Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer 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.
Video memory was shared with the first 128 KiB of RAM. The exact size of the video memory could be reconfigured by software to meet the needs of the current program. An early hybrid system was the Commodore Amiga which could run as a shared memory system, but would load executable code preferentially into non-shared "fast RAM" if it was available.
It has either 128 MB or 256 MB of dedicated video memory, however it also supports TurboCache, giving it up to 512 MB of video memory. It has DDR2 type memory and uses 64-bits memory interface. The card also has 550 MHz core clock speed and 263 MHz or 324 MHz memory clock speed (526 MHz or 648 MHz effective). [5]
Dual-ported video RAM (VRAM) is a dual-ported variant of dynamic RAM (DRAM), which was once commonly used to store the framebuffer in graphics adapters.. Dual-ported RAM allows the CPU to read and write data to memory as if it were a conventional DRAM chip, while adding a second port that reads out data.
The products in this series are integrated onto the motherboard, have limited graphics processing power, and use the computer's main memory for storage instead of a dedicated video memory. They were commonly found on netbooks , low-priced laptops and desktop computers , as well as business computers which do not need high levels of graphics ...
The majority of video playback on a computer is controlled by the GPU. Once again, a GPU can be either integrated or dedicated. Video Memory is built-in RAM on the graphics card, which provides it with its own memory, allowing it to run smoothly without taking resources intended for general use by the rest of the computer.
Though the GeForce 3 Ti200 did become the first DirectX 8.0 card to offer 128 MiB of video memory, instead of the common 64 MiB norm for high-end cards of the time, it turned out that the GeForce 3's limitations prevented it from taking full advantage of it, while the Radeon 8500 was able to more successfully exploit that potential.
The GeForce 6 series (codename NV40) is the sixth generation of Nvidia's GeForce line of graphics processing units.Launched on April 14, 2004, the GeForce 6 family introduced PureVideo post-processing for video, SLI technology, and Shader Model 3.0 support (compliant with Microsoft DirectX 9.0c specification and OpenGL 2.0).
