f2.12xlargeAWS Pricing, Specs & Benchmarks

The f2 family is a generation-2 FPGA-accelerated line running on Intel Xeon (x86_64). f2.12xlarge provides 48 vCPUs and 512GB of RAM (a 1:11 vCPU-to-memory ratio), priced at $3.9600/hr On-Demand — about $2851.20 per month at 24×7 utilization.

FPGA-accelerated instances are sized for genomics, financial analytics, video processing, and any workload built against custom Xilinx FPGA 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 f2.12xlarge is cheapest today, both On-Demand and Spot. Spot pricing for f2.12xlarge is currently $1.1674/hr — roughly 71% off On-Demand — which makes the instance viable for fault-tolerant batch jobs, CI fleets, and any workload that can tolerate interruption with short notice.
