Having successfully launched their first 28nm GPU last January, AMD went on to release an entire family of Radeon HD 7000 GPUs over the next few months. The last of the series were the Radeon HD 7870 and 7850 graphics cards, which were closely followed by the launch of Nvidia’s next generation flagship part, the GeForce GTX 680.
It didn't take long for the GTX 680 a.k.a. Kepler to knock the Radeon HD 7970 off its perch, becoming the world’s fastest single GPU solution. AMD attempted to lessen the blow by cutting pricing of their 7900 and 7800 series lineups. Yet in the end, perhaps the best news for AMD came from the almost complete lack of GTX 680 stock.
Fast forward to the present day and it'd appear that AMD is desperate to claim the bragging rights of offering the single fastest GPU money can buy. As the name suggests the Radeon HD 7970 GHz Edition features a core clock speed of 1GHz, along with overclocked GDDR5 memory running at 1500MHz. AMD plans to charge a small premium for the GHz cards at $499, but is it worth it?
