What is AMD PowerNow! Technology
3
24404A/0—November 2000
AMD PowerNow! Technology Dynamically Manages Power and Performance
Preliminary Information
Operating Modes
Along with the finest granularity of control in the industry,
AMD PowerNow! technology supports different modes of
operation.
I
In
High-Performance mode
, the processor runs at the
maximum rated voltage and speed providing the maximum
performance possible.
Changing to
Power-Saver mode
configures the processor to
run at the lowest voltage and frequency supported for the
most efficient power profile.
In
Automatic mode
, the speed and voltage are dynamically
and automatically determined by actual performance
demands of the application.
In Automatic mode, the needs of
the
application
environment
performance required and power used
. This mode of operation
ensures that only the required amount of power is dissipated
to meet the performance demands of the application.

These features are possible through the modifications made in
the AMD-K6 processor core. They include an integrated CPU
clock speed control and additional pins to control an off-the-
shelf programmable voltage regulator. None of these features
requires changing any external bus frequencies, thereby
maintaining overall integrity of the system and reducing the
possibility of complications.
Key Features
I
Supported on all AMD-K6-2E+ and AMD-K6-IIIE+ low-power
processors.
Up to 32 allowable core voltages driven by Voltage
Identification (VID) pins.
25 and 50 mV core voltage steps for the finest control.
Scalable frequency control from a low of 133 or 200 MHz
with steps of 33 or 50 MHz.
Voltage and frequency are independently configurable.
Automatic mode support for precise and errorless power and
performance scaling.
