The g6e.48xlarge is a GPU AWS EC2 instance: 192 vCPU and 1536 GiB of memory, 8.00 GiB per vCPU. In the name, "g" is graphics, "6" is the generation, "e" marks extended capacity and "48xlarge" is the size within the g6e family. It runs on AMD EPYC 7R13 Processor at 2.6 GHz, and AWS introduced it in August 2024. AWS has since shipped g7e; g7e.48xlarge is the direct replacement at this size, scoring 4,097,020 CoreMark/s against this instance's 3,635,503 — roughly 13% more throughput for the same vCPU count. Rackspace Spot has no equivalent to offer: 8 × NVIDIA L40S wired together behind a high-speed interconnect is one tightly coupled machine, not 8 independent nodes — and that interconnect is usually what the instance was bought for. Spot's largest VM tops out at 16 vCPU and 128 GiB, and even that is not the missing piece here. The table below prices what AWS charges; the honest answer on the Spot side is that this workload stays where it is.
