hpc7g.16xlarge

Analysis

The hpc7g.16xlarge is a compute optimized instance in the hpc7g series with 64 vCPUs and 128 GiB of memory on AWS Graviton3 (up to 2.6 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.

Running it in N. Virginia instead of Tokyo saves $313 a month per instance: $1.68/hour against $2.11/hour, a 25% spread. It is not offered in Ohio, Oregon, Canada Central, São Paulo, London, Frankfurt, Mumbai, Singapore and Sydney, so plan around that if you need a presence there.

Nothing else with 64 vCPUs and similar memory is cheaper: among 28 current same-shape types it has the lowest on-demand price.

At $1.68/hour on demand in US East (N. Virginia), about $1,229 a month, the hpc7g.16xlarge is one of the cheaper ways to buy compute optimized capacity: only 1% of the 291 current compute optimized types cost less per vCPU-hour than its $0.0263.

It is the largest of the 3 hpc7g sizes. Dropping to the hpc7g.8xlarge saves $0.00000 a month. Unit price is not flat across the series ($0.0263 to $0.1052 per vCPU-hour), so the size changes the rate you pay.

Reserving it for a year with no upfront payment cuts the Linux rate to $1.33/hour, which beats on demand once it runs more than 79% of the time; three years brings it to $1.16/hour, 31% below on demand.
