The c8i.metal-96xl pairs 384 vCPU with 768 GiB of RAM, the 2.00 GiB-per-vCPU ratio that marks a compute-optimized instance. In the name, "c" stands for compute, "8" is the generation, "i" marks Intel processors and "metal-96xl" is the size within the c8i family. It runs on Intel Xeon Scalable (Granite Rapids) at 3.9 GHz, and AWS introduced it in October 2025. AWS has since shipped c9g. Spot's largest VM is 16 vCPU and 128 GiB, so matching this instance would take 24 × ch.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 $0.041/hr per node.
