Hybrid SLI Announced

January 8th, 2008
At CES NVIDIA has announced Hybrid SLI, a new technology that aims to increase graphics performance as well as reduce power consumption. The new technology will be incorporated into a wide variety of graphics and motherboard desktop and notebook products for both AMD and Intel processors. Though no release date was offered, it was stated that this technology will make it to computers this year.

“From the introduction of programmable GPUs to the rapid adoption of our multi-GPU SLI technology, NVIDIA has repeatedly pioneered and innovated to solve difficult problems for the industry. We believe Hybrid SLI technology is one of the most important innovations we’ve come up with to date,” said Jen-Hsun Huang, CEO of NVIDIA. “Hybrid SLI delivers new multi-GPU technology to a large segment of the PC market, delivering consumers a level of PC graphics performance and power efficiency never before seen.”

Hybrid SLI basically enables motherboard GPUs to work cooperatively with discrete graphics card. GeForce Boost allows the PC to boast higher graphical prowess, while HybridPower lets the computer use more power when needed, or transition to a lower-powered operating state when not. Here’s more:

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 horsepower 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. When a game or application is started that requires the additional 3D horsepower, the PC can automatically transition back to the discrete graphics cards and power up the 3D capabilities all transparent to the end useri.

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.
