Analysis
The r8gd.xlarge is a memory optimized instance in the r8gd series with 4 vCPUs and 32 GiB of memory on AWS Graviton4 (up to 2.7 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Within the same generation and size, the r8g.xlarge on AWS Graviton4 costs $0.2356/hour, 20% less ($42.54 a month). The other variants are the r8i-flex.xlarge at $0.2639, the r8i.xlarge at $0.2778 and the r8a.xlarge at $0.3195.
Running it in Mumbai instead of São Paulo saves $201 a month per instance: $0.1901/hour against $0.4654/hour, a 145% spread.
Compared with the previous generation, it costs 8.0% more than the r7gd.xlarge on AWS Graviton3 ($15.86 more a month per instance), in exchange for the newer processor. The newer r9gd.xlarge on AWS Graviton5 is 9.0% dearer at $0.3204/hour.
On demand it costs $0.2939/hour in US East (N. Virginia), $215 a month if left running, which puts it mid-table for memory optimized types at the 37th percentile per vCPU ($0.0735 per vCPU-hour) and the 53rd percentile per GiB ($0.00919 per GiB-hour).
It has local instance storage (1 x 237 GB NVMe SSD), which is fast but lost when the instance stops. Network: Up to 12500 Megabit.
Looking beyond its own line, 16 of 45 current types with 4 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.xlarge on AWS Graviton2 at $0.2016/hour.
