Analysis
The x2gd.12xlarge is a memory optimized instance in the x2gd series with 48 vCPUs and 768 GiB of memory on AWS Graviton2 (up to 2.5 GHz), which makes it very memory-heavy at 16 GiB of memory per vCPU.
Nothing else with 48 vCPUs and similar memory is cheaper: among 4 current same-shape types it has the lowest on-demand price.
Running it in N. Virginia instead of Ireland saves $578 a month per instance: $4.01/hour against $4.80/hour, a 20% spread. It is not offered in Canada Central, São Paulo, London, Frankfurt, Mumbai, Singapore, Sydney and Tokyo, so plan around that if you need a presence there.
It is the cheapest of the 2 processor variants AWS sells at this size and generation. The x2iezn.12xlarge on Intel Xeon Platinum 8252 costs 150% more, and no others also sit above it.
On demand it costs $4.01/hour in US East (N. Virginia), $2,926 a month if left running, which puts it mid-table for memory optimized types at the 57th percentile per vCPU ($0.0835 per vCPU-hour) and the 1st percentile per GiB ($0.00522 per GiB-hour).
It has local instance storage (2 x 1425 GB SSD), which is fast but lost when the instance stops. Network: 20 Gigabit.
