CPU with multithreading support

Multi-threading

— support for multi-threading by the processor.

For Intel it's Hyper-threading, for AMD it's SMT. This technology is used to optimize the load on each physical processor core. Its key principle (simplified) is that each such core is defined by the system as 2 logical cores – for example, the system "sees" a quad-core processor as an eight-core one. At the same time, each physical core constantly switches between two logical cores, in fact – between two threads of commands: when a delay occurs in one thread (for example, in case of an error or while waiting for the result of the previous instruction), the core does not idle, but starts executing the second thread commands. Thanks to this technology, the response time of the processor is reduced, and in server systems, stability is increased with a large number of connected users.
