What does 12 cores and 16 threads mean?

12 cores and 16 threads means that there are 12 cores in the CPU. The CPU has 16 threads and can simulate up to 16 cores. The core of the CPU is the arithmetic unit and the controller. Multi-cores can enhance parallel processing capabilities. A thread is a single sequence of control flow in a process. Running multiple threads at the same time to complete different tasks in a single program is called multi-threading.

What does 12 cores and 16 threads mean?

12 cores and 16 threads means that there are 12 cores in the CPU and 16 threads in the CPU. Up to 16 cores can be simulated.

The core of the CPU

The core of the CPU is the arithmetic unit and controller. Multi-core CPUs can enhance parallel processing capabilities and can process multiple threads at one time. Several cores are integrated on one CPU. Single-core means just one, dual-core puts two cores on top of the CPU, and so on.

The number of cores in a CPU refers to how many physical cores it has inside. Each core can be treated as a single-core CPU. A dual-core CPU is equivalent to having two sets of hardware resources combined in one box.

Thread

A thread is a single sequence of control flow in a "process". Also known as lightweight process. A thread is a single sequential flow of control in a program. Running multiple threads at the same time to complete different tasks in a single program is called multithreading.

The number of threads a CPU has originally corresponds to the number of cores, that is, the number of threads a CPU has as many cores as it has. However, Intel released a hyper-threading technology in 2002, which uses a special Hardware instructions simulate one CPU core into two logical cores, so that when processing some multi-threaded tasks, parallel processing of data can be achieved, greatly improving computing efficiency, and making the performance of the CPU more thorough. But the simulated core is not a real physical core after all, and the overall performance is still not as good as a real multi-core CPU.
