Design & Features

The HIS Radeon HD 7750 iCooler comes packaged in a small box, decorated in traditional HIS styled sword cover art. The box measures 189x250x78mm and advertises its PCI-Express 3.0 specification, quad HD display support, and 1GB of VRAM.

The stock clocks of 800MHz Engine clock and 1125MHz memory clock are in place, exactly as the reference design.

The outer sleeve contains a flap-top box which contains the card itself, ensconced in crush resistant foam.

The card uses the reference AMD Cape Verde Pro PCB design, with standard output configuration of a single DL-DVI, full size HDMI 1.4a output and full size DisplayPort 1.2 output. Fast HDMI support allows the box-art claim of Quad-HD resolution support, enabling connections to 4096x3112 resolution TVs, the first of which were demonstrated a CES 2012 in January.

The single deviation from reference specification is the cooler, named iCooler. The iCooler features an aluminum heatsink with a large axial fan rated at 28dB in 2D mode. The fins extend over the memory, adding cooling capacity for overclockers. The heatsink and fan size makes the card a dual-slot design, unlike the reference slim single slot card.

AMD's GCN architecture brings support for DirectX 11.1, due to be launched with Windows 8. AMD's current preview drivers for WDDM 1.2, the display driver model used in Windows 8, don't yet support the new AMD Radeon 7000 series, so if you're wanting to try out the native Stereo3D support or other new feature you'll still have to settle on using an HD 5000 or 6000 series card instead.

Both the DisplayPort and HDMI 1.4a output support audio, including positional audio with per-display audio streams using the built in HD audio chip, which also supports Blu-ray protected audio path and multi-channel bitstream output. Fast HDMI 3GHz support offers 1080p60 3D with supported displays.

The Cape Verde design incorporates UVD 3 and AMD's new Video Codec Engine (VCE). VCE functionality has not yet launched, but is indicated to be shortly with new application versions and drivers enabling it. The GCN architecture QSAD instructions are present, accelerating AMD Steady Video 2.0 - an AMD exclusive platform feature.

All of AMD's GCN architecture cards feature Zero Core Power and PowerTune, offering precise control over load power and markedly reducing idle power. In the case of the HIS Radeon HD 7750 iCooler, the long idle (display blanked) power consumption is under 3W. Average board power is given as 55W, with AMD's PowerTune limiting max board draw to 75W even at the Overdrive customized +20% setting. Multi-GPU is supported over PCI-Express, with no external Crossfire connector required, and limited to 2-cards.
