5.8 Out of 10

These chips are still based on Kepler (600-series), but feature more CUDA cores, more memory, a wider memory bus, and faster clockspeeds.

Combined with AMD's ZeroCore and Power Gating technology, the HD 7000M series is setting up to be a very power efficient platform.

In The News From around the web

A GM204 Quadro K6000 replacement, would be perfect for Nvidia’s value chain, unless they decide to go with GM200 directly.
Here is an example, the mobile variants usually have the m suffix, so the technically correct naming of a randomly chosen Maxwell card would be Quadro M2200m but that is semantic redundancy and would be marketing folly.

NVIDIA’s GeForce 800M Lineup for Laptops and Battery Boost

by Jarred Walton |

This is partly being done in order to make the GTX 850M look better (i.e. marketing), but it’s also being done as a way to segment software feature sets – as we’ll see in a moment, the mainstream 800M GPUs do not support GameStream or ShadowPlay.
The good news is that you should have plenty of choices in the coming months, and not only are we seeing faster GPUs but many laptops are starting to come out with high quality 3K and 4K displays.
Sorry folks but unless I am wrong on this one, you wont be seeing Maxwell in 800M Series GPUs.
We also know that the epitome of the Maxwell architecture is power efficiency and Performance Per Watt.
Nvidia would also most probably release a 880M SLI Configuration which would be the king of mobile graphics for a year or so.
Details about Maxwell’s Mobility series surfaced a few days back and now predicted benchmarks have also surfaced.
