  2. Shared graphics memory - Wikipedia

    en.wikipedia.org/wiki/Shared_graphics_memory

    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 needs of the current program.

  3. Video random-access memory - Wikipedia

    en.wikipedia.org/wiki/Video_random-access_memory

    GDDR5X SDRAM on an NVIDIA GeForce GTX 1080 Ti graphics card. 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.

  4. GPU switching - Wikipedia

    en.wikipedia.org/wiki/GPU_switching

    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, it is still counted as a dedicated ...

  5. Shared memory - Wikipedia

    en.wikipedia.org/wiki/Shared_memory

    HSA defines a special case of memory sharing, where the MMU of the CPU and the IOMMU of the GPU have an identical pageable virtual address space.. In computer hardware, shared memory refers to a (typically large) block of random access memory (RAM) that can be accessed by several different central processing units (CPUs) in a multiprocessor computer system.

  6. Graphics processing unit - Wikipedia

    en.wikipedia.org/wiki/Graphics_processing_unit

    Hybrid graphics cards are somewhat more expensive than integrated graphics, but much less expensive than dedicated graphics cards. They share memory with the system and have a small dedicated memory cache, to make up for the high latency of the system RAM. Technologies within PCI Express make this possible.

  7. Intel Xe - Wikipedia

    en.wikipedia.org/wiki/Intel_Xe

    The Xe MAX is an entry-level GPU that was first released on November 1, 2020, in China and is similar in most aspects to the integrated GPU found in Tiger Lake processors, the only differences being a higher clock speed, slightly higher performance and dedicated memory and a dedicated TDP requirement.

  8. General-purpose computing on graphics processing units

    en.wikipedia.org/wiki/General-purpose_computing...

    Because the GPU has access to every draw operation, it can analyze data in these forms quickly, whereas a CPU must poll every pixel or data element much more slowly, as the speed of access between a CPU and its larger pool of random-access memory (or in an even worse case, a hard drive) is slower than GPUs and video cards, which typically ...

  9. Dual-ported video RAM - Wikipedia

    en.wikipedia.org/wiki/Dual-ported_video_RAM

    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.
