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.
While we already did a drop, scratch and water test to see if the smartphone could sustain a few hits here and there; iFixit’s One M8 teardown would show you what to expect realistically when you have a broken or damaged HTC One M8.
IFixit also notes that the repair work is made harder by the use of copious amounts of tape, adhesive, and copper shielding.
The 760M and 765M both use 768 CUDA cores, but the 765M is clocked almost 200MHz faster.
The RAM and core are connected via a 256-bit interface.

Nvidia announces five new Geforce 700M GPUs

by Slobodan Simic |

It is not clear how GT 740M ends up clocked higher than the GT 745M but it might have something to do with the maximum Boost.
All five new GPUs will feature Nvidia GPU Boost 2.0, Optimus and Nvidia Geforce Experience technologies.
