Asus Radeon HD 7770 DirectCU TOP 1GB Graphics Card Review

Asus use a large single fan cooler which coveres the majority of the card. The styling is simple but effective with four red stripes across the middle of the card and some subtle Asus branding. We can also see a black PCB which is immediately welcomed by us at eTeknix.

The large single fan includes 9 translucent fins and some more Asus branding in the center. Underneath we can see the large aluminium heatsink with connected heatpipes.

Another view gives us a further look at  the heatpipes steming from the top of the card. Also we find a single 6-pin PCI-Express power connector on the end of the card.

A single CrossFire connector is available for those wanting to combine this card along with a second HD 7770 for improved performance at a later date.

Finishing off with the rear I/O panel, we can see a single DisplayPort, one HDMI connector and two DVI ports, one being DVI-I and one being DVI-D. Being a 7000 series AMD card also means that this card has the ability and functionality for AMD Eyefinity for those wanting to run multiple displays.

A standard Radeon HD 7770 comes with a clock speed of 1000MHz on the GPU core and 1125MHz on the memory. Asus have managed to increase past these levels with this card with a GPU clock of 1120MHz and a memory clock speed of 1125MHz. This is a fantastic speed increase, though we have seen cards from other brands with higher memory clocks, but we all know that the GPU clock makes more of a difference when wanting boosts in performance. The rest of the specifications are as expected with 1GB of GDDR5 memory on a 128-bit memory interface.
