Benchmarks for c7i-flex.large

CPU benchmark for the c7i-flex.large EC2 instance type, as well as the availability, pricing, and spot interruption percentage in various regions.

See the benchmarks for all EC2 instances.

This instance type is available for self-hosted GitHub Actions runners using RunsOn.

EC2 Instance family: c7i-flex

CPU type: Custom 4th Generation Intel Xeon Scalable Processors (Sapphire Rapids), exclusive to AWS.

Specific features: These are compute-optimized Flex instances designed for workloads that do not require continuous full CPU utilization. They offer a baseline level of CPU performance but can scale up to full compute performance 95% of the time. They utilize DDR5 memory and provide up to 19% better price performance compared to C6i instances.

Date of release: May 14, 2024 (General Availability announcement).
