r6i.8xlarge pricing and specs in Asia Pacific (Mumbai)
32 vCPU · 256 GiB · 12.5 Gigabit · Intel Xeon 8375C (Ice Lake) previous generation
$2.0800/hour on-demand · $1,518/month (Linux, Shared)
r6i.8xlarge is a memory-optimized EC2 instance with 32 vCPU and 256 GiB, generation 6 of the r family; AWS lists it as a previous generation. On-demand it costs $2.0800 an hour, about $1,518 a month if it runs all month. A one-year commitment with nothing up front works out at $1.3671 an hour and pays for itself above roughly 479 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.8212 an hour, 61% below on-demand. The newer r6g.8xlarge offers the same size for $1.0400 an hour, 50% less and moves to Graviton. Across regions the cheapest place to run r6i.8xlarge is US East (N. Virginia) (us-east-1) at $2.0160 an hour, 3% below Asia Pacific (Mumbai).

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.
