The c5n.large pairs 2 vCPU with 5.25 GiB of RAM, the 2.63 GiB-per-vCPU ratio that marks a compute-optimized instance. In the name, "c" stands for compute, "5" is the generation, "n" marks enhanced networking and "large" is the size within the c5n family. It runs on Intel Xeon Platinum 8124M at 3 GHz, and AWS introduced it in November 2018. AWS has since shipped c6i, c7i, c8i and c9g; c6i.large is the direct replacement at this size, scoring 35,321 CoreMark/s against this instance's 31,366 — roughly 13% more throughput for the same vCPU count. ch.vs1.large is the closest Spot shape: 4 vCPU and 8 GiB, so 2 more vCPU and 2.75 GiB more memory, about 81% below the US East (N. Virginia) on-demand rate.
