MSI has stuck with the display output configuration of NVIDIA's reference design, with three DisplayPort 1.2 outputs, one dual-link DVI and one HDMI 2.0 output.

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).

NVIDIA Quadro M6000 Announced

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.

did u find anything for this prob?
I have a laptop with this GPU. Its very very bad. You can not use the power of this GPU because it underclock GPU from 500MHz to 100MHZ when the GPU temp go over 70. Intel HD Graphics 4000 is better because you cant use the power of Geforce GT 640M LE.
