Featuring single- and multithreaded execution, the Power5 provides higher performance in the single-threaded mode than its Power4 predecessor at equivalent frequencies. Enhancements include dynamic resource balancing to efficiently allocate system resources to each thread, software-controlled thread prioritization, and dynamic power management to reduce power consumption without affecting performance.
