The Card

 

Having a look at the card we can see that it's pretty mid-range looking and one of the first things we notice is that the card's not quite as long as its higher end brothers. We can also see that GIGABYTE has opted for a smaller cooler that doesn't take up a huge amount of space on the card.

Having a closer look at the cooler, we can see that there isn't a whole lot to it. Apart from the fan that sits on top and the shroud that goes around it, below it we can see a heatsink that sits directly on the on the HD 4770 core.

Having a look around the card, we can see at the back we have a single 6-pin PCI-E power connector that is used to power the HD 4770. Closer to the front of the card we have our Crossfire connectors that let us run up to three of these cards together.

Looking at the front of the card, we've got two Dual-Link DVI connectors and a single TV-Out port in between. As we saw earlier, HDMI is offered via a DVI to HDMI connector that's included in the bundle.

 

Specifications

 

While the HD 4770 stock clocks are 750MHz on the core and 800MHz on the memory, GIGABYTE has decided to ramp up the memory clock to 850MHz. The big thing about this card is that while it's mid-range and carries a 128-bit memory bus, it does utilize 512MB of GDDR5 memory which is something new.

The biggest feature of the card would have to be the manufacturing process on the GPU. Utilizing 40nm technology the card should run nice and cool while also drawing less power. The 40nm technology will also ultimately mean higher clock speeds thanks to less heat, which is always a good thing.
