These sensors were officially introduced in AMD K8 Revision F processors, and provide 0.5 degC accuracy. Precision was improved in Revision G chips, which provide two more bits for 0.25 degC steppings. Each core has two temperature sensors, and there are up to two cores per CPU socket.
AMD Barcelona, AMD Phenom, and AMD Griffin provide 0.125 degC accuracy and provide one temperature sensor for each CPU socket.
The amdtemp driver reports temperatures through the envsys(4) API.
