The t8i.micro pairs 2 vCPU with 1 GiB of RAM, the 0.50 GiB-per-vCPU ratio that marks a general-purpose instance. In the name, "t" is burstable, "8" is the generation, "i" marks Intel processors and "micro" is the size within the t8i family. It runs on Intel Xeon Scalable (Granite Rapids) at 3.9 GHz, and AWS introduced it in September 2026. t8i is the current generation of the t family, so there is no newer AWS size to migrate to. gp.vs2.medium on Rackspace Spot lines up one-for-one: 2 vCPU and 4 GiB, about 84% below the US East (N. Virginia) on-demand rate.
