Why Nvidia and AMD Are Dropping SLI and Crossfire in Favor of Single-GPU Performance
Nvidia and AMD, the two leading manufacturers in the graphics card market, have been moving away from SLI (Scalable Link Interface) and Crossfire (AMD’s multi-GPU technology) respectively. This shift is driven by several factors, including diminishing returns, complexity in development, focus on single-GPU performance, power and thermal issues, and emerging technologies.
Diminishing Returns
The performance gains from using multiple GPUs have become less significant with more recent games and applications. Many titles do not scale well with multiple graphics cards, leading to inconsistent performance and a disappointing user experience. This diminishing marginal return on investment for multi-GPU setups has made it less appealing for both consumers and manufacturers.
Complexity in Development
Game developers face significant challenges when optimizing their titles for multi-GPU setups. As a result, many games do not support SLI or Crossfire, which reduces the incentive for users to invest in multiple GPUs. This lack of support further widens the gap between single-GPU and multi-GPU performance, making multi-GPU setups less attractive.
Increased Focus on Single-GPU Performance
Both Nvidia and AMD have shifted their focus towards enhancing the performance of single GPUs. With advancements in single-GPU technology, users can achieve high performance with a single powerful graphics card, eliminating the need to rely on multiple cards. This shift not only simplifies the user experience but also provides a more efficient and cost-effective solution.
Power and Thermal Issues
Using multiple GPUs increases power consumption and heat output, leading to thermal throttling and other issues. These factors make multi-GPU setups less appealing for consumers who are concerned about energy efficiency and system noise. Companies are now prioritizing the development of single-GPU cards that provide similar or better performance with lower power consumption and improved thermal management.
Emerging Technologies
Technologies like ray tracing and AI-driven graphics enhancements, such as Nvidia’s DLSS (Deep Learning Super Sampling), have shifted the focus towards maximizing the capabilities of individual GPUs rather than combining them. These advanced features require powerful single-GPU hardware and provide significant performance improvements, making multi-GPU setups less necessary for optimal gaming experiences.
Market Trends
There has been a general trend towards more efficient and powerful single GPUs in the market. Consumers now prefer to upgrade to a single high-end card rather than investing in multi-GPU setups. This shift in market preference is driving the trend towards single-GPU technology, as companies must adapt to meet the evolving needs of consumers.
For these reasons, Nvidia and AMD have been de-emphasizing SLI and Crossfire, focusing instead on enhancing the capabilities of their single-GPU offerings. While some crossfire setups can achieve near-perfect 100% scaling in certain games, the overall trend is towards single-GPU performance for the majority of users. This shift not only simplifies the user experience but also provides a more cost-effective and efficient solution for modern gaming requirements.
