NVIDIA's hybrid technology balances PC performance and power consumption

January 12, 2008 NVIDIA has announced the industry’s first hybrid technology for PC platforms that increases graphics performance and reduces power consumption. NVIDIA Hybrid SLI technology is based on the Company’s GeForce graphics processor units (GPUs) and SLI multi-GPU technology and enables NVIDIA motherboard GPUs (mGPUs) to work cooperatively with discrete NVIDIA GPUs (dGPUs) when paired in the same PC platform. Hybrid SLI provides two new technologies - GeForce Boost and HybridPower - that allow the PC to deliver graphics performance for today’s applications and games when 3D graphics horsepower is required, or transition to a lower-powered operating state when not. For lower energy consumption and quieter PC operation, HybridPower allows the PC to switch processing from a single GPU or multiple GPUs in SLI configuration to the onboard motherboard GPU.
HybridPower is most useful in situations where graphics grunt is not required, such as high definition movie playback on a notebook platform or simple e-mail or Internet browsing on a desktop. It is also beneficial for those users who want a quiet operating state with reduced thermals and noise. For notebooks, HybridPower can also dramatically extend battery life by up to 3 hours and when a game or application is started that requires the additional 3D horsepower, the system can automatically transition back to the discrete graphics cards and power up the 3D capabilities all transparent to the end user. For applications where 3D performance is required, GeForce Boost turbo-charges 3D operation by combining the processing power of the traditional NVIDIA GeForce-based graphics card with that of the second GPU integrated into the motherboard core logic. In media-rich applications, both GPUs work in tandem to render the combined images with the end user benefiting from the increase in performance and frame rate. For typical games and 3D applications, GeForce Boost can kick in automatically, resulting in a greatly enhanced consumer experience.
NVIDIA will incorporate Hybrid SLI technology into a wide variety of graphics and motherboard desktop and notebook products that the company is rolling out for both AMD and Intel desktop and notebook computing platforms throughout 2008, including the upcoming NVIDIA nForce 780a SLI, nForce 750a SLI, and nForce 730a media and communication processors (MCPs) for AMD CPUs, which will be released next month, as well as the new GeForce 8200 - the industry’s first micro-ATX motherboard solution with an onboard Microsoft DirectX 10-compliant motherboard GPU. NVIDIA Hybrid SLI notebooks as well as desktop products designed for Intel CPUs will be available next quarter.
