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.
