Sapphire Radeon HD 7770

XFX & Sapphire HD 7770 1GB Review

In comparison, the Sapphire HD 7770 Overclocked Edition is roughly the same length as the XFX card, but doesn't appear that way due to its mostly-enclosed plastic shroud. The black plastic casing is textured and molded to give the card an aggressive look while shaped just right for the multiple copper heatpipes to show from the side. There is only one fan as opposed to two on the XFX card, but these heatpipes should compensate for the airflow difference. The card boasts the typical Sapphire blue PCB which matches the gold pins of the PCI Express notch and the copper color of the heatpipes well. Looking at the rear of the card, we can see the Sapphire logo on the other side of the plastic shroud and "leafed" in silver color. The bright blue PCB can be seen in full from this side, along with the traces and the rest of the components as well — including the Crossfire bridge port. Taking a look from the sides show that the black shroud is not fully enclosed, just like that of the aluminum cover of the XFX card. From these angles, you can see some of the internal components and get a better look at the heatpipe layout along with how they interface with the copper plate on top of the GPU die.
