c7gd.large

Analysis

The c7gd.large is a compute optimized instance in the c7gd series with 2 vCPUs and 4 GiB of memory on AWS Graviton3 (up to 2.5 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.

Within the same generation and size, the c7g.large on AWS Graviton3 costs $0.0725/hour, 20% less ($13.29 a month). The other variants are the c7i-flex.large at $0.0848, the c7i.large at $0.0892 and the c7a.large at $0.1026.

Running it in Mumbai instead of São Paulo saves $60.74 a month per instance: $0.0576/hour against $0.1408/hour, a 144% spread.

Compared with the previous generation, it costs 18% more than the c6gd.large on AWS Graviton2 ($10.15 more a month per instance), in exchange for the newer processor. The newer c8gd.large on AWS Graviton4 is 8.0% dearer at $0.0980/hour.

On demand it costs $0.0907/hour in US East (N. Virginia), $66.21 a month if left running, which puts it mid-table for compute optimized types at the 42nd percentile per vCPU ($0.0454 per vCPU-hour) and the 46th percentile per GiB ($0.0227 per GiB-hour).

It has local instance storage (1 x 118 GB NVMe SSD), which is fast but lost when the instance stops. Network: Up to 12500 Megabit.

Looking beyond its own line, 19 of 36 current types with 2 vCPUs and similar memory are cheaper. The cheapest of those is the t4g.medium on AWS Graviton2 at $0.0336/hour. It is burstable, so it only suits workloads that do not run the CPU flat out.
