Sapphire Radeon HD 4770 Arctic Cooling Video Card

Video Card


Looking at the video card we can see that Sapphire have decided to move away from the default cooler and install an aftermarket cooler from the folks at Arctic Cooling. Unlike higher-end video cards, the cooler doesn't take up the entire size of the PCB. The cooler isn't terribly exciting though - there's no heat pipes present, just a number of aluminum fins.




Since the cooler doesn't take up the whole PCB area, Sapphire have to use some heatsinks to cool some of the other parts that aren't covered by the cooler itself. We can see to the right we have three little heatsinks along with a longer one next to that which has the Sapphire name on it.






We can see a single 6-pin PCI Express power connector at the back and closer to the front we have two CrossFire connectors, which gives us the ability to put up to three of these cards together in a single system.




Having a look at the front of the card we can see that Sapphire have decided to mix it up a bit. Across the top we have our normal vents which help the hot air escape while below that we have a VGA connector and Dual-Link DVI connector. Between these two though, we have a native HDMI connector. This is the main reason we saw little few cables in the bundle with no TV-out present and no DVI to VGA connector needed.




When it comes to clocks we can see that Sapphire has chosen to do nothing leaving the default core and memory clock, which means we've got a 750MHz core clock and a 800MHz memory clock - of course being 512MB of GDDR5 that comes to 3200MHz QDR.




The other big feature that we can see is that 40nm technology is in use here. This combined with the GDDR5 memory makes the HD 4770 a pretty neat piece of equipment as far as tech goes.
