AWS Graviton4 processor Compute-optimized, delivers up to 30% better performance than Graviton3-based C7g instances, built on the AWS Nitro System, and offers enhanced networking bandwidth up to 50 Gbps and up to 40 Gbps to Amazon EBS. It is ideal for compute-intensive workloads such as HPC, batch processing, and CPU-based machine learning inference

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 c8g.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 c8g.large in your own account.
The benchmark runs on the same RunsOn anyone can deploy. One CloudFormation stack, your AWS account, ~10 minutes.
