NV Link

NVLink can be scalable memory and performance in respect of VRAM, Bandwidth, CUDA cores, and so on. Typically, VRAM for each graphics card does not stack in multi-GPU processing. When a project requires a large amount of VRAM, NVLink is needed. This NVLink feature enables you to pool together resources like the VRAM. For instance, there are 48GB of VRAM available when using 2x RTX 3090s (each 24GB) due to the memory pooling capabilities of NVLink.
