Expreview posts that AMD is working on a faster GHz Edition of its Radeon HD 7950 graphics card. By increasing the clock frequencies, the card should perform similarly to rival Nvidia's GeForce GTX 670, which according to our review, is about 14.9% faster than the HD 7950. AMD's first response to the release of the GTX 670 was to decrease the price of its Radeon HD 7950, which is now available at a price of about £300. Nvidia's GTX 670 and AMD's Radeon HD 7970, which are similar in performance, are priced around £330.
Recently, AMD launched a GHz Edition of its HD 7970 card, which turned out to be slightly faster than the GTX 680, on average. The same trick will now be applied to the HD 7950, the cheaper sibling that features 1792 shader units (of the 2048) and an 800 MHz clock frequency. Because the card is based on the same 28nm 'Tahiti' GPU as the Radeon HD 7970, there's plenty of margin for overclocking. A hypothetical 1 GHz version of the card could theoretically improve performance by up to 25%, if the memory bandwidth allows it that is. This should be sufficient to bridge the performance gap with Nvidia's GTX 670.
It's likely that the faster GHz Edition of the HD 7950 will require more power. It's still unclear what the price of the new card will be. VR-Zone writes that AMD's partners are allowed to design their own cheaper 'non-reference' PCB for the card.
