In fact the information we have indicates that the full Hawaii GPU will go straight to FirePro model, whereas the 2560 edition will be used with the flagship Radeon. That's the rumor of course. I could not verify anything because AMD is very quiet about their new release.

4gb that means 512 bit? Interesting to see the result

Its a sample cooler. 99% sure its not the final cooler system

If it has a 512 bit bus, many here will have to eat their words.
That being said...Is it possible that it has 4gb on the front and 2gb on the back? I just can't make sense on how they would be able to fit 2,8k SP's, buffed up front and rear end AND a 512 bit bus

512 bit! nice.

The million dollar question is (imho) will the GPU core be powerful enough to utilize all that memory bandwidth and VRAM???

7970's generally don't have a problem as is pushing 3gb as most can easily get 1600mhz+ out of the mem and 1200 on the core. With the improvements made (assuming this is true) I don't see an extra gb really making a huge deal of difference as to handling it. Now that said, that's when you look at games with high res textures and mods - a game on let's say Crysis 3's level or above that also needs 3gb+ ram is another story and it will struggle a bit more, just as a 780 or titan would.

Bare in mind, though assuming it is a 512bit bus, the memory clocks will probably be lower, too. I'm pulling roughly 308gb/s bandwidth with a 1600mhz mem clock as is on a 384bit bus - a 512bit bus can match that with far lower clocks.
