ThrottleWatch™ 2.0
ThrottleWatch™ is a Windows utility for detecting and reporting CPU throttling activity in Pentium 4, Xeon, Pentium M, and Athlon 64 processors. New version 2.0 also graphs (and optionally logs) fluctuations in the CPU's core frequency and core voltage made by Intel SpeedStep™ Technology, Intel Enhanced SpeedStep™ Technology, and AMD Cool‘n’Quiet™ Technology.
What is Thermal Management Throttling?
Thermal Management Throttling is designed to protect the processor from failure due to overheating.
When triggered by the CPU's internal temperature sensor, Thermal Management Throttling attempts to reduce the temperature of the CPU core. It can do this in two different methods, referred to as TM1 and TM2: by inserting idle processing cycles in the CPU's instruction pipeline (TM1), or by reducing the internal clock frequency of the CPU (TM2).
ThrottleWatch™ monitors and graphically displays both the CPU load level and any Thermal Management Throttling that occurs. In the example at left, the top bar graph and histogram show the CPU load. The bottom bar graph and histogram (in red) show Thermal Management throttling activity.
What is Power Management Throttling?
Power Management Throttling is a technique of dynamically lowering the CPU's core speed and voltage during intervals of low system load, with the goal of reducing power consumption and extending battery life and/or lowering fan noise. In the screenshot at left, the top graph displays the CPU load; the middle graph shows the CPU frequency, and the bottom graph shows the CPU core voltage. Note that in periods of higher CPU load, the CPU frequency and core voltage increase.
Power Management Throttling is a feature of Intel Pentium M, Mobile Intel Pentium 4 Processor (Prescott core), and AMD Athlon64 processors.
