Sapphire Radeon HD 6790 1GB Video Card Review - Card and Specifications

With the high end market taken care of, AMD begin to concentrate on some more budget friendly models with the new HD 6790. We look at Sapphires to kick things off!

The Card




Head on there's nothing too crazy going on with the card. The cooler design isn't really anything new and we've seen similar designs from Sapphire over the years. Behind the fan, though, we can see a couple of copper heat pipes that protrude straight out from where the core sits.


This isn't the reference cooler; like most mid-range models, partners have been able to attack the card straight away with their own design.




It's a little bit of a shock to see two 6-Pin PCI-E power connectors at the back. As we mentioned on the first page when looking at the bundle, it's not so much that the card carries two PCI-E power connectors, because that's not uncommon; it's more so that a real mid-range card like the HD 6790 carries two. AMD has told us, though, that some companies will be offering two, while the reference design only offers one. It's all very interesting none the less.






Closer to the front we've got a single CrossFire connector and connectivity is strong with a Single-Link DVI, Dual-Link DVI, HDMI and DisplayPort connector.




Specification wise, the HD 6790 doesn't look too bad at all. We've got 800 Stream Processors, 40 Texture Units, 16 ROPs and 64 Z-Stencil. At default the card carries with it 1GB of GDDR5, but more impressive is the fact it's on a 256-bit memory bus. Note below that some of the details are a little different, as GPU-Z didn't want to play nice with the card.




Clock wise we've got 840MHz on the core and the 1GB GDDR5 comes in at 4200MHz QDR. Overall it's not a bad looking card, and you do feel like there's going to be a bit of power on offer due to the fact we've got two power connectors there. It will be interesting to see how the model performs, that's for sure.
