Analysis
The x2idn.16xlarge is a memory optimized instance in the x2idn series with 64 vCPUs and 1024 GiB of memory on Intel Xeon Scalable (Icelake) (up to 3.5 GHz), which makes it very memory-heavy at 16 GiB of memory per vCPU.
Within the same generation and size, the x2gd.16xlarge on AWS Graviton2 costs $5.34/hour, 20% less ($967 a month), though switching means rebuilding software for arm64. The other variants are the x2iedn.16xlarge at $13.34.
Running it in N. Virginia instead of São Paulo saves $4,625 a month per instance: $6.67/hour against $13.01/hour, a 95% spread.
Per vCPU it is one of the dearer memory optimized types: 76% of the 385 current types in the family cost less than its $0.1042 per vCPU-hour. The premium mostly pays for the local NVMe disk. On demand it is $6.67/hour in US East (N. Virginia), or $4,868 for a 730-hour month.
It has local instance storage (1 x 1900 GB NVMe SSD), which is fast but lost when the instance stops. Network: 50 Gigabit.
Looking beyond its own line, 3 of 7 current types with 64 vCPUs and similar memory are cheaper. The cheapest of those is the hpc6id.32xlarge on Intel Xeon Scalable (Icelake) at $5.70/hour.
