The x8i.metal-96xl pairs 384 vCPU with 6144 GiB of RAM, the 16.00 GiB-per-vCPU ratio that marks a memory-optimized instance. In the name, "x" is the extra-memory line, "8" is the generation, "i" marks Intel processors and "metal-96xl" is the size within the x8i family. It runs on Intel Xeon Scalable (Granite Rapids) at 3.9 GHz, and AWS introduced it in January 2026. x8i is the current generation of the x family, so there is no newer AWS size to migrate to. Spot's largest VM is 16 vCPU and 128 GiB, so matching this instance would take 44 × mh.vs1.2xlarge — arithmetically true and operationally absurd. The Spot column below prices that whole fleet, so read it as a scale reference rather than a drop-in replacement: at this size the useful question is what a shard of the workload costs, which is $0.021/hr per node.
