g3s.xlargeAWS Pricing, Specs & Benchmarks

The g3s family is a generation-3 GPU-accelerated (graphics + ML inference) line running on Intel Xeon (x86_64). g3s.xlarge provides 4 vCPUs and 30.5GB of RAM (a 1:8 vCPU-to-memory ratio), priced at $0.7500/hr On-Demand — about $540.00 per month at 24×7 utilization.

GPU-accelerated (graphics + ML inference) instances are sized for remote workstations, game streaming, ML inference, video transcoding, and graphics-heavy rendering pipelines. If your workload doesn't match that profile — for example, if you're running a memory-bound app on a compute-optimized instance, or a CPU-pegged batch job on a burstable t-series — you'll likely pay for capacity you can't use or run into bottlenecks you didn't anticipate. The pages for sibling families (linked further down) cover those alternatives in detail.

In the AWS instance-naming convention, the digit after the series letter is the generation — higher is newer. This appears to be one of AWS's newer generations in the series, so for most fresh workloads it's a reasonable default within its category.

Pricing varies by region (sometimes meaningfully — the gap between the cheapest and most expensive AWS region for the same SKU is often 15–30%). The regional pricing table further down shows where g3s.xlarge is cheapest today, both On-Demand and Spot.
