Many modern GPUs rely on VRAM. In contrast, a GPU that does not use VRAM, and relies instead on system RAM, is said to have a unified memory architecture, or shared graphics memory. System RAM and VRAM have been segregated due to the bandwidth requirements of GPUs, [2] [3] and to achieve lower latency, since VRAM is physically closer to the GPU ...
The PC1512 shipped with 512 KB of RAM; it could be upgraded to 640 KB of RAM with 16 pieces of 4164-120 Dynamic RAM chips (64KBx1 per chip) and setting a jumper. [14] Video output was compatible with the CGA standard, with an extension allowing all 16 colours to be used in the 640×200 graphics mode.
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.
Two VRAM SIMM slots provide the ability to upgrade to 1 MB of VRAM, which allows for 32,768 color (16-bit) resolutions. [2] Unlike the preceding Quadra 700 and Quadra 900/950, on-board video provided by the Quadra 800 is not capable of operating at 24-bit color regardless of how much VRAM is installed, as 24-bit support was removed as a cost ...
The Intel 8080 used by these computers was an 8-bit processor, with 16-bit address space, which allowed it access up to 64 KB of memory; .COM executables used with CP/M have a maximum size of 64 KB due to this, as do those used by DOS operating systems for 16-bit microprocessors.
The SVI-838, also known as X'press 16, is the last microcomputer produced by Spectravideo (at Hong Kong). Although it was a PC clone , it had the standard sound and video coprocessors of the MSX2 , making it a hybrid system. [ 1 ]
Storage: 256 or 512 GB SSD, or 500 GB/1 TB 5400 RPM + 8 GB hybrid SSHD; Optical drive: External BD/DVD Graphics : NVIDIA GeForce GTX 860M (2 GiB or 4 GiB GDDR5) Display : 15.6" LED-backlit LCD ( 3840 × 2160 , 1920 × 1080 , or 1920 × 1080 multitouch)
Graphics DDR SDRAM (GDDR SDRAM) is a type of synchronous dynamic random-access memory (SDRAM) specifically designed for applications requiring high bandwidth, [1] e.g. graphics processing units (GPUs).
