The m5.xlarge pairs 4 vCPU with 16 GiB of RAM, the 4.00 GiB-per-vCPU ratio that marks a general-purpose instance. In the name, "m" is the general-purpose line, "5" is the generation and "xlarge" is the size within the m5 family. It runs on Intel Xeon Platinum 8175 at 3.1 GHz, and AWS introduced it in November 2017. AWS has since shipped m6i, m7i, m8i and m9g; m6i.xlarge is the direct replacement at this size, scoring 66,742 CoreMark/s against this instance's 59,119 — roughly 13% more throughput for the same vCPU count. gp.vs1.large on Rackspace Spot lines up one-for-one: 4 vCPU and 16 GiB, about 94% below the US East (N. Virginia) on-demand rate.
