ASRock's new line of Challenger series graphics cards made its debut today with the announcement of the Navi-powered Radeon RX 5700 Challenger 8G OC and Radeon RX 5700 XT Challenger 8G OC.
The ASRock Challenger graphics cards have a plastic, black shroud with white and yellow accents. They occupy two PCI slots and measure 281mm in length. The cooling system consists of four 8mm-thick copper heatpipes that carry the heat away from the GPU into a large heatsink, which partially extends beyond the graphics card's PCB. A pair of 10cm fans actively provide cooling. ASRock also adds a metal backplate to the mix to help amplify the card's tough look.
