AMD's new RX 500 series promises affordable, yet capable gaming performance

PowerColor Radeon RX 580

We will bring the complete specifications of the AMD Radeon RX 500 Series graphics card once information becomes available.

Coming back to the RX 500 has been revealed in four variants - RX 550, RX 560, RX 570, and RX 580. The difference between the RX 500 series and the AMD's older RX 400 series is more or less 150 MHz. 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. Boost and base reference clocks are 1244MHz and 1168MHz, respectively, and cards will have 4GB of GDDR5 memory (7Gb/s) riding along on a 256-bit interface. On the RX 570 the gap is even bigger since the new card features Core/Boost frequencies of 1168/1244 MHz while the previous model clocked at 926/1206 MHz. This also explains why the new dual-fan reference card has a new board with a single 8-pin power connector and an on TBP to 185W.

The RX 560 and RX 570 are both iterative improvements of the RX 460 and RX 470 GPUs AMD launched almost a year ago. The RX 480 only made its debut in June of 2016, but the Radeons are moving up the flagpole, and we have an Asus Strix RX 570 in our hands, with the test results to prove it. While RX 560 has full Polaris 11, i.e. 1024 cores vs 895 cores on RX 460, the RX 550 has a cut-down Polaris 12. As part of the RX 500 announcement, AMD's also adding Radeon Chill support for League of Legends and Dota 2-two of the most-played games on the planet.

The most notable news is the way-cheap entry-level RX 550, which will start at $80 when it goes on sale in a couple of days. You can actually buy the things, for one-the RX 470 and RX 480 were understocked (and therefore, overpriced) for months.

According to TechFrag, AMD might unveil its high-end HBM2 (high-bandwidth memory) powered graphics cards in 4GB and 8GB options using its Vega architecture in the next few weeks.

In essence, RX-500 is a refresh of the existing RX-400 series, which is something not so uncommon in AMD's strategy.

The NITRO+ RX 580 and 570 cards also feature NITRO Glow - a stylish RGB LED backlight on the side, easily controlled with SAPPHIRE TriXX 3.0 software.

AMD's Polaris 20 GPU is comprised of approximately 5.7 billion transistors and has a die size of 232 mm2, just like Polaris 10. The "older" RX 480 Red Devil PCB and cooler are now used on RX 570 Red Devil graphics card. Despite the manufacturing process maturity, the higher clocks came with a price, since both RX 580 and RX 570 also have a higher power consumption.

The version we're testing today is Gigabyte's $180 Aorus Radeon RX 570, and it's a swanky one. Along with the RX 580, the RX 570 will be available starting today.
