The Card

Looking at the card, the first thing that really stands out is the dual fan setup which is something we've seen on recent Sapphire cards. It's proven to do a good job of keeping the card cool while also being fairly quiet. You can also see just behind the fans a look at the copper heat pipes which should hopefully serve us well.

 

The shroud design is really nice. While overall quite simple, it's quite aggressive when it comes to the lines. I would've loved to have seen Sapphire put some color on the cooler to make it really stand out.

Taking a quick spin around the card, you can see power comes in the form of two 6-Pin PCIe power connectors while closer to the front you can see we've got a single CrossFire connector giving us the ability to run two cards in CrossFire.

Checking out the I/O side of things, we've got the stronger options on offer. That means we've got a Dual-Link and Single-Link DVI connector along with a full size HDMI port and two Mini DisplayPort connectors.

 

 

Specifications

 

As we mentioned in the introduction, the card we're looking at today does come with the "Overclocked" tag and below we can see the clock speeds the card comes in at. Looking at the core, we can see that comes in at 920MHz which is 20MHz up on the default 900MHz HD 6870 clock.

Unfortunately the 1GB of GDDR5 hasn't been changed and that remains at 1050MHz or 4200MHz QDR. It would've been nice to see Sapphire overclock the memory as it would help boost overall performance a little more, but we do always have the ability to do it ourselves.
