Improving upon its popular predecessor, the GTX 980, this upgraded version blows it out of the water in both performance and size. Thanks to its innovative Pascal architecture—which has been in the making since 2012—this GPU delivers clocking speeds up to 1708 MHz (and plenty more with overclocking). It packs 7.2 billion transistors into a smaller fabrication process, which makes for a more powerful, more compact, and more energy efficient GPU.
