Sapphire seems to have screwed up its roadmaps as it according to X-bit Labs has updated its Radeon HD 2000 assortment with information about the not yet announced HD 2900XTX. The list of graphics cards, where Sapphire has listed a Radeon HD 2900XTX, has been cleansed of any traces of AMD’s coming graphics circuit by now, but the information that was revealed yesterday by X-bit Labs was saved before it could be destroyed. According to the list from Sapphire, Radeon HD 2900XTX will have twice as much memory, 1GB, as AMD’s current flagship HD 2900XT. And we’re talking GDDR4 working at 2050MHz, a lot higher than XT with 512MB GDDR3 at 1650MHz.
Radeon HD 2900XTX will sport the same GPU frequency, 740MHz, as the XT model, which clearly points to that the XTX model will be based on the same “inefficient” 80nm process. Whether the huge memory buffer and its frequency will be enough to match the performance of NVIDIA’s flagship remains to be seen though, but apparently there will be more high-end cards from AMD before the 65nm respin.
