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.
In computing, hardware overlay, a type of video overlay, provides a method of rendering an image to a display screen with a dedicated memory buffer inside computer video hardware. The technique aims to improve the display of a fast-moving video image — such as a computer game, a DVD, or the signal from a TV card.
Also known as: discrete graphics cards. Unlike integrated graphics, dedicated graphics cards have much more processing units and have its own RAM with much higher memory bandwidth. In some cases, a dedicated graphics chip can be integrated onto the motherboards, B150-GP104 for example. Regardless of the fact that the graphics chip is integrated ...
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. The term "Video" here is an informal designation and is not intended in a narrow sense.
The term "dedicated" refers to the fact that graphics cards have RAM that is dedicated to the card's use, not to the fact that most dedicated GPUs are removable. Dedicated GPUs for portable computers are most commonly interfaced through a non-standard and often proprietary slot due to size and weight constraints.
The M3's Unified Memory Architecture (UMA) is similar to the M2 generation; M3 SoCs use 6,400 MT/s LPDDR5 SDRAM. As with prior M series SoCs, this serves as both RAM and video RAM. The M3 has 8 memory controllers, the M3 Pro has 12 and the M3 Max has 32. Each controller is 16-bits wide and is capable of accessing up to 4 GiB of memory. [14]
Macintosh Performa 638CD: The 637CD without the monitor, but with a TV/video-in card instead - The Performa 638 CD/V shipped with TV tuner card and 15" Multiple Scan Display. [14] Introduced November 3, 1994: Macintosh LC 630: Same as the Performa 630, [15] sold in the K-12 education market. US$1,299 with 4 MB RAM; $1,949 with 8 MB RAM and a 2 ...
The new MacBook Pro computers had two video cards that the user could switch between: the Nvidia GeForce 9600M GT with either 256 or 512 MB [36] of dedicated memory and a GeForce 9400M with 256 MB of shared system memory. [34] Although the FireWire 400 port was removed, the FireWire 800 port remained.
