The c8ine.8xlarge pairs 32 vCPU with 64 GiB of RAM, the 2.00 GiB-per-vCPU ratio that marks a compute-optimized instance. In the name, "c" stands for compute, "8" is the generation, "ine" marks Intel processors, enhanced networking and extended capacity and "8xlarge" is the size within the c8ine family. It runs on Intel Xeon Scalable (Granite Rapids) at 3.9 GHz, and AWS introduced it in April 2026. AWS has since shipped c9g; c9g.8xlarge is the direct replacement at this size, scoring 1,163,636 CoreMark/s against this instance's 796,813 — roughly 46% more throughput for the same vCPU count. Spot's node ladder tops out below this size, so c8ine.8xlarge becomes 2 × ch.vs1.2xlarge (32 vCPU, 64 GiB combined), $2.72/hr on AWS in US East (N. Virginia), from $0.082/hr on Rackspace Spot. Spot delivers compute as managed Kubernetes, so a node pool of that size is the native shape of the answer rather than a workaround — provided the workload scales horizontally.
Match qualityScale-out match
c8ine.8xlarge gives you 32 vCPU and 64 GiB in a single machine. The largest comparable Spot node, ch.vs1.2xlarge, is 16 vCPU and 32 GiB, so the equivalent here is 2 nodes rather than one.
Spot runs as managed Kubernetes, so a 2-node pool is the normal way to run things rather than a workaround. If your workload already sits behind a load balancer, a queue or a scheduler, it spreads across them without changes. If it needs all 32 cores and 64 GiB in one process, it does not.
