Gamers often wonder why a graphics card has a certain amount of VRAM.Ĭurrent-generation GDDR6X and GDDR6 memory is supplied in densities of 8Gb (1GB of data) and 16Gb (2GB of data) per chip. The Amount of VRAM Is Dependent On GPU Architecture When designing our GeForce RTX 40 Series GPUs, we found a singular, large L2 cache to be faster and more efficient than other alternatives, such as those featuring a small L2 cache, and a large, slower to access 元 cache. This is followed by a fast, larger, shared Level 2 (L2) cache that can be accessed quickly with minimal latency.Īccessing each cache level incurs a latency hit, with the tradeoff being greater capacity. GeForce GPUs feature a Level 1 (L1) cache (the closest and fastest cache) in each Streaming Multiprocessor (SM), up to twelve of which can be found in each GeForce RTX 40 Series Graphics Processing Cluster (GPC). If the GPU can recall the data from the caches, rather than requesting it from the VRAM (further away) or system RAM (even further away), the data will be accessed and processed faster, increasing performance and gameplay fluidity, and reducing power consumption. GPUs include high-speed memory caches that are close to the GPU’s processing cores, which store data that is likely to be needed.
