PowerColor HD 7770 & HIS HD 7750 iCooler
PowerColor HD 7770 1GB
Simply put, the PowerColor card sent to us retained the reference design, right down to the heatsink installed over the core. It includes a single intake fan as well as a branded shroud that differs a bit from the standard glossy AMD colour scheme but is otherwise bone stock.
The only area in which PowerColor’s card differs from the reference design is their use of a red PCB. Otherwise, everything from output connectors (a mini DP to DP adaptor is included in the box) to fan choice is in line with AMD’s original specifications.
HIS HD 7750 iCooler
Like all of AMD’s board partners, HIS has decided to do away with the lackluster reference cooler and install their own cooling solution. In this case, it is nothing more than a single slot heatsink topped by a basic fan and a clamping system that tends to fall off if manipulated the wrong way.
Other than the “iCooler”, HIS sticks with the standard PCB, clock speeds and video outputs for this card. Don’t expect any adaptors either since the HD 7750 comes with full size HDMI, DisplayPort and DVI connectors.
