The world of computer hardware is constantly evolving, with new technologies emerging and old ones becoming obsolete. One technology that has been around for a while is SLI (Scalable Link Interface), a multi-GPU (Graphics Processing Unit) technology developed by NVIDIA. In recent years, there has been a lot of speculation about the future of SLI, with many people wondering if it’s still relevant or if it’s been deprecated. In this article, we’ll explore the history of SLI, its current state, and what the future holds for this technology.
A Brief History of SLI
SLI was first introduced by NVIDIA in 2004 as a way to increase the performance of graphics cards. The idea behind SLI was to allow multiple graphics cards to work together, sharing the workload and increasing overall performance. This was achieved by using a special bridge to connect the graphics cards, allowing them to communicate with each other and divide the workload.
In the early days of SLI, the technology was limited to high-end graphics cards and was mainly used by gamers and professionals who needed extreme graphics performance. However, as the technology improved and became more widely available, SLI became a popular choice for many PC enthusiasts.
How SLI Works
SLI works by using a technique called alternate frame rendering (AFR), where each graphics card renders a different frame. This allows the workload to be divided between the graphics cards, increasing overall performance. The SLI bridge is used to connect the graphics cards and allow them to communicate with each other.
There are several different types of SLI configurations, including:
- 2-way SLI: This is the most common configuration, where two graphics cards are connected using an SLI bridge.
- 3-way SLI: This configuration uses three graphics cards, which are connected using two SLI bridges.
- 4-way SLI: This is the most extreme configuration, where four graphics cards are connected using three SLI bridges.
The Current State of SLI
In recent years, the popularity of SLI has declined, and many people have begun to wonder if it’s still relevant. There are several reasons for this decline, including:
- Increased single-GPU performance: Modern graphics cards have become incredibly powerful, making it less necessary to use multiple graphics cards to achieve high performance.
- Rise of alternative technologies: Other technologies, such as NVIDIA’s DLSS (Deep Learning Super Sampling) and AMD’s multi-frame sampled anti-aliasing (MFAA), have emerged as alternatives to SLI.
- Cost and complexity: SLI configurations can be expensive and complex to set up, which has made them less appealing to many users.
Despite these challenges, SLI is still supported by NVIDIA and can be used with many modern graphics cards. However, the company has begun to shift its focus towards other technologies, such as DLSS and ray tracing.
SLI in Modern Systems
While SLI may not be as popular as it once was, it can still be used in modern systems to increase graphics performance. However, there are several things to consider before setting up an SLI configuration:
- Graphics card compatibility: Not all graphics cards are compatible with SLI, so it’s essential to check the specifications before purchasing.
- Motherboard support: The motherboard must also support SLI, which can be a limiting factor for some users.
- Power supply requirements: SLI configurations require a powerful power supply, which can add to the overall cost.
SLI in Gaming
SLI can still be beneficial for gamers who want to achieve high frame rates and resolutions. However, the benefits of SLI will vary depending on the game and the graphics cards used. Some games are optimized for SLI, while others may not see a significant performance increase.
SLI in Professional Applications
SLI can also be used in professional applications, such as video editing and 3D modeling. In these applications, SLI can help to increase performance and reduce rendering times.
The Future of SLI
While SLI may not be as popular as it once was, it’s still a viable option for users who need extreme graphics performance. However, the future of SLI is uncertain, and it’s possible that the technology may eventually be phased out in favor of alternative technologies.
NVIDIA has already begun to shift its focus towards other technologies, such as DLSS and ray tracing. These technologies offer many of the same benefits as SLI, but without the need for multiple graphics cards.
Alternatives to SLI
There are several alternatives to SLI that have emerged in recent years, including:
- NVIDIA DLSS: This technology uses deep learning to improve graphics performance, reducing the need for multiple graphics cards.
- AMD MFAA: This technology uses multiple frames to improve anti-aliasing, reducing the need for multiple graphics cards.

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 be linked together in a single system. This allows for increased graphics processing power, improved performance, and enhanced gaming experiences. SLI works by dividing the workload between the multiple GPUs, with each GPU rendering a portion of the graphics frame.
In an SLI setup, the system’s motherboard must support SLI, and the GPUs must be identical or very similar in terms of model and memory configuration. The SLI technology then handles the distribution of the workload between the GPUs, ensuring that the graphics are rendered efficiently and effectively. This can result in significant performance gains, especially in applications that are heavily dependent on graphics processing power.
Is SLI still relevant in modern gaming?
While SLI is still supported by some modern games, its relevance has decreased in recent years. Many modern games are designed to take advantage of single, powerful GPUs rather than multiple GPUs in SLI. This is due in part to the increasing power and efficiency of single GPUs, as well as the rise of alternative technologies such as NVIDIA’s DLSS (Deep Learning Super Sampling).
However, SLI can still be beneficial in certain situations, such as in games that are heavily dependent on graphics processing power or in applications that require extreme levels of performance. Additionally, some games may still be optimized for SLI, in which case an SLI setup can provide significant performance gains. It’s essential to research the specific game or application to determine whether SLI is still relevant and beneficial.
What are the limitations of SLI?
One of the primary limitations of SLI is the requirement for identical or very similar GPUs. This can make it difficult to upgrade an SLI setup, as the new GPU must match the existing one. Additionally, SLI requires a compatible motherboard, which can add to the overall cost of the system.
Another limitation of SLI is the potential for micro-stuttering, which can occur when the GPUs are not perfectly synchronized. This can result in a less-than-smooth gaming experience, even if the frame rates are high. Finally, SLI can also be limited by the game or application itself, as not all software is optimized to take advantage of multiple GPUs.
Is SLI deprecated?
While NVIDIA has not officially deprecated SLI, the company has shifted its focus towards other technologies, such as DLSS and ray tracing. As a result, SLI is no longer the flagship technology it once was, and support for it may be limited in future drivers and software releases.
That being said, SLI is still supported by many modern NVIDIA GPUs, and it can still be used to improve performance in certain situations. However, users should be aware that SLI may not be as widely supported or optimized as it once was, and alternative technologies may offer better performance and efficiency.
What is the difference between SLI and NVLink?
SLI and NVLink are both technologies developed by NVIDIA for linking multiple GPUs together. However, they serve different purposes and offer different benefits. SLI is primarily designed for gaming and graphics applications, where it can be used to improve performance and increase frame rates.
NVLink, on the other hand, is a more general-purpose technology that can be used for a wide range of applications, including artificial intelligence, deep learning, and professional visualization. NVLink offers higher bandwidth and lower latency than SLI, making it better suited for applications that require extreme levels of performance and data transfer.
Can I use SLI with AMD GPUs?
No, SLI is a proprietary technology developed by NVIDIA, and it is only compatible with NVIDIA GPUs. AMD has its own multi-GPU technology, known as Crossfire, which is designed to work with AMD GPUs.
Crossfire is similar to SLI in that it allows multiple GPUs to be linked together to improve performance. However, it is not compatible with NVIDIA GPUs, and it requires a compatible motherboard and software support. While Crossfire is still supported by some modern AMD GPUs, its relevance has also decreased in recent years, similar to SLI.
How do I know if a game supports SLI?
The best way to determine if a game supports SLI is to check the game’s documentation or website. Many game developers will explicitly state whether their game supports SLI, and some may even provide detailed instructions on how to enable it.
Alternatively, you can also check the NVIDIA website, which maintains a list of SLI-supported games. You can also check online forums and communities, where users may share their experiences and tips for enabling SLI in specific games. Keep in mind that even if a game supports SLI, it may not always work perfectly, and some tweaking may be required to get the best results.
