The world of PC gaming and graphics processing is constantly evolving, with new technologies and innovations emerging to take performance to the next level. One such innovation is Resizable BAR (Base Address Register), a feature that allows NVIDIA graphics cards to tap into the full potential of their processing power. But what exactly is Resizable BAR, and more importantly, which cards support this game-changing technology?
What is Resizable BAR?
Resizable BAR is a feature developed by NVIDIA that enables their graphics cards to access and process larger amounts of data more efficiently. In traditional graphics processing, the GPU is limited by the amount of data it can access at any given time, which can lead to bottlenecks and reduced performance. Resizable BAR, on the other hand, allows the GPU to dynamically adjust the amount of data it can access, effectively increasing its processing power and reducing latency.
This is achieved by allowing the GPU to resize its BAR (Base Address Register), which is a region of memory that determines how much data the GPU can access at once. With Resizable BAR, the GPU can resize its BAR to match the specific needs of the application or game, resulting in improved performance and reduced memory usage.
The Benefits of Resizable BAR
The benefits of Resizable BAR are numerous, and can be seen in various aspects of graphics processing. Some of the key advantages include:
Improved Performance: By allowing the GPU to access and process more data, Resizable BAR enables faster frame rates, higher resolutions, and overall improved performance in demanding games and applications.
Reduced Latency: With Resizable BAR, the GPU can reduce latency by minimizing the amount of data it needs to transfer between system memory and its own memory. This results in more responsive gameplay and reduced lag.
Increased Efficiency: By dynamically adjusting the amount of data it can access, the GPU can reduce memory usage and minimize power consumption, leading to increased efficiency and reduced heat generation.

What is Resizable BAR?
Resizable BAR (Base Address Register) is a technology that allows CPUs to access the entire VRAM of a graphics card at once, rather than being limited to a fixed-sized aperture. This allows for improved performance and efficiency in certain workloads, particularly those that involve data transfer between the CPU and GPU. By having access to the full range of VRAM, the CPU can transfer data more efficiently, reducing latency and increasing throughput.
In traditional systems, the CPU can only access a small portion of the VRAM at a time, which can lead to performance bottlenecks. With Resizable BAR, the CPU can access the entire VRAM, allowing for more efficient data transfer and improved overall system performance. This technology is particularly useful in applications that require heavy data transfer between the CPU and GPU, such as 3D modeling, video editing, and gaming.
What are the benefits of Resizable BAR?
The main benefit of Resizable BAR is improved performance in applications that rely heavily on data transfer between the CPU and GPU. By allowing the CPU to access the entire VRAM at once, Resizable BAR can reduce latency and increase throughput, leading to faster rendering times, higher frame rates, and improved overall system responsiveness. Additionally, Resizable BAR can also help to reduce power consumption, as the CPU and GPU can work more efficiently together.
In practical terms, Resizable BAR can have a significant impact on gaming performance, particularly in games that use complex graphics and physics. With Resizable BAR, gamers can expect to see higher frame rates, reduced lag, and improved overall gaming experience. Additionally, Resizable BAR can also benefit professionals who use graphics-intensive applications, such as 3D modeling, video editing, and scientific simulations.
What GPUs support Resizable BAR?
Resizable BAR is supported by a range of NVIDIA and AMD graphics cards, including high-end models such as the NVIDIA GeForce RTX 3080 and AMD Radeon RX 6800 XT. However, it’s worth noting that not all GPUs support Resizable BAR, and even among those that do, some may require specific system configurations or driver updates to enable the feature.
To take advantage of Resizable BAR, you’ll need a compatible GPU, as well as a system that meets the necessary requirements, such as a compatible CPU and motherboard. It’s also important to ensure that your system is running the latest drivers and firmware, as Resizable BAR may not be enabled by default.
Do I need a specific CPU or motherboard to use Resizable BAR?
While Resizable BAR is a GPU technology, it does require specific system configurations to function properly. In particular, you’ll need a CPU and motherboard that support PCIe 4.0, as well as a compatible chipset. For NVIDIA GPUs, you’ll need a motherboard with an Intel Z490 or AMD X570 chipset, while for AMD GPUs, you’ll need a motherboard with an AMD X570 or B550 chipset.
Additionally, you’ll also need to ensure that your system is running the latest BIOS and UEFI firmware, as these updates often include support for Resizable BAR. It’s also important to note that even with a compatible system, Resizable BAR may not be enabled by default, so you may need to manually enable it in your system settings.
How do I enable Resizable BAR on my system?
Enabling Resizable BAR on your system will vary depending on your GPU and system configuration. For NVIDIA GPUs, you’ll need to enable the feature through the NVIDIA Control Panel, while for AMD GPUs, you’ll need to enable it through the AMD Vantage software. In addition, you may also need to enable Resizable BAR in your system BIOS or UEFI settings.
It’s also important to note that Resizable BAR may not be enabled by default, even on systems that support it. Therefore, you’ll need to manually enable it in order to take advantage of the performance benefits it provides. Additionally, you may need to update your drivers and firmware to the latest versions in order to enable Resizable BAR.
What are the limitations of Resizable BAR?
While Resizable BAR offers a number of benefits, it’s not without its limitations. One of the main limitations is that it requires specific system configurations, including a compatible GPU, CPU, and motherboard. Additionally, Resizable BAR may not be compatible with all systems or applications, and may require manual configuration to enable.
Another limitation of Resizable BAR is that it may not provide significant performance benefits in all workloads. In particular, applications that don’t rely heavily on data transfer between the CPU and GPU may not see significant improvements with Resizable BAR. Additionally, Resizable BAR may also increase power consumption in some systems, which could be a concern for mobile devices or systems with limited power budgets.
Is Resizable BAR worth it?
For systems that support Resizable BAR and can take advantage of its benefits, it’s definitely worth enabling. The performance improvements provided by Resizable BAR can be significant, particularly in applications that rely heavily on data transfer between the CPU and GPU. Additionally, Resizable BAR can also help to improve overall system responsiveness and reduce latency, making it a worthwhile feature for anyone looking to squeeze the most performance out of their system.
That being said, Resizable BAR may not be worth it for everyone. If your system doesn’t support Resizable BAR, or if you don’t use applications that can take advantage of its benefits, then it may not be worth the effort to enable it. Additionally, if you’re concerned about power consumption or have limited power budgets, then Resizable BAR may not be the best option for you. Ultimately, whether or not Resizable BAR is worth it will depend on your specific needs and system configuration.
