With its factory overclock, PowerColor's Devil13 HD7990 6 GB comes very close to the GeForce GTX 690 in our performance-oriented tests. Meanwhile, HIS' 7970 X2, which was shown off at Computex, but not necessarily a sure thing, is finally ready. Elevated clock rates are supposed to make the HIS card the fastest graphics card, period. But do the benchmarks concur? Let's have a look at how these three boards stack up on paper first.
Technically, the HIS card looks like it holds a strong position. If those numbers translate into real-world performance, and if micro-stuttering isn't a problem for AMD, it could be winner. Then again, already saw in GeForce GTX 690 Review: Testing Nvidia's Sexiest Graphics Card that Nvidia put a lot of effort into creating a fast, svelte, and quiet offering in its GeForce GTX 690. That'll be a tough act to follow.
