Nvidia has refreshed its mobile graphics processor line and claimed that its chips that deliver more horsepower while consuming less electrical power.
The GeForce GTX 880M and the GeForce GTX 870Mare based on Nvidia's 28nm Kepler microarchitecture. Kepler also forms the basis of Nvidia's most powerful desktop GPUs, including the GeForce GTX Titan Black. The GeForce GTX 850M is based on Nvidia's newer 28nm microarchitecture, codenamed Maxwell.
The GeForce GTX 860M is available in either a Kepler or Maxwell flavours, depending on what the OEM needs. Bboth GPUs will deliver similar performance but they'll have different power consumption and heat dissipation characteristics. Nvidia also announced the Maxwell-based GeForce 840M and GeForce 830M and the GeForce 820M, which is based on Nvidia's older 28nm Fermi microarchitecture.
Nvidia says its GeForce GTX 880M and 870M will deliver high-end games such as Metro: Last Light, Assassin's Creed IV: Black Flag, Batman: Arkham Origins, and Call of Duty: Ghosts at 1080p resolution with "ultra" image quality at a minimum of 30 frames per second.
The GeForce GTX 860M and 850M will deliver those same games at that resolution with "high" image quality at a minimum of 30 frames per second.
Each GPU has the same set of features. There is Battery Boost power management, ShadowPlay video capture, GameStream, Optimus and Nvidia's discrete GPU. Some of these features currently exist in other Nvidia notebook GPUs, while others are entirely new. The one exception is that processors from the GeForce GTX 850M down will not support Nvidia's SLI dual-GPU technology.
