Video random-access memory (VRAM) is dedicatedcomputer memory used to store thepixels and other graphics data as aframebuffer to be rendered on a computer monitor.^[1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.

Independent system RAM and video RAM

Unified memory

Many modern GPUs rely on VRAM. In contrast, a GPU that doesnot use VRAM, and relies instead on system RAM, is said to have aunified memory architecture, orshared graphics memory.

System RAM and VRAM have been segregated due to the bandwidth requirements of GPUs,^[2][3] and to achieve lower latency, since VRAM is physically closer to the GPU die.^[4]

Modern VRAM is typically found in aBGA package^[5] soldered onto a graphics card.^[6] The VRAM is cooled along with the GPU by the GPU heatsink.^[7]
