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.
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.
Increasing memory bandwidth, even while increasing memory latency, may improve the performance of a computer system with multiple processors and/or multiple execution threads. Higher bandwidth will also boost performance of integrated graphics processors that have no dedicated video memory but use regular RAM as VRAM.
A two-star review by Jarred Walton in Tom's Hardware criticised its price, especially considering that it was released 3 years after most of the 16 series, while only performing better than the GTX 1050. Walton wrote that "the only real contender for the GTX 1630 is AMD's recently launched Radeon RX 6400, but this new Nvidia card actually makes ...
A 16GB [1] DDR4 SO-DIMM module by Micron DDR4 memory is supplied in 288-pin dual in-line memory modules (DIMMs), similar in size to 240-pin DDR3 DIMMs. DDR4 RAM modules feature pins that are spaced more closely at 0.85 mm compared to the 1.0 mm spacing in DDR3, allowing for a higher pin density within the same standard DIMM length of 133.35 mm ...
On 9 January 2017, SK Hynix announced 8 and 16 GB LPDDR4X packages. [ 23 ] [ 24 ] JEDEC published the LPDDR4X standard on 8 March 2017. [ 25 ] Aside from the lower voltage, additional improvements include a single-channel die option for smaller applications, new MCP, PoP and IoT packages, and additional definition and timing improvements for ...
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.
By reducing the I/O activity caused by paging requests, virtual memory compression can produce overall performance improvements. The degree of performance improvement depends on a variety of factors, including the availability of any compression co-processors, spare bandwidth on the CPU, speed of the I/O channel, speed of the physical memory, and the compressibility of the physical memory ...
