CHIP DESIGNER AMD has ramped up the clock speeds on its Radeon HD 7970 GHz Edition graphics card to compete with Nvidia's Geforce GTX 680.
AMD's Radeon HD 7970 graphics card was nothing short of a performance revelation thanks to the firm's Graphica Core Next (GCN) GPU architecture. However the company fell slightly behind Nvidia's Kepler-based Geforce GTX 680, thanks in part to higher factory clock speeds on Nvidia's video card, something the firm has claimed to have reversed with its Radeon HD 7970 GHz Edition.
As AMD's branding suggests, the Radeon HD 7970 GHz edition clocks the GPU at 1GHz, a 75MHz increase from before, while running the 3GB of GDDR memory at 6GHz rather than 5.5GHz. The firm doesn't cite exact power figures but the standard Radeon HD 7970 has a TDP of 250W.
While AMD announced that its graphics card vendors will all stock Radeon HD 7970 GHz Edition cards from next week, firms such as Asus, MSI and XFX have been shipping Radeon HD 7970 boards with GPUs clocked at or above 1GHz for some time now. Nevertheless, AMD has been able to make hay out of its extremely overclockable GCN chips that are fabbed on TSMC's 28nm process node.
AMD said Radeon HD 7970 GHz Edition cards will arrive next week but it didn't say anything about pricing. However given that Nvidia's Geforce GTX 680 retails for £410 to £450, it is safe to assume that retail pricing will be in the same ballpark. µ
