ASRock has just announced the first custom 7nm RDNA based graphics card, their latest Radeon RX 5700 Challenger series. The ASRock Radeon RX 5700 challenger series aims to deliver better cooling performance over the reference design while offering a factory overclock.

The ASRock Challenger series is a completely new brand designed exclusively for the Radeon RDNA based graphics cards. There are two cards in the lineup, the RX 5700 XT Challenger and the Radeon RX 5700 Challenger. Both graphics cards feature the same design but the core specifications will be different.
