m6id.12xlarge

Analysis

The m6id.12xlarge is a general purpose instance in the m6id series with 48 vCPUs and 192 GiB of memory on Intel Xeon 8375C (Ice Lake) (up to 3.5 GHz), which makes it balanced at 4 GiB of memory per vCPU.

Within the same generation and size, the m6g.12xlarge on AWS Graviton2 costs $1.85/hour, 35% less ($730 a month), though switching means rebuilding software for arm64. The other variants are the m6a.12xlarge at $2.07, the m6gd.12xlarge at $2.17 and the m6i.12xlarge at $2.30.

Running it in N. Virginia instead of São Paulo saves $1,233 a month per instance: $2.85/hour against $4.54/hour, a 59% spread.

On demand it costs $2.85/hour in US East (N. Virginia), $2,079 a month if left running, which puts it mid-table for general purpose types at the 56th percentile per vCPU ($0.0593 per vCPU-hour) and the 56th percentile per GiB ($0.0148 per GiB-hour).

It has local instance storage (2 x 1425 GB NVMe SSD), which is fast but lost when the instance stops. Network: 18750 Megabit.

Looking beyond its own line, 18 of 36 current types with 48 vCPUs and similar memory are cheaper. The cheapest of those is the m7g.12xlarge on AWS Graviton3 at $1.96/hour.

It is size 6 of 9 in the m6id series. Stepping up to the m6id.16xlarge gives 64 vCPUs and 256 GiB for $693 more a month. Dropping to the m6id.8xlarge saves $693 a month.
