Context
Notes
- Chip pricing not applicable - Graviton4 is AWS-internal and only consumed via EC2.
- The mission suggested c7g.16xlarge as the unit, but c7g instances are Graviton3(E); the Graviton4 compute family is c8g, which is used here.
- TDP and process node are not disclosed by AWS; omitted.
