Azure 计算单元 (ACU)Azure compute unit (ACU)

Azure 计算单位 (ACU) 这一概念提供一种比较 Azure SKU 的计算 (CPU) 性能的方法。The concept of the Azure Compute Unit (ACU) provides a way of comparing compute (CPU) performance across Azure SKUs. 这有助于轻松确定最有可能满足性能需求的 SKU。This will help you easily identify which SKU is most likely to satisfy your performance needs. ACU 目前在数量为 100 的小型 (Standard_A1) VM 上标准化,而所有其他 SKU 则表示该 SKU 在运行标准基准测试时大约会快多少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

*ACU 使用 Intel® Turbo 技术来增加 CPU 频率和提升性能。*ACUs use Intel® Turbo technology to increase CPU frequency and provide a performance increase. 性能提升程度可能因 VM 大小、工作负荷和同一主机上运行的其他工作负荷而有所不同。The amount of the performance increase can vary based on the VM size, workload, and other workloads running on the same host.

**ACU 使用 AMD® Boost 技术来增加 CPU 频率和提升性能。**ACUs use AMD® Boost technology to increase CPU frequency and provide a performance increase. 性能提升程度可能因 VM 大小、工作负荷和同一主机上运行的其他工作负荷而有所不同。The amount of the performance increase can vary based on the VM size, workload, and other workloads running on the same host.

***超线程,能够运行嵌套虚拟化***Hyper-threaded and capable of running nested virtualization

重要

ACU 只是一种规则。The ACU is only a guideline. 工作负荷的结果可能会有所不同。The results for your workload may vary.
