Intel Hyper-Threading
Intel Hyper-Threading is a technology that allows a single physical CPU core to execute multiple threads simultaneously. This is achieved by duplicating certain hardware resources within the core, such as the instruction fetch and decode unit, the register file, and the execution units. Each physical core with Hyper-Threading enabled appears to the operating system as two logical cores, each with its own instruction pointer and set of registers.
By allowing multiple threads to run on a single core, Hyper-Threading can improve performance for applications that are heavily multithreaded. This is because the multiple threads can share the core’s resources, such as the cache and TLB, which can reduce the overhead of context switching between threads.
Hyper-Threading can provide a significant performance boost for applications that are able to take advantage of it. However, it is important to note that not all applications will benefit from Hyper-Threading. Applications that are designed to run on a single core may not see any benefit from Hyper-Threading, and in some cases, Hyper-Threading can actually hurt performance.
