Specifikationer
GeForce GTX 1070 bruger den samme Pascal GP104 processor som GTX 1080, men blot med 1920 aktive shader enheder i stedet for 2560, hvilket også betyder at antallet af tekstur enheder er 120 i stedet for 160. Med 64 ROPS så er antallet det samme og ligeledes er rammængden på 8GB. Dog GTX 1070 anvender almindelig GDDR5 ram hvor imod GTX 1080 bruger GDDR5X,. GDDR5X giver den dobbelte båndbredde ved samme frekvens, derfor kører nVidia GTX 1070s Vram på hele 2GHz for at kompensere på forskellen.
