Battery Boost balances performance and power consumption by assessing characteristics of each game, and the adjustments kick in once a game starts.Īs on the PS4, laptops with the GPUs will be able to record gameplay through a feature called ShadowPlay. The power efficiency comes partly from a new feature called Battery Boost, which can adjust GPU operations depending on a game's requirements. Nvidia measured 2 hours and 11 minutes of gameplay time for Borderlands 2 at 30 frames per second and a 1080p screen resolution on a laptop with an 860M, almost twice the battery mileage compared to predecessors, Sanghani said. The 860M, 870M and 880M can render graphics at a 4K resolution of 3840 x 2160 pixels, but laptops with 4K displays are not available yet. Games like Assassin's Creed IV, Black Flag and Arkham Origins can be played at a 1080p resolution with the 850M and 860M, and at more frame rates per second with 870M and 880M, Nvidia said. Hopefully the massive performance-per-watt increases the first Maxwell desktop cards have shown will be as good on the mobile side,' Reeves said. 'We'll be revving our laptop lines from 700 to 800 series though, and don't expect any significant price changes. CEO Kelt Reeves hasn't tested the GPUs yet, but has high expectations. Gaming PC maker Falcon Northwest will be updating its laptops to include the new GTX 800M series chips. Prices for the laptops were not immediately available. The GTX 870M will be in Razer's Blade laptop, while Lenovo's Y50 and Gigabyte's P34 will have the Maxwell-based 860M GPU.

The fastest GTX 880M will go into MSI's GT70, Dell's Alienware 17 and Asustek's G750, which have 17.3-inch screens.

PC makers will put the new GPUs in laptops, though it is not clear when the systems will ship. The GTX mobile GPUs are embedded on a motherboard and will let laptop users play some of the latest gaming titles, which are heavy on graphics and special effects, Sanghani said. Most laptops today are sold with integrated graphics processors, which are good enough for casual gaming. The company has already shipped desktop GPUs based on Maxwell, which will also be used in Linux-based gaming desktops called Steam Machines due to ship later this year.
