A technique of running multiple threads on a CPU so that the CPU doesn't stall when waiting for data from memory.

Intel technology that allows processors in the 3GHz and faster range work on two separate threads of data at the same time. Software needs to be optimized for hyperthreading in order for users to see improved performance.

A technique used in some Intel CPUs to enable software to treat the CPU as two processors to complete processing more quickly.

See simultaneous multithreading.
