Checking out the Sapphire HD 7790 2GB the first thing that comes to mind is just how sexy it looks. Alongside a new shroud design, which looks awesome, the black PCB looks fantastic too. You can see a large fan sitting in the middle and a couple heat pipes near the top.
You can see the standard 6-pin PCIe power connector at the back. Here, though, you also get to see the aggressive look of the shroud. Closer to the front you can see the typical CrossFire bridge that gives the ability to run two of these cards in CrossFire.
When it comes to the I/O, we've got two Dual-Link DVI ports - one DVI-D and the other DVI-I. We've also got the typical HDMI port alongside a DisplayPort.
As we mentioned earlier, the video card we're looking at today is an OC Edition model. Out of the box the standard HD 7790 comes with a 1000MHz core, while the 1GB or 2GB of GDDR5 comes in at an even 6000MHz QDR.
Looking above you can see that Sapphire pushed the core up to 1050MHz, while the 2GB of GDDR5 memory is pushed slightly to 6400MHz QDR.
This isn't a bad overclock and falls in line with most other HD 7790s we've looked at recently. To date we're still yet to test a reference clocked HD 7790 since most companies are releasing overclocked models straight out of the gate.
