•Video RAM is just like a normal RAM but dedicated memory on a computer’s graphics card or graphics processing unit (GPU) that stores and manages data related to graphics and video processing.
•Here video RAM’s process the picture so that the monitor can show us the picture.
•All types of VRAMs are special arrangements for dynamic RAM.
•The video RAM is a buffer between the computer and the monitor.
•It is also called a frame buffer.
•When images are sent to display on the screen by the system, they are read by the processor onto the dedicated video RAM or integrated video RAM. Then the video is processed into the RAM and appears on the monitor.
•Previous high-performance Video RAM types were a double-ported.
•While the CPU is taking a new picture to VRAM, the screen reads from VRAM to modify its current display data.
•The double-port design was the main difference between computer RAM and video RAM in the 1980s and 1990s.
Multibank Dynamic RAM
•It is a high-performance RAM, it separates memory into multiple 32-kilobyte sections or banks.
•It can be independently accessed.
•Traditional VRAM is monolithic with access to the entire frame buffer at one time.
•But in contiguous memory banks a single segment of memory is assigned to execute the process
•Multibank Dynamic RAM is also cheaper since cards can be produced with only the correct amount of space for a given resolution bandwidth, rather than multiple megabytes.
Synchronous Graphics RAM
•It is a relatively low-cost, clock-synchronized DRAM video memory.
•SGRAM is singular-port memory, but this can function like dual-port memory by constructing new memory pages simultaneously, rather than just one.
VRAM usage
•Modern graphics cards use an SGRAM(Synchronous Graphics Random Access Memory) variant called GDDR5(Double Data Rate 5 Synchronous Dynamic Random-Access Memory).
•GDDR5 is the RAM double data rate. The DDR4 is used in today’s electronics as machine RAM.
•The only key difference between VRAM and device RAM is the speed and the potential to imitate dual-port functionality.
•VRAM is needed in case of complex textures of images or render three-dimensional structures.
•Video games or 3D graphic design software are the most popular example of these applications.
•VRAM plays an important role in efficiency with gaming, such as loading times and image quality.
•Rendering a massive AAA game at 1920*1080 resolution is different from rendering a game at 4K UHD quality.
•It requires extra graphics memory (like 6GB, 8GB, 12GB).
•Extra Video RAM is needed to render an image of high quality.
•It helps the user to have the proper textures and images.
