The Benefits of Resizable BAR for AMD CPUs and Nvidia GPUs

The resizable BAR, also known as Smart Access Memory, is a feature that allows the CPU to access the entire VRAM of the GPU at once, providing a potential boost in gaming performance. This technology has gained significant attention among gamers and PC enthusiasts, as it promises to unlock the full potential of the AMD CPU and Nvidia GPU combination. In this article, we will delve into the unique aspects of the resizable BAR technology, exploring its benefits and impact on gaming performance.

What is Resizable BAR and How Does it Work?

Resizable BAR is a technology that improves the communication between the CPU and GPU by allowing the CPU to access the GPU's entire VRAM in a single pass. Traditionally, the CPU could only access small portions of the VRAM at a time, which limited the efficiency and speed of data transfer. With the implementation of resizable BAR, the CPU can address the full VRAM, leading to faster and more efficient data transfers.

When the CPU needs to access data stored in the VRAM, it sends a request to the GPU. In the traditional method, the GPU provides the requested data to the CPU in small chunks, causing multiple data transfers and increasing latency. However, with resizable BAR enabled, the GPU grants the CPU access to the entire VRAM, allowing for a single data transfer. This reduces latency and improves overall performance by reducing data transfer overhead.

To take advantage of the resizable BAR technology, both the CPU and GPU must support it. Currently, the resizable BAR technology is available in select AMD CPUs, starting from the Ryzen 5000 series, and Nvidia GPUs, starting from the RTX 3000 series. Additionally, the motherboard's BIOS must support resizable BAR and have it enabled as well.

Boost in Gaming Performance

One of the key benefits of resizable BAR is the potential boost in gaming performance. By enabling resizable BAR, the CPU can directly access the entire VRAM of the GPU, which reduces the overhead and improves the speed of data transfer. This can result in faster loading times, smoother gameplay, and increased frame rates.

When the CPU can access the VRAM more efficiently, it can retrieve and process the necessary data faster, allowing for quicker rendering of game assets and improved overall performance. This is particularly noticeable in games that rely heavily on data streaming, where large amounts of data need to be loaded and processed in real-time.

The impact of resizable BAR on gaming performance can vary depending on the specific game and system configuration. In some cases, the difference may be marginal, while in others, it can provide a noticeable improvement. It is recommended to consult the game's compatibility list and perform benchmark tests to determine the impact of resizable BAR on a particular game.

Compatibility and Requirements

To benefit from resizable BAR, it is important to ensure compatibility and meet the necessary requirements. As mentioned earlier, both the CPU and GPU must support resizable BAR. For AMD CPUs, this includes the Ryzen 5000 series or newer, while for Nvidia GPUs, it includes the RTX 3000 series or newer.

In addition to CPU and GPU compatibility, the motherboard's BIOS must also support resizable BAR and have it enabled. It is recommended to check the motherboard manufacturer's website for BIOS updates that enable resizable BAR. Enabling resizable BAR can usually be done through the BIOS settings, where an option to enable or disable it is provided.

It is worth noting that not all games fully utilize the benefits of resizable BAR, and some may not show any noticeable improvement in performance. However, with the increasing support from game developers and hardware manufacturers, more games are expected to maximize the advantages of resizable BAR in the future.

Performance Benchmarks and Real-World Results

Various performance benchmark tests have been conducted to evaluate the impact of resizable BAR on gaming performance. Results have shown that enabling resizable BAR can lead to performance improvements in certain games, especially at higher resolutions and when using demanding graphics settings.

For example, in games like Cyberpunk 2077, Assassin's Creed Valhalla, and Watch Dogs: Legion, enabling resizable BAR has resulted in noticeable performance gains, including higher average frame rates and smoother gameplay. However, it is important to note that the performance impact may vary depending on factors such as the specific system configuration and the optimization of the game for resizable BAR.

To evaluate the real-world impact on gaming performance, it is recommended to perform benchmark tests before and after enabling resizable BAR. This can provide insights into the actual performance gains and determine whether enabling resizable BAR is beneficial for a specific system and game combination.

Enabling Resizable BAR

Enabling resizable BAR involves ensuring compatibility and making the necessary settings in the system BIOS. The steps to enable resizable BAR may vary depending on the motherboard manufacturer and BIOS version. However, the general process involves the following:

• Update the motherboard's BIOS to the latest version that supports resizable BAR.
• Access the BIOS settings by pressing the designated key during system boot (usually Del or F2).
• Navigate to the "Advanced" or "Advanced settings" section of the BIOS.
• Look for an option related to resizable BAR, such as "Resizable BAR" or "Smart Access Memory." Enable this option.

After enabling resizable BAR in the BIOS, save the settings and exit. The system will restart, and resizable BAR will be enabled, allowing the CPU to access the GPU's VRAM more efficiently.

Improved Gaming Experience with Resizable BAR

Resizable BAR technology has the potential to enhance the gaming experience for PC enthusiasts. By enabling the CPU to access the entire VRAM of the GPU at once, resizable BAR reduces data transfer latency, resulting in faster and more efficient performance. With supported AMD CPUs and Nvidia GPUs, gamers can unlock the benefits of resizable BAR and maximize their gaming potential.
