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.
Graphics Double Data Rate 5 Synchronous Dynamic Random-Access Memory (GDDR5 SDRAM) is a type of synchronous graphics random-access memory (SGRAM) with a high bandwidth ("double data rate") interface designed for use in graphics cards, game consoles, and high-performance computing. [1]
This list contains general information about graphics processing units (GPUs) and video cards from Nvidia, based on official specifications.In addition some Nvidia motherboards come with integrated onboard GPUs.
All other cards use GDDR6X video memory manufactured by Micron. RTX 4060 and RTX 4060 Ti have a limited 8 lane PCI Express 4.0 bus interface. All other cards support the full 16 lanes. There is a slower (on average 1% slower according to a single review [17] so far) variant of the RTX 4070 with 20Gbps GDDR6 VRAM introduced in August 2024. All ...
Also residing within the main CPU, enables full screen, high quality FMV playback and is responsible for decompressing images and video into VRAM. [5] Operating performance: 80 MIPS [11] Documented device mode is to read three RLE-encoded 16×16 macroblocks, run IDCT and assemble a single 16×16 RGB macroblock.
The reduced bus width is compensated by a doubled minimum burst length of 16, which preserves the minimum access size of 64 bytes, which matches the cache line size used by modern x86 microprocessors. [17] DDR5 also decreased the refresh rate to 32 ms from 64 ms when operating above 85°C. It also provides two refresh commands: REFab and REFsb.
A modern consumer graphics card: A Radeon RX 6900 XT from AMD. A graphics card (also called a video card, display card, graphics accelerator, graphics adapter, VGA card/VGA, video adapter, display adapter, or colloquially GPU) is a computer expansion card that generates a feed of graphics output to a display device such as a monitor.
Sun TGX Framebuffer. A framebuffer (frame buffer, or sometimes framestore) is a portion of random-access memory (RAM) [1] containing a bitmap that drives a video display. It is a memory buffer containing data representing all the pixels in a complete video frame. [2]
