The Graphics Processing Unit (GPU) is a crucial component in any PC build. It serves as the powerhouse behind everything you see on your monitor, whether it’s gaming, streaming, design, or simply browsing. Depending on your needs, you may opt for a built-in GPU that comes with your Central Processing Unit (CPU) or a dedicated Graphics Card (also known as Discrete graphics or Discrete GPUs). Some PC builders may even consider multiple discrete GPUs for power-intensive tasks, leading them to research and create a GPU workstation build. Discover the importance of GPUs and how they enhance your PC experience.
Unfortunately, explaining the answer to entry-level builders can be quite challenging. In light of this, it’s best to advise them to steer clear. Adding multiple GPUs to your system increases complexity and raises the likelihood of troubleshooting and repair issues before even launching your first game. Furthermore, even if a PC builder manages to overcome the complexity of installing multiple GPUs, they often won’t experience significant performance gains with most applications.
While a multi-GPU build can be worthwhile, it’s important to understand what you’re doing to ensure success. In my posts, I’ll equip you with the knowledge needed to make an informed decision about building a GPU workstation. Whether it aligns with your workload or gaming needs, you’ll be able to decide if it’s the right choice for you.
The Challenges of Multiple Graphics Cards
Software Functionality
Before diving into the details of setting up a GPU workstation, it’s crucial to determine if it will truly benefit you. The key factor to consider is the software you intend to run. While a multi-GPU setup can significantly enhance performance, the actual benefit largely depends on the specific applications and games you plan to use. Discover if a GPU workstation is right for you and maximize your performance potential.
Not all software is optimized for multi-GPU technology like SLI or CrossFire, which divides tasks between multiple GPUs. To achieve effective performance, the software must support multi-GPU scaling.
Certain games and professional applications boast outstanding multi-GPU scaling, harnessing the added power of a second or third GPU effectively. However, not all programs support multi-GPU scaling, rendering a second GPU useless in terms of performance enhancement.
In addition, the scalability of multi-GPU setups can differ across programs. While some may experience a significant performance boost by adding a second GPU, others might only see a minor improvement in performance.
Before you invest in a multi-GPU setup, it’s important to research the level of support for multiple GPUs in the games or applications you use most frequently. If the software you use doesn’t scale well with multiple GPUs, it may be more beneficial to invest in a single, more powerful GPU instead. Make an informed decision that suits your needs and maximizes performance.
Hardware and Firmware Compatibility Obstacles
When setting up your multi-GPU system, one of the initial challenges is finding compatible combinations of graphics cards and motherboards that support multiple GPUs. This crucial step often disappoints builders hoping to extend the life of their old cards by pairing them with cheaper alternatives. However, it’s important to note that both the graphics cards and the motherboard must support multi-GPU functionality and be compatible with each other. Failure to meet these requirements can result in compatibility issues that may hinder system performance.
When it comes to multi-GPU setups, you’ll primarily encounter two types: SLI and CrossFire. SLI, developed by NVIDIA, and CrossFire, developed by AMD, are technologies that enable multiple graphics cards of the same or similar model to work together. This collaboration effectively distributes the workload of rendering graphics.
However, there are some important factors to consider. Firstly, it is crucial that your motherboard supports either SLI or Crossfire, and that your graphics cards are compatible with the same technology as your motherboard. Additionally, you might have observed that the graphics cards should be of the same or a similar model. Ensuring these requirements are met will greatly enhance your system’s performance and compatibility.
In the past, it was possible to combine different GPUs, including integrated and discrete ones, for SLI or Crossfire. However, the compatibility landscape has changed, and now it is crucial to use the same model for all cards.
In some cases, you can still achieve compatibility within the same GPU model family. For instance, pairing an RTX 2070 with an RTX 2080, both part of the RTX 20 series, is possible. However, it’s important to note that the more powerful card may experience performance loss as it adapts to the settings of the lower model. This means that the RTX 2080 would be “downgraded” to match the performance of the RTX 2070.
Nevertheless, not all GPUs supporting Crossfire or SLI allow for pairing with another card. Therefore, it is crucial to thoroughly check compatibility if you wish to explore options beyond the norm. Keep in mind that extensive research might make you feel like Charlie Kelly explaining conspiracy theories.
Reaping the Rewards of Multiple Graphics Cards
Multi-GPU setups offer numerous benefits, making them a worthwhile investment. One of the most notable advantages is the potential for improved performance. By distributing the workload across multiple GPUs, you can effectively double or even triple your graphical processing power, resulting in smoother and faster performance for applications that support multi-GPU configurations.
In addition to enhanced performance, multi-GPU setups allow for higher-quality textures and more immersive visual effects, enhancing your gaming and application experience. Furthermore, these setups can help reduce the occurrence of “screen tearing,” where the display shows information from multiple frames in a single screen draw.
Investing in a multi-GPU setup also future-proofs your PC. As games and applications become more advanced, they require greater graphical processing power. With multiple GPUs, your system is better equipped to handle these future demands without requiring significant upgrades.
GPU Workstations: Powering Professional Applications
Having a powerful GPU, or even multiple GPUs, can provide a significant advantage for professionals in fields like 3D rendering, data science, and video editing. Workstations equipped with multiple GPUs can handle larger datasets, render complex scenes faster, and streamline workflow. Here are some key benefits:
- Faster Rendering Times: Multiple GPUs speed up the process of calculating how light interacts with 3D models, resulting in quicker 2D image or animation production.
- Enhanced Data Processing: GPUs’ parallel processing capabilities accelerate complex algorithm computations in data science and machine learning. A multi-GPU workstation can handle larger datasets and perform calculations more efficiently.
- Smooth Video Editing: Multiple GPUs distribute the workload, improving the editing process when working with high-resolution videos or complex effects. This leads to a faster, more efficient workflow.
However, not all professional software takes full advantage of a GPU workstation. It’s crucial to check the software specifications and ensure that your chosen programs can effectively utilize multiple GPUs. Alternatively, you may consider a workstation with a single professional-grade GPU, such as the Nvidia Quadro or AMD Radeon Pro series. These GPUs offer features not found in consumer-grade cards, including larger VRAM, ECC memory, and optimized drivers for professional applications.
A Few More Multi-GPU Considerations
- Expensive Costs: High-end graphics cards can come with a hefty price tag, and purchasing multiple cards can quickly strain your budget. Additionally, setting up a multi-GPU configuration may necessitate other system upgrades like a more powerful power supply or a compatible motherboard, further increasing the overall expenses.
