EC2 c6a instance prices

The c6a series is a compute optimized EC2 line running on AMD EPYC 7R13. It has 10 sizes, from the c6a.large with 2 vCPUs and 4 GiB to the c6a.48xlarge with 192 vCPUs and 384 GiB, and it is compute-heavy with a median of 2.0 GiB per vCPU.

In US East the Linux on-demand price runs from $0.0765/hour to $7.34/hour, or $55.84 to $5,361 a month. The median price per vCPU-hour across the series is $0.0382.

Every size costs the same $0.0382 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.
