What To Know
- The memory management unit of the GPU informs the memory controller of the motherboard that it wants expanded access to the main memory.
- The Resizable BAR technology allows the CPU to access the entire GPU memory at once, as opposed to only the limited chunk that was previously allowed.
- Resizable Bar allows a system to access all of the memory installed on a system using a single, unified address space.
AMD’s Smart Access Memory (SAM) technology, which was launched at the CES 2021 technology fair, now works not only on the Ryzen 5000 and Radeon RX 6000 series processors but also on processors and graphics cards released before.
AMD’s SAM, previously known as resizable BAR, is a feature that increases the efficiency between the CPU, GPU and system memory. The way it works is simple: The memory management unit of the GPU informs the memory controller of the motherboard that it wants expanded access to the main memory. The memory controller then ensures that all memory to be read and written by the graphics card is added as fast memory.
Does Amd Gpu Support Resizable Bar?
Yes, AMD GPU supports Resizable BAR. AMD’s RDNA 2 GPUs and Ryzen 5000 processors offer Resizable BAR support. The Resizable BAR technology allows the CPU to access the entire GPU memory at once, as opposed to only the limited chunk that was previously allowed. This can increase performance in some games by up to 15%, depending on the game and the specific hardware configuration.
Resizable BAR support was added as part of AMD’s Radeon Software Adrenalin 2020 version 20.11.3 driver, which was released in December 2020. If you have a supported AMD GPU and a compatible motherboard, you can enable Resizable BAR in the BIOS settings.
However, it should be noted that not all games will support Resizable BAR, and those that do may not see a significant performance increase. Additionally, some motherboards may not support Resizable BAR with older AMD processors or GPUs.

What Is Resizable Bar?
Resizable Bar is a feature that allows the CPU to control the speed and timing of memory access. This helps to ensure that data is always read or written to memory in the correct order, and that memory accesses are completed as quickly as possible.
The Resizable Bar was first introduced in the Intel Xeon Scalable processors. It is designed to increase the performance of memory-intensive workloads, such as data analytics and in-memory computing.
To use the Resizable Bar, you will need to make sure that your motherboard and CPU are compatible with the feature. You will also need to update your BIOS to support the Resizable Bar.
Once the Resizable Bar is enabled, it will automatically adjust the speed and timing of memory access as needed. This means that you will not have to make any changes to your software or hardware to take advantage of the feature.
Overall, the Resizable Bar is a powerful tool that can help you get the most out of your memory-intensive workloads. If you are running these types of workloads, you should consider enabling the Resizable Bar to improve your performance.
How Does Resizable Bar Work?
Resizable Bar, also known as Dynamic Memory Management, is a technology that was developed in response to memory management issues on modern Intel servers. Resizable Bar is a new feature that has been available on many Intel processors since 2017.
Resizable Bar allows a system to access all of the memory installed on a system using a single, unified address space. This means that all of the memory can be accessed by any processor in the system.
Resizable Bar comes with a number of benefits. It allows for a higher level of memory efficiency, as processors can access all of their memory at once rather than having to access memory in chunks. It also helps to reduce latency, as memory can be accessed more quickly and with less overhead.
Resizable Bar can be enabled or disabled in the BIOS. If you want to enable Resizable Bar on your system, you will need to make sure that your motherboard supports it. You will also need to make sure that your operating system supports Resizable Bar.
Resizable Bar is a technology that is designed to improve the performance of Intel servers. However, it can also be used on desktop systems. If you have a modern Intel processor and are interested in improving the performance of your system, you may want to consider enabling Resizable Bar.
What Are The Benefits Of Using Resizable Bar?
Resizable bars are a type of graphical user interface (GUI) component that allows users to adjust the size of bars in a graph or chart. They are often used in visualization tools, such as dashboards and data exploration applications.
One of the main benefits of using resizable bars is that they allow users to customize the display of data to suit their needs. For example, a user may want to focus on a particular aspect of a data set and adjust the size of the corresponding bars in order to emphasize this focus. Additionally, resizable bars can be used to compare different data sets or to visualize trends over time.
Another benefit of using resizable bars is that they can help to reduce clutter and make complex data easier to understand. By allowing users to adjust the size of bars, it is possible to present a large amount of data in a more compact and organized manner. This can make data exploration more efficient and allow users to more easily identify patterns and trends.
Overall, resizable bars are a flexible and powerful tool that can be used for a variety of data visualization and analysis tasks. They can help users better understand and manipulate data, enabling them to make informed decisions based on their findings.
Are There Any Drawbacks To Using Resizable Bar?
Resizable Bars are a feature of modern graphics processing units (GPUs) that allow the memory attached to a GPU to be expanded by “resizing” it. This means that the memory can be increased in size, without the need to replace the GPU.
However, as with all things, there are drawbacks to using Resizable Bars. One drawback is that Resizable Bars can be slow and inefficient. This is because the memory must be resized in chunks, which can take a long time. Additionally, resizing the memory can cause the GPU to crash.
Another drawback to using Resizable Bars is that they can cause compatibility issues. Some older GPUs do not support Resizable Bars, and using them can cause problems with games that are designed to run on those GPUs.
Overall, Resizable Bars can be a useful tool for expanding the memory of a GPU, but there are also drawbacks that come with using them. It is important to carefully consider the pros and cons of using Resizable Bars before making a decision.
Takeaways
In conclusion, AMD GPU supports resizable BAR technology, providing enhanced performance and flexibility for gaming, content creation, and other tasks. By enabling this feature, users can leverage the full capabilities of AMD GPUs and enjoy a smoother, more immersive computing experience. Whether you’re a casual gamer or a graphics professional, AMD GPU with resizable BAR support is a great addition to your setup.
