PowerColor DEVIL13 HD7990 Video Card Review

PowerColor has beaten AMD to the punch with its own creation of a dual-GPU Radeon HD 7970 CrossFireX solution in a single video card package. We evaluate this awe inspiring video card and of course overclock it to its highest potential. We put it up against the best GTX 680 SLI solution also overclocked, all with the latest drivers.


Evaluation Method

We evaluate what each video card configuration can supply us in terms of a playable gaming experience while supplying the best culmination of resolution and "eye candy" graphical settings. We focus on quality and immersion of the gameplay experience rather than how many frames per second the card can get in a canned benchmark or prerecorded timedemo situation that often do not represent real gameplay like you would experience at home. Then we will follow with apples-to-apples testing in with minimum, maximum, and average framerates.

Test System Setup

We will be using an ASUS P8Z77 WS motherboard. This motherboard supports PCIe 3.0 spec. For the CPU we used an Intel i7 3770K at 4.8GHz. The RAM is 8GB at 1600MHz.

Drivers and Video Card Setup

For the PowerColor DEVIL13 HD7990 we are going to compare it at its default clock speeds as well as its "Turbo" clock speeds. We are using the latest driver possible, AMD Catalyst 12.11 Beta8 released on November 16th, 2012. Note that this is BETA version 8. We are also using the latest CAP, which is 12.10 CAP 1.

For comparison, we are going to use two GALAXY GeForce GTX 680 GC video cards with SLI enabled. Each of these video cards cost $479 right now, with a rebate making these $459 each. At $479 each these come within $42 of the DEVIL13. At $459 they come within $82 of it. This is the closest competition and pricing to the DEVIL13 so it makes a great comparison. The GALAXY GTX 680 GC video cards have a factory overclock, these run at 1111MHz base clock or 1176MHz boost clock. In our evaluation of these video cards we found out they reach a real-world clock speed of 1215MHz in games.

We are using ForceWare 310.54 Beta driver released November 12th, 2012 for the GALAXY video cards.
