Final answer:
NVIDIA's method for connecting multiple video cards is called SLI (Scalable Link Interface), enhancing performance by dividing the workload. It requires an SLI-compatible motherboard, special graphics cards, and a bridge connector. The technology enables leveraging the combined power of multiple GPU cores.
Step-by-step explanation:
NVIDIA's method of connecting multiple video cards in the same system is called SLI, which stands for Scalable Link Interface. This technology allows two or more graphics cards to share the workload of rendering graphics, which can significantly increase performance in graphics-intensive tasks such as gaming or 3D rendering. To use SLI, you need a compatible motherboard that supports the SLI configuration, SLI-ready graphics cards, and a bridge connector to link the cards together. By pooling the resources of processing cores typically found across multiple graphics units, SLI can deliver enhanced graphics performance and improve the overall gaming experience.
It is important to note that other methods and technologies exist for connecting multiple video cards, such as AMD's CrossFire, and that technological advancements are constantly made, leading to newer solutions. Moreover, not all software can utilize the full potential of SLI configurations, as program support for parallel processing is a related keyword in understanding the effectiveness of such setups.
