The i7ie.3xlarge pairs 12 vCPU with 96 GiB of RAM, the 8.00 GiB-per-vCPU ratio that marks a storage-optimized instance. In the name, "i" is I/O, meaning local storage, "7" is the generation, "ie" marks Intel processors and extended capacity and "3xlarge" is the size within the i7ie family. It runs on Intel Xeon Scalable (Emerald Rapids) at 3.2 GHz, and AWS introduced it in December 2024. AWS has since shipped i8g; i8ge.3xlarge is the direct replacement at this size, scoring 374,707 CoreMark/s against this instance's 270,621 — roughly 38% more throughput for the same vCPU count. mh.vs1.2xlarge is the closest Spot shape: 16 vCPU and 128 GiB, so 4 more vCPU and 32 GiB more memory, $1.56/hr on AWS in US East (N. Virginia), from $0.021/hr on Rackspace Spot.
