What is nvidia sli

In addition, unique software algorithms efficiently share the workload to deliver unbelievable performance. This bridge provides the necessary high-speed data path required for the graphics processing units to operate in tandem, providing up to two times the graphics performance of non-SLI enabled systems.

Figure 1: Two GPUs on a single card Now, Alienware leverages a revolutionary approach to combine multiple GPUs in a single system to enable screaming, boundless performance.

It is possible to mix cards from different manufacturers as long as the same GPU is used in both cards, but it is always recommended to use identical video cards for SLI configurations.

The presence of a SLI bridge connector is highly recommended, and in some configurations its presence is mandatory. Table of Contents Show. A friend of mine fried his motherboard thinking that, as he had enough slots, he could insert graphics cards and simply boot up the computer. Okay, that was me.

Still, there are a few more requirements than just a couple of available PCI-Express x16 slots. First, you need to check if the motherboard is SLI compatible. This is a really vital step, so be careful, particularly as some motherboards support SLI, others CrossFire, some both, or neither.

Secondly, you need identical graphics cards. They need to be the same model and series , although it is possible to get them from different manufacturers. In a two-card setup, the master will work on the upper part of the screen , while the slave will manage the bottom part. Once the slave has rendered its part of the screen, it sends it to the master, which then combines the two renders and outputs to the monitor.

In those rare cases where the cards are mismatched, the slower or lesser card will become dominant, with the better card adjusting by either running at the same speed as the other card or disabling its extra memory. SLI Bridge connects the graphics cards. This is also possible for high-end cards , though not recommended. This is where SLI Bridge is useful because it reduces the bandwidth constraints and can transfer data directly between the cards.

While the two-GPU setup is likely the most popular one, SLI can also be configured in a three or four GPU dynamic by either using a single bridge that connects every card or by combining two two-way bridges. The future is uncertain for these layouts as NVIDIA is phasing out its support for more than two-card combinations due to high driver complexity. A very powerful and reliable Power Supply Unit is necessary as the GPUs are big power consumers and you will be running two or more simultaneously.

High-end graphics cards can use up to watts of power so be aware of this as well. Important: Not all games and applications support SLI. To achieve this, the frame is split on a horizontal line, depending on geometry.
