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.)HIS has also launched an RX 570 and one RX 580 IceQX2 (sans Roaring Turbo, which is something I feel like doesn't instill confidence on the cards' acoustics) with more standard cooling solutions, though the fans have been "upgraded", according to HIS, to an 11-blade design (as opposed to the RX 400 IceQX2 series' 9-blade design,) which should improve acoustics and airflow. There are two extra versions of the RX 580 (OC, with 1366 MHz boost clocks) and Turbo (with 1405 MHz boost clocks.) Its RX 570 IceQX2 card features 4 GB of GDDR5 memory, and a boost clock fixed at 1264 MHz. Interestingly, HIS seems to be the only AIB so far to overtly compare its own RX 400 and RX 500 offerings performance-wise, and it would seem power levels of these cards start at over 9000 (even if the performance difference is, per HIS themselves, a meager 9% away.)
