AMD has a new range of graphics cards in the form the RX 580, RX 570, RX 560, and RX 550.

The rest of the GPU models - the RX 580, RX 570 and RX 560 - still don't seem to pose any challenge to Nvidia at the mid-to-high end of the range.

And, it's not designed for that - rather AMD explains it's introducing the RX 550 as a discrete graphics option for those putting together compact, fan-less systems - i.e. home theater PCs. The slight increase in clock speed (up to six percent for the boost clock and about 15 percent on average for the base clock) and the slight tweaks to the Polaris architecture that make it "second generation" don't inspire thrills, and mostly contribute to decreased power draw. The RX 570 has also seen a major bump in the base clock speed from 926 MHz to 1168 MHz.

Improved response times, more efficiency, and cooler operation with Radeon Chill - Radeon Chill is an advanced framerate controller for the Radeon RX 500 series that works automatically in the background (when enabled) to dynamically regulate framerates in today's most popular games based on the speed of mouse movements and the gamer's activity in a scene.

Its TBP has also been increased to 185W and that's the reason behind the higher clock speed.

The base/boost clock speed on the AMD Radeon RX 480 is 1120MHz/1266MHz. The RX 570, which aims for "maximum" 1080p gaming, will go for around $169, while the slightly slower RX 560 will start at $99. So far AMD has not revealed details on pricing and availability regarding their new series of graphics cards but we expect the prices to be a little bit higher than with the old RX 400 series. At reference clocks, the peak compute performance of the Radeon RX 570 is 5.1TFLOPs with 224GB/s of memory bandwidth. As you can see from the slides below, AMD Radeon RX 500 series will have all the latest AMD Radeon technologies including optimized DirectX 12 and Vulkan support, FreeSync, ReLive, Chill and HEVC H.265 4K Encode/Decode capabilities. These cards all require a single 8-pin power connector.

The Radeon RX 560 will reportedly field in a full Polaris 11 with 1024 cores compared to 895 cores on RX 460).

RX-580 is based on the same Polaris 10 core.

Priced at $229 (about £180, AU$300) for the 8GB version and $199 (about £160, AU$260) for 4GB, AMD is making a sweeping claim that it will 12% faster than any older $200-$300 GPU when it releases on April 18th.

The Aorus Radeon RX 570. This GPU was not available in the Radeon RX 400 series and AMD did not have a similar GPU since Oland-base Radeon R7 250. So if you're in the market for a new card, there's that.

We are only going to discuss the AMD Radeon RX 580 today because that is the video card we will be evaluating.
