3DCenter.org managed to get their hands on what appears to be an official slide that reveals more info regarding AMD's Hawaii GPU. The slide reveals a lot regarding the actual specifications and gives us insight into differences between the Tahiti and Hawaii GPUs.

While it does have a lot of similarities with the Tahiti GPU, including the same component hierarchy, Hawaii GPU also features four shader engines, which is twice the amount that the Tahiti GPU had. Since it has two more shader engines it also features more geometry processing power including four independent geometry processors, each with a tessellation unit, double the amount of ROPs and 11 Compute Units per shader. Each CU holds four texture memory units and 64 stream processors. When you add all things up, you end up with 64 ROPs, 176 TMUs and 2816 stream processors.

Another big novelty is the structure where four shader engines in the Hawaii GPU are tied in a unified command processing structure with 1MB of L2 cache and 512-bit wide GDDR5 memory interface. The rest of the features include PCI-Express 3.0 x16 interface, six display controllers, Crossfire XDMA, UVD, VCE and AMD's new TrueAudio hardware part.

We should be just a few days from the official launch of the R9 290X based on the Hawaii GPU and we are still missing the "official" price tag as well as the official performance of the new GPU, but for now, it all looks well on paper.
