Each GPC ships with a dedicated raster engine and 28 SMs. Don't let that confuse you, it is 128 shader units per SM. The Nvidia Titan X (GP102-400) has 28 x 128 shader processors makes a total of 3,584 shader processors.Įach SM has a cluster of 64 shader / stream / cuda processors doubled up.The GeForce GTX 1080 Ti (GP102-350) has 28 x 128 shader processors makes a total of 3,584 shader processors.The GeForce GTX 1080 (GP104-400) has 20 x 128 shader processors makes a total of 2,560 shader processors.The GeForce GTX 1070 (GP104-200) has 15 x 128 shader processors makes a total of 1,920 shader processors.The GeForce GTX 1060 (GP104-400) has 10 x 128 shader processors makes a total of 1,280 shader processors.Thus two out of two GPCs have been disabled. The NVIDIA GeForce GTX 1080 Ti however is not fully enabled. There are 28 active (SM) clusters for a fully enabled Pascal GP102 GPU. The GP102 PolyMorph Engine also includes a new Simultaneous Multi-Projection units. Each SM is paired with a PolyMorph Engine that handles vertex fetch, tessellation, viewport transformation, vertex attribute setup, and perspective correction. Pascal GPUs are composed of different configurations of Graphics Processing Clusters (GPCs), Streaming Multiprocessors (SMs), and memory controllers. Much like in the past designs you will see pre-modelled SMX clusters that hold what is 2圆4 shader processors per cluster. The GPU is based on DX12 compatible architecture called Pascal.
