NVIDIA Hybrid SLI introduction

The visual capabilities of typical PCs are driven by either integrated graphics on the motherboard or by higher performance, discrete graphics cards. Unfortunately, the most common integrated graphics chips lack the performance and features needed by many popular modern 3D applications, games, and movies. Discrete graphics cards deliver a far superior visual experience, but consume more energy.

According to the press release, Hybrid SLI-enabled motherboards eliminate this problem by putting a GeForce GPU directly on the motherboard. This GeForce GPU has better DirectX compatibility and HD movie playback capability than the most common integrated graphics chips found in today's PCs, but consumes less energy than a discrete graphics card.

Designed for PC enthusiasts and hard-core gamers, the HybridPower feature completely powers down the discrete graphics cards and switches graphics processing to the motherboard GPU in applications where major 3D horsepower is not required, such as e-mail and Web surfing. Users will appreciate the lower energy consumption, quieter PC operation, and less heat. When additional 3D horsepower is needed, it can be manually transitioned back to discrete graphics cards using HybridPower technology, which are then powered up and ready to rock the 3D world. Hybrid SLI technology allows to save on energy costs over the life of the PC for high-end, enthusiast-class PCs, and deliver additional graphics performance for more mainstream desktops via these two features.

For mainstream users, a Hybrid SLI technology feature called GeForce Boost allows the user to add an additional graphics card for even more graphics horsepower. By combining the performance of the motherboard GPU and graphics card discrete GPUs, GeForce Boost increases overall graphics performance up to 50% for today
