At the 2016 GPU Technology Conference, Nvidia finally unveiled the Pascal GPU architecture. Perhaps the most interesting aspect of the GPU aren’t the capabilities the Pascal architecture brings, but rather the first non-Intel driven high-end bandwidth interface since AMD launched HyperTransport in 2001. NVLink standard launched in 2014, when IBM announced its tie up with Nvidia to bring the high-speed interconnect to the market. The goal of NVLink is to remove its future GPU architectures from the dependencies of PCI Express, and achieve maximum bandwidth. If NVLink was replaced with 100% PCIe lanes, the design simply would not be as efficient in terms of lines needed, and would
