later without changing your unit cost. All sizes are sold in the same 12 of the 12 regions we track.
