NVIDIA Introduces Hybrid SLI

NVIDIA introduced its new Hybrid SLI technology for motherboards. These new platforms are the foundation for a new breed of PCs that deliver a richer visual experience while reducing energy consumption and costs, fan noise, and even heat. The new technology is available immediately with new NVIDIA nForce 780a SLI and GeForce 8 Series based motherboards.

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’s visually intensive applications and home entertainment.

The Hybrid SLI-enabled desktop PC motherboards are designed to create a balanced PC with GeForce GPUs and AMD Phenom processors. Eight models, including a newly available nForce 780a SLI motherboard, are available:

• nForce 780a SLI, nForce 750a SLI, nForce 730a, and nForce 720a
• GeForce 8300, GeForce 8200, and GeForce 8100

Currently available Hybrid SLI-enabled discrete graphics cards include:

• NVIDIA GeForce 9800 GX2 and NVIDIA GeForce 9800 GTX (both HybridPower-capable)
• GeForce 8400 GS and GeForce 8500 GT (both GeForce Boost-capable)

Hybrid SLI-enabled PC motherboards for Intel processors and Hybrid SLI-enabled notebooks will be available in Q3 of 2008.
