  • 2 GB GDDR3

Their architecture is best suited for a gigantic bundle of similar calculations (such as a set of operations for each entry of a large blob of data).

The results look good for Vulkan as it beats OpenGL across the board as you can see in the review.

Red matter and green blood; Vulkan runs on Linux

by Jeremy Hellstrom |
www.pcper.com
This new AMD Linux driver holds much potential and the closed-source bits are now limited to user-space, among other benefits covered in dozens of Phoronix articles over recent months.
The results look good for Vulkan as it beats OpenGL across the board as you can see in the review.

Tokyo Tech Goes Green with KFC (NVIDIA and Efficiency)

by Scott Michaud |
www.pcper.com
GPUs are very efficient in terms of operations per watt.
Their architecture is best suited for a gigantic bundle of similar calculations (such as a set of operations for each entry of a large blob of data).
Though much like the Xeon Phi powered Beacon, SANAM is a relatively modest supercomputer; its 2351.1 MFLOPS/W efficiency being spread among only 179KW of total power consumption (making it #52 on the Top500).
Altogether Beacon hit 2499.44 MFLOPS/W, nearly 400 MFLOPS/W higher than the BlueGene/Q computers it has surpassed.

Report: Nvidia to Give Green Light for Video Card Designs

by Wolfgang Gruener |
www.tomshardware.com
The approval will not be given if certain noise, power, voltage and heat levels are not met.
Apparently, Nvidia is enforcing its Green Light program, which requires graphics card makers to send in their designs for Nvidia's approval.
