What Is Hyperthreading?
If an operating system sees more cores than existing physical cores, that is the effect of hyperthreading. CPUs have the capability to signal each core to emulate two or more processors. These emulated processors are called threads. Each of these emulated processors can execute multiple queues of instructions, by means of a time-sharing resource (clever multitasking techniques) and increase the efficiency and throughput of a CPU. Figure 13-4 shows a graphical representation of hyperthreading.
