EC2 r7i instance prices

The r7i series is a memory optimized EC2 line running on Intel Xeon Scalable (Sapphire Rapids). It has 9 sizes, from the r7i.large with 2 vCPUs and 16 GiB to the r7i.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 $0.1323/hour to $12.70/hour, or $96.58 to $9,272 a month. The median price per vCPU-hour across the series is $0.0662.

Every size costs the same $0.0662 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.
