Is vram video memory?
yes.
VRAM (Video RAM, video random access memory) is a form of video memory. As the DRAM (memory) used in video graphics cards and graphics cards, it is a dual-port random access memory. , allowing simultaneous access to RAMDAC and image processing.
The random access memory on the graphics card is a dual-port memory that allows it to be accessed by all hardware (including central processing units, display chips, etc.) at the same time. It is about 20% faster than EDO DRAM, but the price is relatively high, and it is suitable for high color depth and high resolution graphics equipment. Display chips using VRAM include S3, 968, S3 ViRGE/VX, etc.
Video memory can store the color of each pixel on the screen.
Main function
The main function is to output the video data of the graphics card to the digital-to-analog converter, effectively reducing the workload of the graphics display chip. It adopts dual data port design, one of which is a parallel data output port and the other is a serial data output port. Mostly used for high-end memory in advanced graphics cards.
Video Memory
The full name of video memory is display memory, also known as frame buffer, which is used to store rendering data that has been processed or is about to be read by the display chip. Like a computer's memory, video memory is the hardware used to store graphics data. The picture displayed on the monitor is composed of pixels, and each pixel uses 4 to 64-bit data to control its brightness and color. These points constitute a frame of graphics. In order to keep the picture smooth, the pixel data of multiple frames to be output and processed must be saved in the video memory to achieve a buffering effect, and then transferred to the display chip and central processing unit for deployment. Finally, the calculation results are converted into graphics and output to the monitor.

How to increase VRAM in Windows 11
May 05, 2023 pm 04:25 PM
Are you receiving warnings about your computer's graphics card memory when using graphics-intensive software or a new game? To prevent these issues and run resource-intensive games or applications smoothly, you need a graphics card and RAM that meet its specifications. Whether your computer is old or has graphics issues for no apparent reason, you can fix the problem by adjusting a few parameters in certain situations. The method we will cover in this article is to increase VRAM in Windows 11, which is one of the most effective ways to get the most out of your computer, especially your graphics card. But before we get into it, let's see what VRAM is and what it does. So, without further ado, let’s get started. Why increase video memory? What aspects of gaming and graphics software do we need to point out?
New AI algorithm unveiled: power reduced to 1/50 of conventional configuration, memory usage reduced to 1/10
Jun 27, 2024 pm 03:54 PM
According to news from this site on June 27, a research team from the University of California, Santa Cruz has developed a new method that can run a large language model with a scale of 1 billion parameters using only 13W of power (equivalent to the power of a modern LED light bulb). . For comparison, a data center-level GPU used for large language model tasks requires about 700W. Under the AI wave, the main research directions of many companies and institutions are application and reasoning, and indicators such as efficiency are rarely considered. To alleviate this situation, the researcher eliminated the intensive technique of matrix multiplication and proposed a "ternion" solution, which has only three values of negative one, zero, or positive one. The team also created custom hardware using a highly customized circuit called a field-programmable gate array (FPGA), allowing them to maximize the use of
What is the most critical factor in determining graphics card performance?
Jul 27, 2021 pm 02:31 PM
The most critical factor that determines the performance of a graphics card is "video memory". The function of video memory is to temporarily store the data calculated by the GPU core. Therefore, video memory plays a vital role in the performance of the graphics card. Other factors that determine graphics card performance: memory type, stream processor, memory width, bandwidth, frequency, etc.
How to check your graphics card on Windows 11
Apr 13, 2023 pm 01:34 PM
How to Check Your Graphics Card on Windows 11 Checking your graphics card on Windows 11 is simple as long as you know where to look. To check your graphics card using Task Manager: Open Task Manager by right-clicking Start and selecting Task Manager from the menu. When Task Manager starts, click the Performance tab. Click on your GPU from the list - if you have more than one, they will be labeled GPU 0 and GPU 1. You can find the name of your graphics card in the upper right corner of the information panel. In the GPU Task Manager panel section, you'll find additional data at the bottom such as the card's memory, driver version, driver data, DirectX version, and physical location. like

To reduce game capacity and video memory usage, AMD previews demonstration of AI texture compression technology next month
Jun 28, 2024 am 01:58 AM
According to news from this website on June 27, AMD has announced that it will attend the European Graphics Rendering Symposium to be held in London next month to demonstrate its new neural texture block compression technology, which can reduce the storage and video memory usage of games. Note from this site: High-resolution textures are the main reason for the growing size and VRAM usage of contemporary large-scale games. Currently, the installation capacity of AAA-level games such as "Call of Duty", "Baldur's Gate 3" and "Destiny 2" exceeds 100GB, and these high-resolution textures also occupy a large amount of video memory, resulting in lags and performance degradation, especially A graphics card with 8GB of video memory is already unable to handle the above-mentioned AAA games. NVIDIA proposed a neural network-based method last year - Neural Texture Compression (NeuralTextureCo.
