Analysis
The hpc7g.4xlarge is a compute optimized instance in the hpc7g series with 16 vCPUs and 128 GiB of memory on AWS Graviton3 (up to 2.6 GHz), which makes it memory-heavy at 8 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.
Per vCPU it is one of the dearer compute optimized types: 99% of the 291 current types in the family cost less than its $0.1052 per vCPU-hour. The premium mostly pays for the very fast networking. On demand it is $1.68/hour in US East (N. Virginia), or $1,229 for a 730-hour month.
It is the smallest of the 3 hpc7g sizes. Stepping up to the hpc7g.8xlarge gives 32 vCPUs and 128 GiB for $0.00000 more 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.
Looking beyond its own line, 37 of 42 current types with 16 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.4xlarge on AWS Graviton2 at $0.8064/hour.
