m1cpu

The go-m1cpu module is a library for inspecting Apple Silicon CPUs in Go.

Use the m1cpu library for looking up the CPU frequency for Apple M1 and M2 CPUs.

Install

go get github.com/shoenig/go-m1cpu@latest

Example

package main

import (
	"fmt"

	"github.com/shoenig/go-m1cpu"
)

func main() {
	fmt.Println("Apple Silicon", m1cpu.IsAppleSilicon())

	fmt.Println("pCore GHz", m1cpu.PCoreGHz())
	fmt.Println("eCore GHz", m1cpu.ECoreGHz())

	fmt.Println("pCore Hz", m1cpu.PCoreHz())
	fmt.Println("eCore Hz", m1cpu.ECoreHz())
}

CGO

This package requires the use of CGO. Extracting the CPU properties is done via Apple's IOKit framework, which is accessible only through system C libraries.
