public static int processorCount { get; }

Returns the number of "logical processors" (threads) as reported by the operating system. This is distinct from the number of physical cores. On CPUs with Hyper-Threading or simultaneous multithreading (SMT), a single physical core is split into two logical cores. For example, a CPU with 4 physical cores and 8 threads will return . On Android, it reports the number of active processors.

using UnityEngine;public class Example : MonoBehaviour{    void Start()    {        // Prints using the following format - "4" on a quad-core CPU.        print(SystemInfo.processorCount);    }}
