We are already familiar with the possible layout for future AMD processors with Zen architecture , which means the proximity of two crystals. At least in the server segment, such an approach must justify itself. Beyond3D Forum participants, without claiming the title of clairvoyants suggest that NVIDIA can use double-crystal layout for flagship graphics solutions Pascal generation. In any case, the presence of silicon bridge needed to work with the HBM memory types, such integration greatly simplifies. In addition, the GPU Pascal this level (GP100) should support high-speed NVLink interface that hangs the exchange of information between the two crystals in tandem. We emphasize that both the crystal must coexist on the same substrate .
The authors believe the hypothesis that at the stated performance level monolithic GPU would have made too big and hot, and so are not very profitable for NVIDIA in the production and further exploitation. The separation of computing resources on the two chips would allow NVIDIA to save on costs, and reduce specific energy consumption. Related Products :
