x8aedz.24xlarge

Analysis

The x8aedz.24xlarge is a memory optimized instance in the x8aedz series with 96 vCPUs and 3072 GiB of memory on AMD EPYC 9R05 (up to Up to 5 GHz), which makes it very memory-heavy at 32 GiB of memory per vCPU.

Within the same generation and size, the x8g.24xlarge on AWS Graviton4 costs $9.38/hour, 66% less ($13,312 a month), though switching means rebuilding software for arm64. The other variants are the x8i.24xlarge at $10.50.

Running it in Oregon instead of Tokyo saves $9,072 a month per instance: $27.61/hour against $40.04/hour, a 45% spread. It is not offered in N. Virginia, Ohio, Canada Central, São Paulo, London, Frankfurt, Singapore and Sydney, so plan around that if you need a presence there.

Per vCPU it is one of the dearer memory optimized types: 99% of the 385 current types in the family cost less than its $0.2877 per vCPU-hour. The premium mostly pays for the local NVMe disk. On demand it is $27.61/hour in its cheapest tracked region, or $20,159 for a 730-hour month.

Looking beyond its own line, 1 of 2 current types with 96 vCPUs and similar memory are cheaper. The cheapest of those is the x2iedn.24xlarge on Intel Xeon Scalable (Icelake) at $20.01/hour.
