AMD just announced a beast saying “It’s the biggest improvement in our graphics IP in the past 5 years" -Scott Wasson. In further detail Scott Wasson stated, “It now has the capability to process more than twice as many polygons per clock cycle than we could in our previous generation.” 
 

AMD Radeon Vega
The all new AMD Vega is having new and improved Higher Bandwidth Cache and Higher Bandwidth Controller silicon which looks the most exciting and that's all related to moving outside of the limits of the graphics card's video memory. 

The revolution with AMD's Vega design is to break free of those limits. The High Bandwidth Cache and High Bandwidth Controller mean the GPU can now stream in rendering data from your PC's system memory or even an SSD, meaning it doesn't have to come via the card's frame buffer.

The AMD Vega architecture is capable of scaling up to a maximum of 512TB as the virtual address space available to the graphics silicon. AMD are calling Vega “the world's most scalable GPU memory architecture.” In the network storage department, DRAM and NV-RAM. All, memory is not in close proximity to the GPU. Which enables the memory architecture to support up to a 512TB virtual address space.

Vega NCUs have been designed to execute more instructions per cycle and operate at higher clock speeds. Which means that any given NCU can finish more work in a single cycle than before AND go through more cycles in one second.


The new design is also capable of executing half precision compute work at double the rate of single precision compute and quarter precision compute work at four times the speed of single precision. All of these factors combined make it considerably faster and more power efficient than ever before.


AMD have already confirmed that they will be releasing Vega graphics cards in the first half of 2017 which brings the release dates to the end of June.

There will be different levels of AMD Vega GPU. The top card may not get a 500-series designation – that could be their new AMD RX Fury. The price for their flagship GPU could be anywhere between $800 to $1,200.
