Which one should you pick?
Pick GCP n2-highmem-16 if price is your primary constraint — it's $123.74/mo cheaper for the same 16 vCPU / 128 GiB profile, which adds up to $1,484.91/year at steady utilization.
Pick AWS r5.4xlarge if you're already committed to the AWS ecosystem — existing VPC/network setup, IAM policies, reserved capacity, or team expertise on AWS usually outweighs a 17% list-price gap on a single instance. Cross-provider migration cost rarely pays for itself on compute pricing alone.
Either way, this is a single-instance, on-demand comparison. Reserved/committed-use discounts (up to ~72% on both platforms) and your actual utilization pattern will move the real numbers — model your full workload with the calculator before deciding.
