Incredible Energy Efficiency
All GeForce GPUs are made to deliver performance leadership in their respective segment. But PC
gamers also expect efficiency—not noisy fans, excessive heat, and over-taxed power supplies. The
desktop PC gaming market is seeing increasing popularity of smaller and thinner form factors, and the
laptop PC gaming market has grown explosively in the past few years.
The Maxwell architecture was designed to provide an extraordinary leap in power efficiency and deliver
unrivaled performance while simultaneously reducing power consumption from the previous
generation. With a combination of advances originally developed for Tegra K1, new architectural
approaches seen first in the GeForce GTX 750 Ti, and further refinement for GM204, Maxwell now
delivers 2x the performance per watt compared to Kepler products.
