AMD has announced 550MHz and 533MHz versions of its Mobile AMD-K6-2+ family of processors featuring a new power management technology called “PowerNow!” AMD claims its new PowerNow! technology can extend the battery life of notebook systems by up to 30%.
PowerNow! is AMD's second generation of power management technology. It includes a unique “automatic” mode that optimizes power consumption transparently, rather than requiring the user to manually select a performance or battery saving mode. PowerNow! technology is a combination of software and hardware support that allows the processor to run at different frequencies and voltages. There are three basic modes of operation, including AMD's unique “automatic” mode:
- High Performance mode — the CPU runs at maximum frequency and voltage
- Battery Saver Mode — the CPU runs at lowest frequency and voltage to maximize system battery life
- Automatic Mode — the system monitors application usage and continuously varies operating frequency and voltage to deliver performance on demand while optimizing battery life
The Mobile AMD-K6-2+ processor is offered in speeds of 550MHz, 533MHz, 500MHz, 475MHz and 450MHz. The processor incorporates a 128Kbyte on-chip, Level 2 cache, support for AMD PowerNow! technology, an enhanced implementation of AMD's 3DNow! instruction set with digital signal processing (DSP) instructions, and a 100MHz front-side bus.
Mobile AMD-K6-2+ processors operate at a core voltage of 1.4 to 2.0 Volts, have an extended case temperature rating of 85 degrees Celsius, and dissipate as little as 3 Watts of power running in PowerNow! battery-saver mode of operation. The processors are available in Socket 7/Super7(tm) platform-compatible 321-pin Ceramic Pin Grid Array packages.
