Analysis
The r7g.12xlarge is a memory optimized instance in the r7g series with 48 vCPUs and 384 GiB of memory on AWS Graviton3 (up to 2.5 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Running it in Mumbai instead of São Paulo saves $1,671 a month per instance: $1.80/hour against $4.09/hour, a 127% spread.
At $2.57/hour on demand in US East (N. Virginia), about $1,876 a month, the r7g.12xlarge is one of the cheaper ways to buy memory optimized capacity: only 2% of the 385 current memory optimized types cost less per vCPU-hour than its $0.0535.
It is the cheapest of the 5 processor variants AWS sells at this size and generation. The r7iz.12xlarge on Intel Xeon Scalable (Sapphire Rapids) costs 74% more, and the r7i.12xlarge, the r7gd.12xlarge and the r7a.12xlarge also sit above it.
Compared with the previous generation, it costs 6.2% more than the r6g.12xlarge on AWS Graviton2 ($110 more a month per instance), in exchange for the newer processor. The newer r8g.12xlarge on AWS Graviton4 is 10% dearer at $2.83/hour.
It is size 7 of 8 in the r7g series. Stepping up to the r7g.16xlarge gives 64 vCPUs and 512 GiB for $625 more a month. Dropping to the r7g.8xlarge saves $625 a month.
