What is SLI and how does it work?

SLI, or Scalable Link Interface, is a technology developed by NVIDIA that allows multiple graphics processing units (GPUs) to work together in a single system. This technology enables the GPUs to share the workload, increasing the overall graphics processing power and improving performance in graphics-intensive applications such as gaming and video editing. SLI works by connecting multiple GPUs together using a bridge or a high-speed interconnect, allowing them to communicate and coordinate their efforts.

In an SLI setup, one GPU is designated as the primary GPU, while the others are secondary GPUs. The primary GPU handles the majority of the graphics processing, while the secondary GPUs assist with tasks such as physics simulations, texture rendering, and other compute-intensive tasks. By distributing the workload across multiple GPUs, SLI can significantly improve performance and reduce the time it takes to render complex graphics.

Why did SLI technology decline in popularity?

SLI technology was popular in the mid to late 2000s, but its popularity declined in the following years due to several factors.
