The m7g.8xlarge pairs 32 vCPU with 128 GiB of RAM, the 4.00 GiB-per-vCPU ratio that marks a general-purpose instance. In the name, "m" is the general-purpose line, "7" is the generation, "g" marks AWS Graviton (ARM) processors and "8xlarge" is the size within the m7g family. It runs on AWS Graviton3 Processor at 2.5 GHz, and AWS introduced it in February 2023. AWS has since shipped m8g and m9g; m8g.8xlarge is the direct replacement at this size, scoring 928,815 CoreMark/s against this instance's 815,390 — roughly 14% more throughput for the same vCPU count. Spot's node ladder tops out below this size, so m7g.8xlarge becomes 2 × gp.vs2.2xlarge (32 vCPU, 128 GiB combined), about 94% below the US East (N. Virginia) on-demand rate. Spot delivers compute as managed Kubernetes, so a node pool of that size is the native shape of the answer rather than a workaround — provided the workload scales horizontally.
