Delivering Potent Portable Graphics With Power to Spare

With the revolutionary graphics power of NVIDIA mobile graphics processing units (GPUs) empowering high-end 3D and 2D applications on notebook PCs and mobile workstations, professionals and end users on the go expect maximum performance and the longest possible battery life from their favorite mobile platform.

However, having a notebook equipped with the fastest mobile 3D GPU doesn’t mean that users have to compromise 3D performance for battery life. In fact, notebook battery consumption relates to the entire computer system and not just a single individual subsystem or component. In reality, the graphics subsystem actually consumes far less power than three of the most major offenders: the CPU, the LCD, and the power supply. NVIDIA developed PowerMizer™ technology, an integral part of its mobile families of GPUs, to give end users the ability to adjust the notebook’s level of battery consumption according to their own priorities: maximum performance or longer battery life.

What is PowerMizer?

PowerMizer is a dynamic power-modulation technology, allowing notebook users to adjust system performance and battery consumption to their specific needs. For some users, consistently high frame rates in their favorite game or workstation application is a must; for others, such as frequent travelers on transatlantic flights, the longest possible battery life is a necessity.

PowerMizer offers a number of settings for maximum flexibility:

Its maximum performance setting is ideal for notebook gamers and professionals utilizing workstation applications. PowerMizer also has AC-detect, switching to maximum performance mode whenever you are plugged into the wall outlet.
For PowerPoint users or anyone requiring a combination of 3D performance and long battery life, PowerMizer offers a mid-range setting.
And, for users on long flights who may need to extend battery life to prepare a spreadsheet or document or watch a DVD double-bill, PowerMizer offers a setting for the longest battery life.

How Does PowerMizer Work?
PowerMizer’s evolving architecture allows for both automatic and end-user control of performance and power. Operating at an industry-low 1.575 volts, NVIDIA's mobile GPUs incorporate PowerMizer technology to conserve battery life, while offering optimal performance. In addition, computationally-intense geometry calculations such as hardware transform and lighting are offloaded from the CPU to the GPU to provide superior performance while using minimal system power; allowing efficient dual pixel pipelines to render scenes faster and spend less time running at full power.

From maximum 3D performance to longer battery life, PowerMizer gives notebook users a full range of system power control. By working with NVIDIA’s revolutionary graphics hardware, which offloads functions from the CPU onto the GPU, PowerMizer effectively controls system power consumption while maintaining stunning 3D graphics performance.

With the GeForce FX Go series of GPUs, NVIDIA introduces PowerMizer 3.0, delivering numerous mobile power management innovations, including:

The NVIDIA CineFX engine is dedicated hardware that greatly offloads the graphics workload from the CPU, improving performance and thermal budgets, extending battery life, and contributing to the rendering of cinematic-quality graphics.
New hardware MPEG-2 decode engine establishes a new record for low CPU utilization, enabling long battery life for DVD playback.
NVIDIA Intellisample technology reduces the required raw memory bandwidth/power for graphics processing, without compromising graphics quality.
The industry’s lowest voltage operation using the latest 0.13 micron process technology, running down to 1.0 volt.
Advanced power management technology continuously monitors notebook processes and dynamically controls system power utilization, ensuring that valuable energy is not wasted on idle processes—thus seamlessly extending battery life.
