r6i.large

3rd generation Intel Xeon Scalable processors (Ice Lake) with an all-core turbo frequency of 3.5 GHz Memory-optimized instance family built on the AWS Nitro System, with an 8:1 memory-to-vCPU ratio. It is SAP-Certified, offers up to 15% better compute price performance than R5 instances, includes always-on memory encryption (Intel TME), and provides up to 50 Gbps networking and 40 Gbps of bandwidth to Amazon Elastic Block Store (EBS). Elastic Fabric Adapter (EFA) is supported on 32xlarge and metal sizes

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 r6i.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 r6i.large in your own account.

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