Nvidia’s new GPU series GeForce 800M is designed primarily for notebook players who want to enjoy the pure Gaming Experience. The family released seven GPU models, four of which Battery Boost Technology dominates: Geforce GTX 850M, 860M, 870M and 880M, the top model. The entry-level models 820M, 830M and 840M without a preceding GTX not dominate the energy-saving function and are designed for budget notebooks.

The battery Boost is basically a new way in which Nvidia is trying to limit the power consumption in the Gaming Mode when the battery is running. The user chooses a frame rate from that which he wants to play and the driver then limits the computation of images in order to conserve battery power. With appropriate reserves Nvidia expects at best a doubling of battery life.
For the battery Boost, the requirements of the game should not be too high. A strategy game can be, for example, certainly with less than 20 frames per second play. When 3D shooter it should be more like 30 fps, the default setting of the Nvidia driver for the battery. Nvidia’s Optimus technology for switching between graphics cores support the new models also.
Nvidia GeForce 800M Series Maxwell and Kepler
Nvidia leaving manufacturers of notebook hardware, some freedoms. The GPU Geforce GTX 850M, there are two models GDDR3 and GDDR5 memory. All higher models only support GDDR5. In the 860M, the number of Cuda units can at the level of the GTX 850M are (640 units) or with 1,156 units close to the GTX 870M (1,344 units). The reason is that there is the model GTX 860M with two different cores: Maxwell and Kepler.
Maxwell is also found in the model GTX 850M, while the larger models are all based on the Kepler architecture.
