EC2 r8gb instance prices

The r8gb series is a memory optimized EC2 line running on AWS Graviton4. It has 10 sizes, from the r8gb.medium with 1 vCPU and 8 GiB to the r8gb.48xlarge with 192 vCPUs and 1536 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 $0.0911/hour to $17.49/hour, or $66.50 to $12,767 a month. The median price per vCPU-hour across the series is $0.0911. These are Arm (Graviton) instances, which need arm64 builds of your software.

Every size costs the same $0.0911 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 2 of the 12 regions we track.
