r7g.large

Analysis

The r7g.large is a memory optimized instance in the r7g series with 2 vCPUs and 16 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 $69.57 a month per instance: $0.0751/hour against $0.1704/hour, a 127% spread.

At $0.1071/hour on demand in US East (N. Virginia), about $78.18 a month, the r7g.large is one of the cheaper ways to buy memory optimized capacity: only 3% of the 385 current memory optimized types cost less per vCPU-hour than its $0.0536.

It is the cheapest of the 5 processor variants AWS sells at this size and generation. The r7iz.large on Intel Xeon Scalable (Sapphire Rapids) costs 74% more, and the r7i.large, the r7gd.large and the r7a.large also sit above it.

Compared with the previous generation, it costs 6.2% more than the r6g.large on AWS Graviton2 ($4.60 more a month per instance), in exchange for the newer processor. The newer r8g.large on AWS Graviton4 is 10% dearer at $0.1178/hour.

It is size 2 of 8 in the r7g series. Stepping up to the r7g.xlarge gives 4 vCPUs and 32 GiB for $78.18 more a month. Dropping to the r7g.medium saves $39.05 a month.
