The first specs of AMD's upcoming little brother of the awesome Radeon HD 7970 have leaked out, thanks to Turkish tech site Donanim Haber. AMD, of course, does not comment on rumors, but the site's source states that the cut-down Tahiti boards will ship with the same 384-bit memory bus that featured in the HD 7970.

To get the price lower than its bigger brother, the card will launch in two configurations: 1.5GB and 3GB. Core clock speeds also drop from 925MHz to 800MHz and the GDDR5 memory speed from 1.375GHz (5.5GHz effective) to 1.25GHz (5GHz effective).

At the moment, we don't know if the HD 7950 1.5GB/3GB will sport the same number of SIMD engines and stream processors as its higher-end equivalent, if it does, it might be the pick of the bunch when it comes to overclockers. Donanim Haber's source goes on to say that launch pricing of the HD 7950 3GB model will be $100 to $150 cheaper than the top-end 7970 3GB. AMD are of course keeping quiet on the situation, but a $100 - $150 cheaper card, capable of being overclocked sounds very nice indeed.
