AWS EC2 Instance Comparisons
Every popular AWS EC2 pair side-by-side — Intel vs AMD vs Graviton, generation upgrades, and same-family sizing. Each comparison page shows live pricing, Sysbench benchmarks, and architecture differences pulled from CloudBench's catalog.
Cross-architecture comparisons
When you need to decide between Intel, AMD, and Graviton at the same vCPU/RAM tier. These are the most common "is the architecture switch worth it" questions.

Same-family size comparisons
When you're right-sizing within a family — same silicon, same architecture, just bigger or smaller. Pricing within a family scales close to linearly, so these comparisons are mostly about how much capacity you actually need.
