The r7g.2xlarge is a memory-optimized AWS EC2 instance: 8 vCPU and 64 GiB of memory, 8.00 GiB per vCPU. In the name, "r" stands for RAM, "7" is the generation, "g" marks AWS Graviton (ARM) processors and "2xlarge" is the size within the r7g family. It runs on AWS Graviton3 Processor at 2.5 GHz, and AWS introduced it in February 2023. AWS has since shipped r8g and r9g; r8g.2xlarge is the direct replacement at this size, scoring 240,583 CoreMark/s against this instance's 196,963 — roughly 22% more throughput for the same vCPU count. Rackspace Spot's mh.vs2.xlarge is a like-for-like substitute at 8 vCPU and 64 GiB, about 93% below the US East (N. Virginia) on-demand rate.
