More and more rumors surface that AMD may be preparing to launch a GHz edition of its Radeon HD 7970. Current stock models are clocked at 925MHz, but recent chips seem to be able to hit 1.25GHz without struggling.

According to Australian site Atomic MPC, the company has revealed that the manufacturing process of its next-gen GPUs has improved to the point where the same average voltages can yield much higher clock speeds. Recent chips can reach 1.25GHz without struggling, which means a conservative "GHz Edition" of the 7970 can now safely be rolled out, of course with scope for much higher overclocking on third-party boards with more robust coolers. By the time the battle between Red and Green reaches full-swing, it might not be so easy to call a winner.

The new HD 7970 GHz Edition will come with reference core clock speed of 1050 MHz.
