The t3.large is a general-purpose AWS EC2 instance: 2 vCPU and 8 GiB of memory, 4.00 GiB per vCPU. In the name, "t" is burstable, "3" is the generation and "large" is the size within the t3 family. It runs on Intel Skylake E5 2686 v5 at 3.1 GHz, and AWS introduced it in August 2018. AWS has since shipped t4g and t8i; t4g.large is the direct replacement at this size, scoring 39,596 CoreMark/s against this instance's 27,293 — roughly 45% more throughput for the same vCPU count. The nearest Spot node is gp.vs1.large at 4 vCPU and 16 GiB — 2 more vCPU and 8 GiB more memory, about 87% below the US East (N. Virginia) on-demand rate.
