Nvidia GeForce GTX 1070 is the second Pascal architecture card that uses the GP104 core. But as you would it expect from a model below a high-end graphic card, it does have some sections disabled. Another factor to consider is that the GeForce GTX 1070 uses the GDDR5 memory, unlike GDDR5x on the GTX 1080. Apart from the model number, you cannot differentiate between two cards visually.
