192 vCPU · 1536 GiB · 600 Gigabit · AWS Graviton4 Processor Graviton
$17.4893/hour on-demand · $12,767/month (Linux, Shared)
r8gn.48xlarge is a memory-optimized EC2 instance with 192 vCPU and 1536 GiB, generation 8 of the r family on AWS Graviton (Arm). On-demand it costs $17.4893 an hour, about $12,767 a month if it runs all month. A one-year commitment with nothing up front works out at $11.0182 an hour and pays for itself above roughly 459 hours a month; below that, on-demand is cheaper. The three-year options go down to $7.0813 an hour, 60% below on-demand. The newer r8g.48xlarge offers the same size for $11.3107 an hour, 35% less. US East (N.
