Azure compute unit (ACU)

The concept of the Azure Compute Unit (ACU) provides a way of comparing compute (CPU) performance across Azure SKUs. This will help you easily identify which SKU is most likely to satisfy your performance needs. ACU is currently standardized on a Small (Standard_A1) VM being 100 and all other SKUs then represent approximately how much faster that SKU can run a standard benchmark.

Important

The ACU is only a guideline. The results for your workload may vary.

*ACUs use Intel® Turbo technology to increase CPU frequency and provide a performance increase. The amount of the performance increase can vary based on the VM size, workload, and other workloads running on the same host.

**ACUs use AMD® Boost technology to increase CPU frequency and provide a performance increase. The amount of the performance increase can vary based on the VM size, workload, and other workloads running on the same host.

***Hyper-threaded and capable of running nested virtualization
