GIGABYTE Radeon HD 7790 1GB OC Overclocked Video Card Review - The Card and Specifications

GIGABYTE Radeon HD 7790 1GB OC Overclocked Video Card Review
With a new GPU model from AMD we're got some different versions of the new Radeon HD 7790 and today we look at one from GIGABYTE and overclock it.

The Card




We've got quite a large fan that takes up majority of the cooler with the help of the shroud. GIGABYTE have opted for a really larger cooler here with the Triangle Cool fan coming in at 100mm. This is large and due to that it should be able to spin quite low, while also offering some good cooling numbers.






Taking a look across the top we've got the same setup as the Sapphire HD 7790 1GB Dual-X OC we looked at the other day. That means towards the back we've got a single 6-pin PCIe power connector and closer to the front we've got a single CrossFire connector allowing for up to two of these video cards to run together.




Finishing our look you can see we've got two DVI connectors, one Dual-Link DVI-D connector along with a DVI-I connector. We've also got a HDMI port and a DisplayPort to round off the connectivity side of things.





Out of the box a reference clocked HD 7790 comes with a 1000MHz core and the 1GB of GDDR5 at 6000MHz QDR. While GIGABYTE has decided to leave the memory clock alone, they bumped up the core to 1075MHz. This is the same core clock as the Sapphire - the difference between the two cards in clocks is that Sapphire pushed the memory speed to 6400MHz QDR.




Because we had a look at an overclocked card already in the Sapphire HD 7790 review, we thought that we'd take the chance to overclock via MSI Afterburner. Because we don't have the ability to adjust the core voltage, we thought that we might not get much in terms of final overclocks. However, looking above, you can see the 1230MHz core and 6700MHz QDR memory clock paint a solid picture of strong overclockability.
