PowerColor RX 500 cards deliver fire and brimstone
 

PowerColor's cards based on AMD's ever-so-slightly refreshed Radeon 500-series silicon have been something of a worst-kept secret over the last few weeks. The company has now officially unveiled two Radeon RX 570 cards along with a quartet of RX 580 pixel pushers. The two RX 570s both pack 4 GB of 7 GT/s GDDR5 memory, while the higher-end cards carry varying amounts of memory at 7 GT/s or 8 GT/s depending on the model.
