Bringing the low-end market up to par.
In all the hoopla over the last few weeks with the Kepler launch, I overlooked a rather interesting card from AMD that also launched recently. While not quite in the same category as the other mid-range to high-end cards I have recently reviewed, the HD 7700 series nonetheless deserves a look over. True, I wasn’t much impressed with the AMD HD 7750, but the HD 7770 presumably improves the situation somewhat. So with much hopes, today I’ll be looking at the Gigabyte HD 7770 graphics card.
Layout & Cooling
The Gigabyte HD 7770 OC, as the name implies, comes with a factory overclock. What we have here is 1100MHz on the Core clock, up from 1000MHz from reference AMD speeds.
The overclock is obviously a result of the custom heatsink Gigabyte has put on top of the Cape Verde GPU. The large metal (presumably aluminum) heatsink has multiple fins spreading out; kept cool with a large fan that’s mostly quiet.
Measuring a total of 21cm, this card requires one 6-pin power connector with a minimum 450W PSU for smooth operations. Inside the packaging you’ll just get the (outdated) driver CD and installation instruction manual.
