See the benchmarks for all EC2 instances.
This instance type is available for self-hosted GitHub Actions runners using RunsOn.
EC2 Instance family: m8i-flex
CPU Type: Custom Intel Xeon 6 processors with a sustained all-core 3.9 GHz turbo frequency.
Specific Features: A lower-cost, general-purpose variant designed for workloads that don't continuously use all compute resources. It offers a baseline CPU performance of 40% with the ability to burst up to 100% of CPU performance for 95% of the time over a 24-hour period. It uses the sixth-generation AWS Nitro Cards, providing improved network and EBS bandwidth, and supports bandwidth configuration adjustments. It features a 4.6x larger L3 cache and enhanced accelerators like Advanced Matrix Extensions (AMX).
Date of Release: August 28, 2025.
