HIS kicked off its Radeon HD 7800 series with a trio of graphics cards under its coveted IceQ family. These include the HIS HD 7850 IceQ X, the HIS HD 7870 IceQ X, and HIS HD 7870 IceQ iTurbo. The first two use proven IceQ X cooling solutions that have been used on previous-generation graphics cards by HIS, which have just different cooler shroud color-scheme of black+silver. The HD 7850 IceQ X features clock speeds of 860 MHz core and 1200 MHz (4.80 GHz effective) memory, in line with AMD reference clock speeds, while the HD 7870 IceQ X features 1000 MHz core and 1200 MHz (4.80 GHz effective) memory, also in line with AMD reference. Then there's the HIS HD 7870 IceQ iTurbo, featuring a gargantuan new cooling solution never before seen. This cooler uses an aluminum channel heatsink, to which heat is fed by four 8 mm-thick copper heat pipes, through which air is blown by a lateral-flow fan. Interestingly, this card, too, sticks to AMD reference clock speeds.
