r8idn.96xlarge

Analysis

The r8idn.96xlarge is a memory optimized instance in the r8idn series with 384 vCPUs and 3072 GiB of memory on Intel Xeon Scalable (Granite Rapids) (up to 3.9 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.

Within the same generation and size, the r8i.96xlarge on Intel Xeon Scalable (Granite Rapids) costs $26.67/hour, 41% less ($13,392 a month). The other variants are the r8id.96xlarge at $31.93, the r8ib.96xlarge at $40.17 and the r8in.96xlarge at $40.17.

Running it in N. Virginia instead of Tokyo saves $7,084 a month per instance: $45.02/hour against $54.72/hour, a 22% spread. It is not offered in Canada Central, São Paulo, London, Mumbai, Singapore and Sydney, so plan around that if you need a presence there.

Per vCPU it is one of the dearer memory optimized types: 87% of the 385 current types in the family cost less than its $0.1172 per vCPU-hour. The premium mostly pays for the local NVMe disk. On demand it is $45.02/hour in US East (N. Virginia), or $32,863 for a 730-hour month.

It has local instance storage (6 x 3800 GB NVMe SSD), which is fast but lost when the instance stops. Network: 600 Gigabit.

It is the largest of the 11 r8idn sizes. Dropping to the r8idn.48xlarge saves $16,432 a month.
