The Hawaii GPUs will reportedly make a return in the 300 series. Featuring 8GB of memory as standard and increased core and memory clocks. The final name designated for 300 series based Hawaii cards hasn't been confirmed yet. But Videocardz.com reports that there will be two Hawaii based cards in the 300 series.



One will feature an enhanced version of Hawaii Pro and the other will feature an enhanced version of Hawaii XT.

Currently Hawaii XT powers the R9 290X and Hawaii Pro powers the R9 290. Both updated versions of the GPU will feature increased memory and GPU clock speeds compared to their R9 290 series predecessors. Both new iterations of the enhanced Hawaii GPU will feature memory speeds of 1500Mhz, a 250Mhz increase over the R9 290X and R9 290. The GPU clock speed for the new Hawaii XT is 1050Mhz, a 50Mhz improvement compared to the R9 290X. While the enhanced Hawaii Pro will feature a GPU clock speed of 1010Mhz, a 63Mhz improvement over the R9 290.

8GB R9 300 Series AMD Hawaii GPUs Leaked

The most interesting piece of information is that Videocardz claims both 300 series Hawaii based graphics cards will feature 8GB of memory as standard. That was not expected, especially since some rumors which were circulating around suggested the possibility that Fiji would debut with 4GB of memory as opposed to 8GB. However if Hawaii based GPUs will feature 8GB of memory as standard then it stands to reason that their higher-end, bigger brother Fiji would feature at least the same amount of memory and not less.

Interestingly, Fiji will most likely not debut under a 300 series name and would instead have a unique brand. That's because AMD rebranded Tonga , the R9 285, as the R9 380 for OEMs. Which means that when Hawaii, R9 290 series, debuts as the R9 390 series in its "enhanced Hawaii" form this would leave no room for Fiji in the nomenclature. So it remains to be seen how AMD will attempt to solve this dilemma.

We covered five days ago a report which indicated that the new flagship Radeon based on the Fiji GPU with stacked HBM VRAM will launch on the 24th of June. While other 300 series cards will debut approximately a week prior.

AMD promised that gamers will be able to choose from "multiple" Fiji powered boards with different form factors and cooling. The image you see above is only of those multiple. It features water-cooling and a very small form factor, resembling that of the Nvidia GeForce GTX 750 Ti cards and other mini-itx graphics cards.
