48 vCPU · 384 GiB · 10 Gigabit · AMD EPYC 7571
$1.9930/hour on-demand · $1,455/month (Linux, Shared)
r5ad.12xlarge is a memory-optimized EC2 instance with 48 vCPU and 384 GiB, generation 5 of the r family. On-demand it costs $1.9930 an hour, about $1,455 a month if it runs all month. A one-year commitment with nothing up front works out at $1.2560 an hour and pays for itself above roughly 460 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.7494 an hour, 62% below on-demand. The newer r6g.12xlarge offers the same size for $1.5600 an hour, 22% less and moves to Graviton.

Newer generations of the same size
Same family letter and size in a newer generation, ranked by price. “vCPU per $” uses vCPU as the performance proxy — newer chips usually add more, so it is a floor.
