− | A larger number of sensors across the entire die are used to measure many of the CPU states including [[frequency]], [[voltage]], [[power]], and [[temperature]]. The data is in turn used for workload characterization, [[adaptive voltage]], frequency tuning, and [[dynamic clocking]]. [[Adaptive voltage and frequency scaling]] (AVFS), an on-die closed-loop system that adjusts the voltage in real time following real-time measurements based on sensory data collected | + | A larger number of sensors across the entire die are used to measure many of the CPU states including [[frequency]], [[voltage]], [[power]], and [[temperature]].

Zen implements over 1300 sensors to monitor the state of the die over all [[critical paths]] including the CCX and external components such as the memory fabric. Additionally the CCX also incorporates 48 high-speed power supply monitors, 20 [[thermal diodes]], and 9 high-speed droop detectors. | Zen implements over 1300 sensors to monitor the state of the die over all [[critical paths]] including the CCX and external components such as the memory fabric.
