x2iedn.32xlarge

Analysis

The x2iedn.32xlarge is a memory optimized instance in the x2iedn series with 128 vCPUs and 4096 GiB of memory on Intel Xeon Scalable (Icelake) (up to 3.5 GHz), which makes it very memory-heavy at 32 GiB of memory per vCPU.

Within the same generation and size, the x2idn.32xlarge on Intel Xeon Scalable (Icelake) costs $13.34/hour, 50% less ($9,737 a month).

Nothing else with 128 vCPUs and similar memory is cheaper: among 2 current same-shape types it has the lowest on-demand price.

Running it in N. Virginia instead of São Paulo saves $18,501 a month per instance: $26.68/hour against $52.02/hour, a 95% spread.

Per vCPU it is one of the dearer memory optimized types: 94% of the 385 current types in the family cost less than its $0.2084 per vCPU-hour. The premium mostly pays for the local NVMe disk. On demand it is $26.68/hour in US East (N. Virginia), or $19,473 for a 730-hour month.

It has local instance storage (2 x 1900 GB NVMe SSD), which is fast but lost when the instance stops. Network: 100 Gigabit.

Reserving it for a year with no upfront payment cuts the Linux rate to $16.41/hour, which beats on demand once it runs more than 62% of the time; three years brings it to $8.56/hour, 68% below on demand. Windows Server roughly adds 22% to the bill at $32.56/hour, because the licence is charged per vCPU.
