what vram refers to

vram refers to "Video Random Access Memory", which is a form of video memory. Its 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. .

VRAM (Video RAM, Video Random Access Memory) is a form of video memory.

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.

Features: Allows access by all hardware (including central processing unit, display chip, etc.) at the same time.

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.
