A total product architecture is a combination of one or more slices with additional front end logic for command submission, fixed function hardware for 3D and media pipelines as well as a dedicated graphics technology interface (GTI) for accessing the rest of the components on the SoC.

Intel Skylake Gen9 Graphics Architecture

by Ryan Shrout |

Oh, and let’s not forget that many implementations of Gen9 graphics on Skylake will take advantage of DDR4 for primary system memory rather than DDR3.
A total product architecture is a combination of one or more slices with additional front end logic for command submission, fixed function hardware for 3D and media pipelines as well as a dedicated graphics technology interface (GTI) for accessing the rest of the components on the SoC.

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.

Sapphire launches new line of AMD R-Series video cards

by Charles Gantt |
www.tweaktown.com
The 270X series supports 1080p resolutions and Direct X 11.2.
Additionally a 280X Dual-X cooler edition has been announced that features the two Aerofoil fans, and heat pipe technology.
The Sub-$199 price market has been flooded with new cost effective solutions from AMD with the R7 series and NVIDIA couldn’t just leave the whole market alone since that is basically the cash cow for both companies.
The Radeon R9 270X is $50 cheaper yet a bit slower while the R9 280X based on the Tahiti XT chips is a bit faster yet $50 more expensive.
