m7i-flex.m7i-flex.large

** Custom 4th Gen Intel Xeon Scalable processors (code name Sapphire Rapids). ** ** General-purpose instance that delivers a baseline of 40% CPU performance and can scale up to full CPU performance a majority of the time, making them a lower-cost variant for workloads that don't require continuous full CPU utilization. They also support Intel Advanced Matrix Extensions (AMX). **

availability & price by region

Spot is the average price RunsOn pays in your own AWS account — no per-minute markup. The bar shows how far under on-demand each region runs; the badge is the observed spot-interruption frequency.

Spot prices are trailing averages per region and move with the market. On-demand is the list reference. Interrupt frequency is AWS's published spot-advisor band for this instance type.

about these benchmarks

CPU is the Passmark single-thread metric, run on a live m7i-flex.large instance and averaged over many days so a single noisy run can't skew the score.

Pricing is normalized to the hourly rate AWS bills, then shown per region. Spot is the trailing average; savings is measured against the same region's on-demand list price.

This instance is launched the exact same way any RunsOn job launches it — ephemeral EC2 in your account, one CloudFormation stack, nothing to babysit.

run m7i-flex.large in your own account.

The benchmark runs on the same RunsOn anyone can deploy. One CloudFormation stack, your AWS account, ~10 minutes.
