We have created the concept of the Azure Compute Unit (ACU) to provide 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.
| SKU Family | ACU/Core |
|---|---|
| A0 | 50 |
| A1-A4 | 100 |
| A5-A7 | 100 |
| A1_v2-A8_v2 | 100 |
| A2m_v2-A8m_v2 | 100 |
| A8-A11 | 225* |
| D1-D14 | 160 |
| D1_v2-D15_v2 | 210 - 250* |
| DS1-DS14 | 160 |
| DS1_v2-DS15_v2 | 210-250* |
| F1-F16 | 210-250* |
| F1s-F16s | 210-250* |
| G1-G5 | 180 - 240* |
| GS1-GS5 | 180 - 240* |
| H | 290 - 300* |
| L4s-L32s | 180 - 240* |
ACUs marked with a * use Intel® Turbo technology to increase CPU frequency and provide a performance boost. The amount of the boost can vary based on the VM size, workload, and other workloads running on the same host.
