c7i.48xlarge is AWS's compute-optimized EC2 size at 192 vCPU and 384 GiB. In the name, "c" stands for compute, "7" is the generation, "i" marks Intel processors and "48xlarge" is the size within the c7i family. It runs on Intel Xeon Scalable (Sapphire Rapids) at 3.2 GHz, and AWS introduced it in September 2023. AWS has since shipped c8i and c9g; c8i.48xlarge is the direct replacement at this size, scoring 4,448,821 CoreMark/s against this instance's 3,925,310 — roughly 13% more throughput for the same vCPU count. The closest Spot shape is ch.vs1.2xlarge at 16 vCPU, so this instance maps to 12 of them — 192 vCPU and 384 GiB across the fleet, 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.
