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.
HyperMemory was a brand for ATI's method of using the motherboard's main system RAM as part of or all of the video card's video memory on their line of Radeon video cards and motherboard chipsets. It relies on new fast data transfer mechanisms within PCI Express .

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. An early hybrid system was the Commodore Amiga which could run as a shared memory system, but would load executable code preferentially into non-shared "fast RAM" if it was available.
A GART is used as a means of data exchange between the main memory and video memory through which buffers (i.e. paging/swapping) of textures, polygon meshes and other data are loaded, but can also be used to expand the amount of video memory available for systems with only integrated or shared graphics (i.e. no discrete or inbuilt graphics ...
The Radeon HD 7000 series, codenamed "Southern Islands", is a family of GPUs developed by AMD, [9] and manufactured on TSMC's 28 nm process. [10]The primary competitor of Southern Islands was Nvidia's GeForce 600 series (also manufactured at TSMC), which shipped during Q1 2012, largely due to the immaturity of the 28 nm process.
ROCm [3] is an Advanced Micro Devices (AMD) software stack for graphics processing unit (GPU) programming. ROCm spans several domains: general-purpose computing on graphics processing units (GPGPU), high performance computing (HPC), heterogeneous computing.
At Hot Chips 2016, Samsung announced GDDR6 as the successor of GDDR5X. [5] [6] Samsung later announced that the first products would be 16 Gbit/s, 1.35 V chips.[7] [8] In January 2018, Samsung began mass production of 16 Gb (2 GB) GDDR6 chips, fabricated on a 10 nm class process and with a data rate of up to 18 Gbit/s per pin.
