Therefore, instead of just four threads, a. This feature enables each core to handle two threads at once, effectively doubling the number of threads the processor can manage. 8 threads just means that two threads are sharing one core (assuming they are.
I expect if you specify more threads then. Typically, the number of threads the run truly concurrently is determined by the number of cpus and cpu cores (including hyper threading) you have. For example, if a cpu is dual core (i.e., 2 cores) it will have 4 threads.
The prevailing consensus is that having more physical cores is preferable to having more threads. Threads represent the virtual cores of a cpu. This means that your cpu can handle 4 threads simultaneously. In my experience, 4 cores means you can do 4 things at the same time with impunity.
In comparison, a cpu with 8 cores and 8 threads would perform better. Arm (apple m1 and later): That is to say that at.
