It's been a long time since we've seen a video card from ASUS, but today we check out the new HD 7790 DirectCU II OC, and see how it performs.

The Card

We've got an attractive looking dual fan setup and you can see both the heatsink and heat pipe setup behind those fans. One thing we do love, and while subtle, is the black PCB that ASUS is using.

Having a look around you can see when it comes to the power we've got a single 6-pin PCIe power connector. Moving across the top you can also see the standard single CrossFire connector.

Looking at the connectivity side of things we've got two Dual-Link DVI ports - one is a DVI-D, while the other is DVI-I. Along with the two DVI ports you can see we've also got a HDMI and DisplayPort to round off the connectivity options.

 

 

Specifications

 

When it comes to the out of the box clock speeds the ASUS offering is in line with the Sapphire model, which means the core comes in at 1075MHz, and the 1GB of GDDR5 comes in at 6400MHz QDR. This compares to the GIGABYTE which carries the same core clock speed, but the reference 6000MHz QDR memory clock speed.

Since the clocks were the same as the Sapphire model we reviewed earlier, we decided to get into some overclocking. We managed to push the core up to 1230MHz, while the 1GB of GDDR5 was pushed just slightly up to 6560MHz QDR.

 

We'll find out what exactly this does for performance over the following pages.
