The F1 instance family, generally available since April 2017, features high-frequency Intel Xeon E5-2686 v4 (Broadwell) processors and Xilinx Virtex UltraScale+ VU9P FPGAs. These instances offer NVMe SSD storage and support for enhanced networking, providing up to 25 Gbps of network bandwidth depending on the instance size. F1 instances are designed for customizable hardware acceleration in the cloud, making them suitable for workloads like genomic sequencing, video processing, and big data analytics. As of April 2025, AWS has stopped supporting F1 instances for new users, with plans to gradually replace them with F2 instances.
