r7i.large
Custom 4th Generation Intel Xeon Scalable processors (Sapphire Rapids). Next-generation memory-optimized instance (8:1 memory to vCPU ratio), up to 15% better price-performance than R6i, uses DDR5 memory, supports Intel Advanced Matrix Extensions (AMX), and allows up to 128 EBS volumes. Bare metal sizes support Intel Data Streaming Accelerator (DSA), In-Memory Analytics Accelerator (IAA), and QuickAssist Technology (QAT).

Availability & price by region
Spot is the 7-day average of the cheapest zone's spot price in each region, from the RunsOn finder: an estimate of an hour in your own AWS account, where RunsOn adds no markup. The bar shows how far it runs under on-demand; the badge is AWS's spot-interruption band for the type.

Spot is the cheapest availability zone's spot price at each of the RunsOn finder's fetches (every 90 minutes), averaged over 7 days; on-demand is the Linux list price. Savings compare the two. Prices fetched 12 Oct 2026. The interruption band is AWS Spot Advisor's, fetched 12 Oct 2026.
About these benchmarks
The open benchmark harness launches r7i.large as a RunsOn runner and runs PassMark PerformanceTest (CPU Single
Threaded and CPU Mark), sysbench on one thread and on every thread, and 7-Zip's built-in benchmark. These numbers come from the
EC2 CPU sweep, the suite that measured this type in the most runs; each is the median over its runs of the current
workload definition in the last 75 days.
A type takes a place once it has 3 runs. A type within 5% of the type heading its group shares that place (“joint #2”); a lead under 5% is no lead.
Prices come from the RunsOn finder for the four regions shown; savings compare its 7-day average spot price with the on-demand price. RunsOn launches this type the same way for any job: ephemeral EC2 in your account, one CloudFormation stack. More in the methodology.
Run r7i.large in your own account.
The benchmark runs on the same RunsOn anyone can deploy. One CloudFormation stack, your AWS account, ~10 minutes.
