HIS has added two RX 500 series cards to its portfolio, one of which has one of the highest factory-overclocked boost clocks we've seen yet. The RX 580 XTR IceQX2 Roaring Turbo carries a 1430 MHz boost clock in Turbo Mode, as well as a 1411 MHz (at the level of Sapphire's Nitro+ Limited Edition RX 580) in OC Mode. The memory clock is set to a standard 8 Gbps (which is something I really don't understand, with the amount of headroom these usually have.) The board has one each of a 6+8pin power connectors so as to power this power-hungry card (relative to its performance, at least.)
