Analysis
The r8i.2xlarge is a memory optimized instance in the r8i series with 8 vCPUs and 64 GiB of memory on Intel Xeon Scalable (Granite Rapids) (up to 3.9 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Within the same generation and size, the r8g.2xlarge on AWS Graviton4 costs $0.4713/hour, 15% less ($61.61 a month), though switching means rebuilding software for arm64. The other variants are the r8i-flex.2xlarge at $0.5279, the r8gd.2xlarge at $0.5878 and the r8a.2xlarge at $0.6390.
Running it in N. Virginia instead of São Paulo saves $241 a month per instance: $0.5557/hour against $0.8864/hour, a 60% spread.
On demand it costs $0.5557/hour in US East (N. Virginia), $406 a month if left running, which puts it mid-table for memory optimized types at the 31st percentile per vCPU ($0.0695 per vCPU-hour) and the 44th percentile per GiB ($0.00868 per GiB-hour).
Compared with the previous generation, it costs 5.0% more than the r7i.2xlarge on Intel Xeon Scalable (Sapphire Rapids) ($19.33 more a month per instance), in exchange for the newer processor.
Looking beyond its own line, 14 of 45 current types with 8 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.2xlarge on AWS Graviton2 at $0.4032/hour.
