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 ...
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 ...
All other cards use GDDR6X video memory manufactured by Micron. RTX 4060 and RTX 4060 Ti have a limited 8 lane PCI Express 4.0 bus interface. All other cards support the full 16 lanes. There is a slower (on average 1% slower according to a single review [17] so far) variant of the RTX 4070 with 20Gbps GDDR6 VRAM introduced in August 2024. All ...
The Infinity Cache is made up of two sets of 64 MB cache that can run on its own clock rate independent from the GPU cores. The Infinity Cache has a peak internal transfer bandwidth of 1986.6 GB/s and results in less reliance being placed on the GPU's GDDR6 memory controllers. [ 8 ]
The 2022 release of Grand Theft Auto V for the ninth generation of video game consoles introduced several enhancements, incorporating features from later RAGE titles. Raytraced reflections, native 4K resolution on the PlayStation 5 and Xbox Series X, upscaled 4K on the Xbox Series S, as well as HDR support were added.
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.
On February 20, 2013, it was announced that the PlayStation 4 would use sixteen 4 Gb GDDR5 memory chips for a total of 8 GB of GDDR5 @ 176 Gbit/s (CK 1.375 GHz and WCK 2.75 GHz) as combined system and graphics RAM for use with its AMD-powered system on a chip comprising 8 Jaguar cores, 1152 GCN shader processors and AMD TrueAudio.

The 16-way associative L1 cache shared across a shader array is doubled in RDNA 3 to 256 KB. The L2 cache increased from 4 MB on RDNA 2 to 6 MB on RDNA 3. The L3 Infinity Cache has been lowered in capacity from 128 MB to 96 MB and latency has increased as it is physically present on the MCDs rather than being closer to the WGPs within the GCD ...
