AMD Radeon HD 7970 GHz Edition: Taking Back the Crown

The benchmarks are in for the Radeon HD 7970 GHz Edition. Starting at $500, AMD's new single-GPU flagship boosts theoriginal 7970's clock speed from 925 MHz to 1 GHz (1050 MHz with Boost). The GHz Edition also sports 3 GB of faster 1500 MHz GDDR5 memory, pushing 288 GB/s as opposed to 264 GB/s. While the AMD reference board runs hot and loud, retail boards will use different cooling solutions. A simple test of aftermarket GPU coolers shows that any other option will shave degrees and slash decibels. But it's the Catalyst 12.7 beta driver that really steals the show for AMD, pushing FPS scores into overdrive. With the new Catalyst, Nvidia's GeForce GTX 670 can no longer beat the original Radeon HD 7970, and the GHz Edition outmaneuvers the GeForce GTX 680 in most cases. However, when factoring price and possible overclocking into the equation, the original Radeon HD 7970 and GeForce GTX 670 remain the high-end graphics cards to beat.
