c8g.48xlarge

Analysis

The c8g.48xlarge is a compute optimized instance in the c8g series with 192 vCPUs and 384 GiB of memory on AWS Graviton4 (up to 2.7 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.

Running it in Mumbai instead of São Paulo saves $4,779 a month per instance: $5.18/hour against $11.73/hour, a 126% spread.

It is the cheapest of the 5 processor variants AWS sells at this size and generation. The c8id.48xlarge on Intel Xeon Scalable (Granite Rapids) costs 39% more, and the c8i.48xlarge, the c8gd.48xlarge and the c8a.48xlarge also sit above it.

At $7.66/hour on demand in US East (N. Virginia), about $5,590 a month, the c8g.48xlarge is one of the cheaper ways to buy compute optimized capacity: only 17% of the 291 current compute optimized types cost less per vCPU-hour than its $0.0399.

The newer c9g.48xlarge on AWS Graviton5 is 9.0% dearer at $8.35/hour.

Looking beyond its own line, 1 of 14 current types with 192 vCPUs and similar memory are cheaper. The cheapest of those is the c6a.48xlarge on AMD EPYC 7R13 at $7.34/hour.

It is the largest of the 10 c8g sizes. Dropping to the c8g.24xlarge saves $2,795 a month.

Reserving it for a year with no upfront payment cuts the Linux rate to $5.05/hour, which beats on demand once it runs more than 66% of the time; three years brings it to $3.36/hour, 56% below on demand.
