Apart from showing its seventh generation of APUs, AMD granted a first look at its upcoming graphics cards based on the new Polaris architecture at the Computex. AMD officially presented the Radeon RX 480, set to be launched on 29 June. The launch officially confirmed the rumoured name of the card. The price is quite a surprise: the Radeon RX 480 will be available for 199 US dollars, while offering the performance of a 500 US dollars graphics card.
In terms of performance, AMD claims more than 5 TFLOPS computing power in single precision. As for the architecture, the chip company only wanted to reveal it has 36 CUs. If the card continues to have 64 shader units per CU, this would result in 2,304 shader units total for the Radeon RX 480. AMD also didn't reveal the clock rate. In theory and based on the computing power, 36 x 64 shaders would result in a clock rate of around 1,200 MHz.
The Radeon RX 480 will appear with 4 or 8 GB of GDDR5, connected through a 256 bit wide memory interface. At a clock rate of 2,000 MHz, this would results in a memory bandwidth of 256 GB/s. AMD states a power consumption. Freesync support ought to be mandatory, as well DisplayPort 1.3/ 1.4 outputs. This had already announced a few months ago.

With a price of 199 US dollars the new card would cost as much as a Radeon R9 380X or GeForce GTX 960, while having a significantly higher level of performance. AMD as of yet gave no details on the card's performance, but did say it ought to be on the same level as current 500 US dollar cards. As such, it would compete with the GeForce GTX 980, and above.
It also isn't all too much of a surprise that the new AMD GPUs are manufactured in the 14nm FinFET process. Globalfoundries will presumably manufacture the chips in its new 14 nm fab in upstate New York. The Radeon RX 480 AMD will support Async Compute, multi-GPU systems, i.e. Crossfire and anticipated technologies such as the Vulkan API and HDR video. Even games are expected to benefit from HDR in the future. AMD collaborated with the developer of DOOM, among others. The id Tech 6 engine will support HDR. Support of Vulkan is expected for the next update.
"The Radeon RX series efficiency is driven by major architectural improvements and the industry’s first 14nm FinFET process technology for discrete GPUs, and could mark an important inflection point in the growth of virtual reality,"stated Patrick Moorhead, an analyst at Moor Insights & Strategy.
Benchmark comparison between 2x Radeon RX 480 und 1x GeForce GTX 1080
AMD finally did give in to the temptation of some sort of comparison, and showed two Radeon RX 480 in a Crossfire configuration go toe to toe against an NVIDIA GeForce GTX 1080. The Crossfire double team was slightly faster running Ashes of the Singularity under DirectX 12, while the price is far, far lower. Considering the fact that a multi-GPU setup will be more difficult to implement with DirectX 12, this comparison is risky, but also due to other reasons.
For a price of 199 US dollars, AMD has set itself up entirely new, targetting the so-called sweet spot in the mid-range of the market with the first Polaris graphics card. Here, most graphics cards are sold and AMD appears to have done something absolutely economically viable. Customers will also stand to benefit. AMD sees the Radeon RX 480 with its price of 199 dollars as a sort of door opener for entering the realm of PC gaming, and thanks to its performance also for the use of VR headsets like the HTC Vive, or Oculus Rift.
AMD calls this its "Water Drop" strategy. Specific markets are focussed, and a product tailored exactly to the respective needs is launched. The strategy is supposed to win back market shares - a trend AMD has gladly accepted in the last few months.
"VR is the most eagerly anticipated development in immersive computing ever, and is the realization of AMD’s Cinema 2.0 vision that predicted the convergence of cinematic visuals and interactivity back in 2008," said Raja Koduri, senior vice president and chief architect of AMD's Radeon Technologies Group. "As we look to fully connect and immerse humanity through VR, cost remains the daylight between VR being the purview of the wealthy, and universal access for everyone. The Radeon™ RX Series is the disruptive technology that adds rocket fuel to the VR inflection point, turning it into a technology with transformational relevance to consumers."
