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 ...
25 MHz 68040, 24 MB RAM (including 8 MB on board), 1 MB VRAM, 500 MB HDD, Ethernet; Introduced October 21, 1993: Macintosh Quadra 650: [5] 33 MHz 68040. As the Macintosh IIvx shares the same desktop form factor, it can be upgraded to the Centris/Quadra 650 by swapping the logic board. [6]
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.
Random-access memory (RAM; / r æ m /) is a form of electronic computer memory that can be read and changed in any order, typically used to store working data and machine code.
A new version of the Y500 with upgraded features was released in June along with the Lenovo Y410p. The upgraded version has following features compare to older version Display: 1366 × 768 TN (1920 × 1080 was present in older version) Graphics: Intel HD 4600 + NVIDIA GeForce GT 750M (NVIDIA GeForce GT 650M was in older version)
A Color Classic with the Mystic upgrade can go up to Mac OS 8.1 (Mac OS 8.6 and newer require PowerPC processors). With the Takky mod, the case and connector need to be modded, but doing so will allow the use of a PowerPC 601, 603, or 604 equipped motherboard.
The new chip can work at up to 7 GHz effective clock-speed and will be used in graphics cards and other high bandwidth memory applications. [15] "4 Gb" (4 × 1024 3 bit) GDDR5 components became available in the third quarter of 2013. Initially released by Hynix, Micron Technology quickly followed up with their implementation releasing in 2014.
Graphics Double Data Rate 7 Synchronous Dynamic Random-Access Memory (GDDR7 SDRAM) is a type of synchronous graphics random-access memory (SGRAM) specified by the JEDEC Semiconductor Memory Standard, with a high bandwidth, "double data rate" interface, designed for use in graphics cards, game consoles, and high-performance computing.
