NVIDIA GTX 1080

Sitting at the top of NVIDIA's mobile Pascal lineup, the GTX 1080 pairs 2560 cores with faster GDDR5X memory on the same 256-bit bus as the 1070, and a 150W power ceiling that puts it closer to a desktop card's performance than almost any laptop GPU before it.

This was the chip behind the first wave of genuinely desktop-replacement gaming laptops capable of 1440p at high settings, or 1080p comfortably past 100 fps in most titles. Expect a large, well-cooled chassis in any laptop built around it - this level of performance was never going to fit in anything thin.
