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.
The Radeon Pro W7900 and W7800 support the 80Gbps UHBR20 standard. DisplayPort 2.1 can support 4K at 480 Hz and 8K at 165 Hz with Display Stream Compression (DSC). The previous DisplayPort 1.4 standard with DSC was limited to 4K at 240 Hz and 8K at 60 Hz.

Dual-ported video RAM (VRAM) is a dual-ported RAM variant of dynamic RAM (DRAM), which was once commonly used to store the Framebuffer in Graphics card, . 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 best graphics cards are the beating heart of any gaming PC, and everything else comes second. Without a powerful GPU pushing pixels, even the fastest CPU won't manage much.
Both Wide I/O 2 and HBM utilize a very wide parallel memory interface—up to 512 bits for Wide I/O 2 compared to 64 bits for DDR4—although they operate at lower frequencies than DDR4. Wide I/O 2 is designed for high-performance, compact devices, often integrated into processors or system on a chip (SoC) packages.
A notable exception was the IBM PC. Graphics display was facilitated by the use of an expansion card with its own memory plugged into an ISA slot. The first IBM PC to use the SMA was the IBM PCjr, released in 1984. 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 Nvidia Geforce 500 series graphics cards are significantly modified versions of the GeForce 400 series graphics cards, in terms of performance and power management.Like the Nvidia GeForce 400 series graphics cards, the Nvidia GeForce 500 series supports Direct3D 12.0 (feature level 11.0), OpenGL 4.6, and OpenCL 1.1.
