The x2iedn.32xlarge is a memory-optimized AWS EC2 instance: 128 vCPU and 4096 GiB of memory, 32.00 GiB per vCPU. In the name, "x" is the extra-memory line, "2" is the generation, "iedn" marks Intel processors, extended capacity, local NVMe storage and enhanced networking and "32xlarge" is the size within the x2iedn family. It runs on Intel Xeon Scalable (Icelake) at 3.5 GHz, and AWS introduced it in March 2022. AWS has since shipped x8i; x8i.32xlarge is the direct replacement at this size, scoring 3,045,263 CoreMark/s against this instance's 2,111,950 — roughly 44% more throughput for the same vCPU count. Spot's largest VM is 16 vCPU and 128 GiB, so matching this instance would take 30 × 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.
