The point of the Accelerate.framework is that it is the API and also abstracts away hardware differences between the processors of macOS, iOS, tvOS, and watchOS devices.
>Accelerate provides high-performance, energy-efficient computation on the CPU by leveraging its vector-processing capability. The following Accelerate libraries abstract that capability so that code written for them executes appropriate instructions for the processor available at runtime
