Analysis
The r8gn.48xlarge is a memory optimized instance in the r8gn series with 192 vCPUs and 1536 GiB of memory on AWS Graviton4 (up to 2.8 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Within the same generation and size, the r8g.48xlarge on AWS Graviton4 costs $11.31/hour, 35% less ($4,510 a month). The other variants are the r8i.48xlarge at $13.34, the r8gd.48xlarge at $14.11 and the r8a.48xlarge at $15.34.
Its price is almost flat across the 2 regions that offer it ($17.49 to $17.49/hour), so latency and data residency should decide where it runs. It is not offered in Ohio, Canada Central, São Paulo, Ireland, London, Frankfurt, Mumbai, Singapore, Sydney and Tokyo, so plan around that if you need a presence there.
On demand it costs $17.49/hour in US East (N. Virginia), $12,767 a month if left running, which puts it mid-table for memory optimized types at the 66th percentile per vCPU ($0.0911 per vCPU-hour) and the 81st percentile per GiB ($0.0114 per GiB-hour).
Looking beyond its own line, 12 of 20 current types with 192 vCPUs and similar memory are cheaper. The cheapest of those is the r6a.48xlarge on AMD EPYC 7R13 at $10.89/hour.
It is the largest of the 10 r8gn sizes. Dropping to the r8gn.24xlarge saves $6,384 a month.
