The NVIDIA GeForce RTX 2080 Super is a powerful graphics card that has been a favorite among gamers and graphics enthusiasts since its release. With its enhanced performance and features like ray tracing, artificial intelligence-enhanced graphics, and variable rate shading, it has set a new standard for high-end graphics cards. One feature that has garnered significant attention in recent times is the Resizable BAR (Base Address Register), which promises to enhance performance in certain applications by allowing the CPU to access the GPU’s memory more efficiently. In this article, we will delve into the details of the 2080 Super and explore whether it supports Resizable BAR.
Introduction to Resizable BAR
Resizable BAR is a feature that allows the CPU to access the GPU’s memory (VRAM) more efficiently by adjusting the size of the BAR. Traditionally, the BAR is fixed, which can lead to inefficiencies in data transfer between the CPU and GPU. By making the BAR resizable, the CPU can access larger chunks of VRAM, reducing the number of transactions required and thereby increasing performance. This feature is particularly beneficial in applications that rely heavily on CPU-GPU data transfer, such as 3D modeling, video editing, and gaming.
How Resizable BAR Works
The Resizable BAR feature works by allowing the CPU to adjust the size of the BAR based on the requirements of the application. When an application requires a large amount of data to be transferred between the CPU and GPU, the BAR can be resized to accommodate the larger data transfer. This reduces the number of transactions required, resulting in improved performance. The Resizable BAR feature is supported by the PCIe (Peripheral Component Interconnect Express) interface, which is the standard interface used for connecting graphics cards to the motherboard.
