VisionTek Radeon HD 7950 3GB Video Card Overclocked Review

The Card




At launch we saw two designs when it came to the HD 7950. The first was that typical design we're used to seeing which sees the fan down the back that pushes air across the GPU and straight out the back of the case. The other is the design we can see above where the fan sits directly over the GPU in the middle.






Taking a quick spin around the video card everything is as you'd expect, we've got two 6-pin PCIe power connectors at the back of the video card while closer to the front we've got two CrossFire connectors along with the dual BIOS switch.




The I/O side of things sees a Dual Link DVI connector, HDMI port and two mini DisplayPort connectors. A typical HD 7950 setup that we see most companies use, be it on a reference design or custom designed model.





The VisionTek HD 7950 as you probably expect follows with it just the reference clocks. Looking below you can see that means the core comes in at 800MHz while the 3GB of GDDR5 memory carries a clock speed of 5000MHz QDR.




Looking above, you can see what we ended up pushing the video card to as far as clocks go. We managed a healthy plus 300MHz on the core which equates to 1100MHz while the 3GB of GDDR5 was pushed up to 5600MHz QDR. This is a strong overclock and should yield some excellent performance.
