GDDR4 SDRAM, an abbreviation for Graphics Double Data Rate 4 Synchronous Dynamic Random-Access Memory, is a type of graphics card memory (SGRAM) specified by the JEDEC Semiconductor Memory Standard. [ 1 ] [ 2 ] It is a rival medium to Rambus's XDR DRAM .
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).
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.
Graphics Double Data Rate 5 Synchronous Dynamic Random-Access Memory (GDDR5 SDRAM) is a type of synchronous graphics random-access memory (SGRAM) with a high bandwidth ("double data rate") interface designed for use in graphics cards, game consoles, and high-performance computing. [1] It is a type of GDDR SDRAM (graphics DDR SDRAM).
The separate JEDEC standard Low Power Double Data Rate 5 (LPDDR5), intended for laptops and smartphones, was released in February 2019. [15] Compared to DDR4, DDR5 further reduces memory voltage to 1.1 V, thus reducing power consumption. DDR5 modules incorporate on-board voltage regulators in order to reach higher speeds.
In part, this is because changes required to other components would affect all other parts of computer systems, which would need to be updated to work with DDR4. [37] 2014: In April, Hynix announced that it had developed the world's first highest-density 128 GB module based on 8 Gbit DDR4 using 20 nm technology. The module works at 2133 MHz ...
