x2iedn.24xlarge

Analysis

The x2iedn.24xlarge is a memory optimized instance in the x2iedn series with 96 vCPUs and 3072 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.24xlarge on Intel Xeon Scalable (Icelake) costs $10.00/hour, 50% less ($7,303 a month).

Nothing else with 96 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 $13,876 a month per instance: $20.01/hour against $39.02/hour, a 95% spread.

Per vCPU it is one of the dearer memory optimized types: 95% 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 $20.01/hour in US East (N. Virginia), or $14,605 for a 730-hour month.

It has local instance storage (2 x 1425 GB NVMe SSD), which is fast but lost when the instance stops. Network: 75 Gigabit.

Reserving it for a year with no upfront payment cuts the Linux rate to $12.31/hour, which beats on demand once it runs more than 62% of the time; three years brings it to $6.42/hour, 68% below on demand. Windows Server roughly adds 22% to the bill at $24.42/hour, because the licence is charged per vCPU.
