Resizable BAR Performance Revisited
AMD's Resizable BAR Revolutionizes Gaming Performance
AMD's Resizable BAR (Base Address Register) technology is making waves in the gaming industry, delivering significant performance boosts to titles that support it. In a recent test, AMD's Radeon RX 6800 XT saw an impressive 7% average improvement in framerates with Resizable BAR enabled, while NVIDIA's GeForce RTX 3080 saw a modest 1% improvement.
A Double-Digit FPS Boost
Resizable BAR allows the GPU to access the entire frame buffer of the system memory at once, rather than having to request data in smaller chunks. This reduces overhead and can result in double-digit FPS gains in certain games. For example, in the popular title Assassin's Creed Valhalla, both AMD and NVIDIA GPUs saw significant performance improvements with Resizable BAR enabled.
Compatibility and Availability
To take advantage of Resizable BAR, users must have a compatible motherboard, BIOS, and graphics card. AMD's Resizable BAR support is available on all Radeon RX 6000 series cards, while NVIDIA's support is limited to the GeForce RTX 30 series. It is important to note that not all games support Resizable BAR, and some games may require specific BIOS settings to be enabled.
Conclusion
Resizable BAR is a game-changing technology that can unlock significant performance gains for gamers. While AMD's GPUs have seen the most benefit from this feature so far, NVIDIA's cards also show promise. As more games and hardware support Resizable BAR, it is expected to become an essential feature for high-end gaming.
