m8idb.2xlarge is AWS's general-purpose EC2 size at 8 vCPU and 32 GiB. In the name, "m" is the general-purpose line, "8" is the generation, "idb" marks Intel processors, local NVMe storage and block-storage optimisation and "2xlarge" is the size within the m8idb family. It runs on Intel Xeon Scalable (Granite Rapids) at 3.9 GHz, and AWS introduced it in May 2026. AWS has since shipped m9g; m9g.2xlarge is the direct replacement at this size, scoring 290,293 CoreMark/s against this instance's 186,763 — roughly 55% more throughput for the same vCPU count. On Rackspace Spot the same shape is gp.vs2.xlarge — 8 vCPU, 32 GiB, matched on both dimensions, $0.764/hr on AWS in US East (N. Virginia), from $0.031/hr on Rackspace Spot.
