by www.tweaktown.com (Jan, 2016)AMD said that the Polaris architecture is a "historic leap in performance per watt for Radeon GPUs", and that has seen "significant" performance per watt improvements on early GPU samples and early software compared to the previous generation.
by Anand-Lal-Shimpi (Jun, 2013)Ray tracing has become a stronghold for GPUs in recent years as ray tracing maps well to GPU pipelines, allowing artists to render scenes much more quickly than with CPUs alone.
Features Key features of the Radeon Pro Duo Polaris
memory bandwidth Rate at which data can be read from or stored in onboard memory
pixel rate Number of pixels a graphics card can render to the screen every second
texture rate Speed at which a graphics card can perform texture mapping
floating point performance How fast the gpu can crunch numbers
shading units Subcomponents of the gpu, these run in parallel to enable fast pixel shading
texture mapping units Built into each gpu, these resize and rotate bitmaps for texturing scenes

AMD is promising some more fluid gameplay with RX 580 and Radeon Chill, thanks to fewer frames being queued to your display, you can reduce the response time of the frames being rendered by 64%, down to 6ms from 16.7ms..
The news headline cycle only cares about high-end products, but the sell through numbers on RX 560/550 are going to be huge in overseas markets like China, where there are tens of millions of gamers that would jump at a new $99 graphics card.

AMD said that the Polaris architecture is a "historic leap in performance per watt for Radeon GPUs", and that has seen "significant" performance per watt improvements on early GPU samples and early software compared to the previous generation.
Overall, I was impressed with what AMD discussed at RTG Technology Summit and the Polaris architecture as a whole.

A report claims that Polaris will succeed GCN (Graphics Core Next) as the next AMD Radeon GPU core, which will power the 400-series graphics cards.

Given the potential use as a very large CPU cache, it’s a bit insane that Intel won’t even offer a single K-series SKU with Crystalwell on-board.
iGPUs aren’t going to have quite enough power to use its marquee feature – DirectCompute accelerated hair physics (TressFX) – however even without it the game still looks quite good at its lower settings, while providing a challenge for our iGPUs.
