Curacao XT will have more stream processors as compared to the current flagship Tahiti XT. The new graphics core will also have more ROPs and TMUs, which are shown in the table below. The new card will have a same GDDR5 memory type and a size of 3GB, running through a 384bit memory interface. Other than knowing that the new Curacao XT is based on a 28nm manufacturing process for a GCN architecture, there are no other information shown on this slide.
This rumour is not in line with AMD’s roadmap. We are not sure if AMD will launch Curacao XT this year to compete with GeForce 700 series cards, or the GeForce 600 series. However, as these are all simply rumours and are not confirmed, it should be taken with a pinch of salt.
