Sapphire Radeon HD 7970 3GB Video Cards in CrossFire - The Card & Specifications

We got a new Sapphire HD 7970 video card into the labs and start to test CrossFire performance of the brand new HD 7970 GPU from AMD.

The Card

Moving away from the bundle and onto the video card you're going to notice the familiar look that's present thanks to the use of that reference cooler again. The only difference is of course the sticker that's installed which in this case has Sapphire HD 7970 written on it. The reference design is exactly what we want to use today since we want to run two of these cards in CrossFire.

Taking a quick look around the card you can see our two PCIe power connectors at the back in the form of a single 8-Pin and single 6-Pin. Closer to the front we've got our two CrossFire connectors which we'll be making use of today along with the BIOS switch we've seen on all the HD 7970s we've looked at so far.

Finishing off with the IO side of things finds two MiniDP ports, HDMI and a Dual Link DVI connector. The top half is of course a vent that helps let the hot air escape. While this overall fan design with this design tends to be a little louder, when moving to a multi GPU setup, the fact that it pushes the hot air straight out the back of the case, verse just pushing it around the case, tends to result in better cooling numbers.

 

Specifications

 

Firing up GPU-Z it comes as no surprise that the default clocks of the card are in line with the reference model and that means that the core comes in at 925MHz while the 3GB of GDDR5 memory carries a clock of 5500MHz QDR.

The main thing we want to look at above is to make sure that CrossFire is up and running and as you can see down the bottom under the CrossFire section, it's of course enabled via two GPUs, which is exactly what we want to see. Of course the only real way to make sure everything is working is to get into the benchmark side of things, before we do that let's just quickly look over our testbed.
