However, if hyper-threading is in use, the replay system will prevent the other thread from utilizing the execution units. This is the true cause of any performance degradation concerning hyper-threading. In Prescott, the Pentium 4 gained a replay queue, which reduces the time the replay system will occupy the execution units. [2]
