AMD HD7770 & HD7750 Roundup: Sapphire, XFX and HIS

We received two HIS HD7770 GHZ Edition IceQ X cards for review. I honestly think HIS need a complete design of their box art, it really is nondescript.

The bundle includes a single video converter, some literature on the product, an installation guide, and a software disc. A Crossfire bridge would be a worthy addition to this bundle in our opinion.

The HIS HD7770 GHZ Edition IceQ X is built around an Aqua coloured PCB and a large fan is placed just slightly offcenter. The new cooler is quite attractive and a step up from the translucent versions of yesteryear.

The card takes power from a single 6 pin PCI connector.

It is Crossfire capable in a two way configuration.

The card ships with a single DVI connector, a full sized HDMI connector and two mini DisplayPort connectors. Sadly HIS didn't bundle a convertor for these ports in the bundle.

The cooler is easily removed and features a tiny strip of direct touch copper to contact with the core underneath. It is a dual heatpipe design, with each heatpipe running into separate racks of aluminum fins on either side.

HIS are using Hynix memory on the HD7770 IceQ X.

The HD7770 IceQ X is marked as a GHZ Edition card on the front of the box, but the core speed has been overclocked to 1,170mhz, and the memory is configured to 1,250mhz (5Gbps effective). The 1GB of GDDR5 memory is connected via a 128 bit interface, which is a little disappointing as it will hamper performance a little. There are 16 ROPS with this design and the HD7770 receives a shader boost, from 512 to 640.
