g3.16xlargeAWS Pricing, Specs & Benchmarks

The g3 family is a generation-3 GPU-accelerated (graphics + ML inference) line running on Intel Xeon (x86_64). g3.16xlarge provides 64 vCPUs and 488GB of RAM (a 1:8 vCPU-to-memory ratio), priced at $4.5600/hr On-Demand — about $3283.20 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. AWS's current-generation alternative in the same series is **g4dn**, which generally offers better price/performance on newer silicon; if you're spinning up a new workload it's usually worth comparing the two before committing.

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 g3.16xlarge is cheapest today, both On-Demand and Spot. Spot pricing for g3.16xlarge isn't currently available; check back as AWS publishes spot rates intermittently in some regions.
