All Microsoft Fabric workloads consume the same Fabric Capacity Units, and there’s a Fabric SKU Estimator tool in public preview. Its aim is to help customers to identify the appropriate Fabric Capacity Unit SKU for their needs, based on their data requirements, usage patterns, and workload combinations.

Find the tool here: https://bit.ly/4pi1SDm, and there’s a useful page in the Learn documentation here: https://bit.ly/4ibpUO3 that demonstrates how the Fabric SKU Estimator might be used via a comprehensive sample scenario.
