Nvidia launches Geforce GTX 800M series and Maxwell for laptops

After the launch of the Geforce GTX 750 and GTX 750 Ti with Maxwell, it was only a matter of time before the architecture would find its way into laptops. Nvidia is now launching the new Geforce 800M series, which houses the Maxwell and the previously known graphics circuit GM107 in the middle performance class.

The Geforce GTX 850M consists of full-scale GM107, which means 640 CUDA cores and a 128-bit memory bus. These include clock speeds of 936 MHz and up for the graphics circuit and 5,000 MHz for the GDDR5 memory. The step up in the performance ladder is the GTX 860M, which either means a higher clocked GM107 or a stripped-down variant of the faithful servant GK104 with the architecture Kepler.

Furthermore, the GTX 870M with 1,344 CUDA cores and a 192-bit memory bus with up to 3 GB of GDDR5 memory in 5,000 MHz is visible. The series is topped by the GTX 880M with full-scale GK104, a graphics circuit that thus constitutes Nvidia’s flagship for laptops three generations in a row.

In addition to high-performance solutions in the Geforce GTX series, the Geforce 840M and 830M are introduced, which promise higher performance and energy efficiency than Intel’s integrated solutions. The newcomers are based on the GM108 graphics circuit with the Maxwell architecture, but apart from a 64-bit memory bus and up to 2 GB DDR3, no other specifications appear.

Nvidia also introduces a new technology with the Geforce GTX 800M series: Battery Boost. By locking the frame rate to a fixed value (30 fps is the standard level) and controlling the clock frequencies throughout the system, it should be possible to get up to twice as long operating time while playing. The finesse is adjustable for those who want to play at more than 30 fps at the expense of battery life.

New is also that Geforce Shadowplay is coming to laptops. It is a technology that, with the help of built-in video encoders in the graphics circuits, records the game session directly to H.264. Finally, Gamestream is also added, which enables streaming of games via wireless network from a computer with Nvidia graphics card to the Nvidia Shield portable game console.

The first laptops with the Nvidia Geforce GTX 800M series are expected to find out soon and more models are expected in the summer months.
