r7a.48xlarge

Analysis

The r7a.48xlarge is a memory optimized instance in the r7a series with 192 vCPUs and 1536 GiB of memory on AMD EPYC 9R14 (up to Up to 3.7 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.

Compared with the previous generation, it costs 34% more than the r6a.48xlarge on AMD EPYC 7R13 ($2,716 more a month per instance), in exchange for the newer processor. The newer r8a.48xlarge on AMD EPYC 9R45 is 5.0% dearer at $15.34/hour.

Within the same generation and size, the r7i.48xlarge on Intel Xeon Scalable (Sapphire Rapids) costs $12.70/hour, 13% less ($1,391 a month).

Running it in N. Virginia instead of Frankfurt saves $2,200 a month per instance: $14.61/hour against $17.62/hour, a 21% spread. It is not offered in Canada Central, São Paulo, London, Mumbai, Singapore and Sydney, so plan around that if you need a presence there.

On demand it costs $14.61/hour in US East (N. Virginia), $10,663 a month if left running, which puts it mid-table for memory optimized types at the 46th percentile per vCPU ($0.0761 per vCPU-hour) and the 62nd percentile per GiB ($0.00951 per GiB-hour).

Looking beyond its own line, 6 of 20 current types with 192 vCPUs and similar memory are cheaper. The cheapest of those is the r8g.48xlarge on AWS Graviton4 at $11.31/hour.
