According to earlier reports, the GP106 powered graphics card will arrive in the fall. The size appears to be around 200mm² and if the GPU has two Global Processing Clusters then it will be up to 1280 CUDA cores.
The GTX 1060 will double the bus width available to its predecessor for a total of 256-bits worth of bus width. The GTX 960 only had a 128-bit bus width.
The GP106 will use high density GDDR5 (256MX32 configuration). With the bus width is 256-bits, we can expect either 4GB or 8GB of vRAM.
But the entry only mentions the GP106 GPU, so the information contained in the manifest can pertain to either the GTX 1060 or the GTX 1060 Ti.
