What Is Scalable Link Interface (SLI)?

The technology behind Scalable Link Interface, or SLI, is a little like the three-legged person in that old nursery rhyme. It's not like anything else, and it's pretty amazing. SLI is a technology that allows you to use multiple graphics cards working together to produce a single output. It is an application of the concept of parallel processing, which dramatically increases the performance of graphic-intensive applications like games and 3D rendering. SLI enables multiple graphic processing units (GPUs) to work together to make processing faster and share the workload in rendering a scene. You might wonder how SLI works or if it's worth buying a second graphics card. Well, we're here to answer your questions! An SLI setup splits a scene into two sections and assigns each GPU a unique portion. The master portion is always in the top half, while the enslaved person is always in the bottom. When the enslaved person has finished rendering the other half of the scene, it is combined with the master portion and sent to the display. It means that each GPU works on different parts of a single picture. By splitting up this workload, each card can render its portion faster than if they were trying to simultaneously work on an entire image. So you get better performance for less money! Graphics card technology has been advancing at a breakneck pace, but the demand for even more power is growing faster. So what can we do? The good news is that you don't have to wait for new technologies to be developed—we've already figured out how to harness multiple GPUs and make them work together! SLI is a way of using various graphics cards in parallel processing to make your computer run faster. With SLI, you can get up to twice as much performance from your computer for the same price as a single graphics card—so it's like getting twice as much for half the cost!
