AZ-104 Certification Notes

Chapter 9.5 - ACUs

Azure Compute Units

Azure Compute Unit (ACU) provides a way of comparing compute (CPU) performance across Azure SKUs.

ACU is currently standardized on a Small (Standard_A1) VM with the value of 100. All other SKUs then represent approximately how much faster that SKU can run a standard benchmark.

• SKU Family
  • A1-A4
  • D1-D14
• ACU/vCPU
  • 100
  • 160-250
• vCPU: Core
  • 1:1
  • 1:1 D1-D14 are 60% to 150% more performant than the A1-A4
