The m6idn.4xlarge is a general-purpose AWS EC2 instance: 16 vCPU and 64 GiB of memory, 4.00 GiB per vCPU. In the name, "m" is the general-purpose line, "6" is the generation, "idn" marks Intel processors, local NVMe storage and enhanced networking and "4xlarge" is the size within the m6idn family. It runs on Intel Xeon 8375C (Ice Lake) at 3.5 GHz, and AWS introduced it in November 2022. AWS has since shipped m7i, m8idn and m9g; m7i.4xlarge is the direct replacement at this size, scoring 372,382 CoreMark/s against this instance's 278,843 — roughly 34% more throughput for the same vCPU count. Rackspace Spot's gp.vs2.2xlarge is a like-for-like substitute at 16 vCPU and 64 GiB, $1.27/hr on AWS in US East (N. Virginia), from $0.041/hr on Rackspace Spot.
