AMD's Hawaii GPU has been around for quite some time, but now we have a new and quite interesting rumors which suggest that the Hawaii XT GPU behind the AMD's current flagship R9 290X is actually a cut down version of the full chip which apparently features a total of 48 Compute Units or 3072 Stream Processors.
The rumor comes from DG's Nerd Story site, which was actually the first one that leaked R9 290X and the R7 260X graphics cards and suggests that, according to a die shot, the Hawaii GPU actually has 48 Compute Units, 192 Texture Mapping Units and 64 Raster Operators. This adds up to a rather impressive number of 3072 Stream Processors, an amount that was earlier limited only to dual-GPU graphics cards, the HD 6990 and the GTX 690.
According to DG's Nerd Story site, when 44 CUs is applied for Hawaii GPU, you end up with around 410-415mm2 die size which is smaller than earlier revealed 438mm2 die size. When 48 CUs is applied to the equation, you get around 438mm2 which means that AMD's flagship, the R9 290X, actually ships with a cut down version of the AMD Hawaii GPU and it is possible that we will see the Hawaii XTX GPU sometime in the future.
