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

Intel is so much focused on the power output of the Core M die that they even designed a new PCH known as Broadwell PCH-LP which is focused on power.

Report: NVIDIA GeForce GTX 1070M and 1060M Specs Leaked

by Sebastian Peak |
www.pcper.com
The report comes via BenchLife, with the screenshot of GPU-Z showing the higher CUDA core count (though VideoCardz mentions the TMU count should be 128).
And of course, we all want graphics performance that impresses and a user interface that is smooth and reliable while enabling NEW experience that we haven’t even thought of in the mobile form factor.
A software layer that is supposed to enable higher multi-threading capability for graphics platforms could have potentially massive impacts on mobile gaming and design so I am eager to see hardware capable of implementing it.

NVIDIA Quadro M6000 Announced

by Scott Michaud |

I wonder what this means for the Tesla line, and whether we will see a variant of Maxwell with a large boost in 64-bit performance, or if that line will be in an awkward place until Pascal.
The memory, but not the cache, is capable of ECC (error-correction) for enterprises who do not want a stray photon to mess up their computation.

NVIDIA Announces Quadro M6000 & Quadro VCA (2015)

by Ryan Smith |

However the company is also pushing the use of Physically Based Rendering (PBR), a compute-intensive rendering solution that uses far more accurate rendering algorithms to accurately model the physical characteristic of a material, in essence properly capturing how light will interact with that material and reflect off of it rather than using a rough approximation.
However as FP64 compute is not widely used in graphics, this is not something NVIDIA believes will be an issue.

96, actually that's not so much.
How many cuda cores there are in this hardware?
