AMD's new Radeon RX 580 and RX 570 spotted

AMD isn't just attacking the high-end graphics card market with its upcoming Radeon RX Vega graphics card, but it will be refreshing its Radeon RX 400 series of cards with the new Radeon RX 500 series.

Now we have some photos of the purported Radeon RX 580 and RX 570, both without their coolers on. The Radeon RX 580 engineering sample features a new PCB design, with AMD surely making improvements over the not-so-great PCB on the Radeon RX 480, which created headlines with its power issues - that were quickly fixed with updates from AMD.

The new Radeon RX 580 features a single 8-pin PCIe power connector, which should let the RX 580 clock higher than the RX 480, offering 10-15% more performance. We should see AMD ship the Radeon RX 580 with 8GB of GDDR5.

AMD's second-fastest RX 500 series card is the refreshed Radeon RX 570, which will come in both 4GB and 8GB versions, which rocks a single 6-pin PCIe power connector.
