How to compare PBI Premium capacities with AAS instances in terms of performance?

[Alibek]

Hello!

When migrating tabular models from AAS to PBI Premium capacity, we would like to know which pricing tier / capacity level would satisfy our requirements based on what is currently working (AAS tabular models). However, I have not been able to find any mappings from PBI Premium capacities' configurations with AAS instance tiers. They also use different "units" (Capacity Units vs Query Processing Units). Is such a comparison possible, and sensible thing to do?

Hi @Alibek,

Perhaps you can take a look at the following links about power bi premium license FAQ and different level of licenses in fabric if they help with your scenario:

Well, I found a mapping from PBI Premium capacity to Fabric capacity (P1 -> F64), but not to AAS instances.

I've only managed to find some blogpost where they claim that 100 QPUs ~ 5 CPU cores. But PBI capacities use something called Power BI v-cores, which I assume is something different and we need a mapping for that as well.
