Card Layout and Pictures

The Sapphire HD 7790 Dual-X’s main feature is of course the Dual-X cooling. What that gets you is the two fan design that you can see below along with a cooling design similar to what we have seen from other non-reference designs. There is a heatsink that runs the length of the card with heatpipes that run from the heatsink to right on top of the GPU. This design helps spread the heat out over the larger cooler to make the dual fan design most efficient. To cover it all up Sapphire has covered it all up with a two tone plastic fan shroud that has an interesting edgy design that does a good job catching your eye. Being plastic this is a little less than what you get from XFX, ASUS, or MSI for example material wise.

From the top view we can see a few of the heatpipes going directly to the GPU to pull the heat out and onto the heatsink to keep things cool.

Even though most of the fan shroud does seem to funnel most of the air out of the case, the end of the card is completely open. This means that part of the heat of the card will also vent into your case. This is the price you pay with non-reference cooling generally, but it is something to keep in mind if your case has very limited ventilation.

The Sapphire HD 7790 Dual-X comes with a full sized display port connection, a full sized HDMI connection, and two DVI connections (one with analog support). Sapphire has also packed the back panel full of ventilation, slipping vents in between each connection and even a few short vents above the Display Port connection.

Here we have two things going on. First you can see that the Sapphire HD 7790 Dual-X has a single crossfire connection meaning it will be limited to dual crossfire. Also here we have a good look at the Sapphire logo on the top section of the fan shroud. It’s not huge or flashy and because of that it looks good. This is much better than the stick on Sapphire stickers that we have seen on some of their previous cards.

For power, much like the other HD 7790’s that we have tested the Sapphire HD 7790 Dual-X has a single six pin power connection to power everything.

Last but not least, if you take a look at the back side of the Sapphire HD 7790 Dual-X you will see that Sapphire went with a black PCB. This is a small feature that goes a long way when you remember that the back of the card in your case is what you see the most. It’s also interesting to see that the PCB has been extended simply just to line up with the Dual-X cooler, you can see that they didn’t mess with anything other than moving the power connection out slightly for clearance.
