[citation][nom]wdmfiber[/nom]I believe the 15-20% JJ1217 commented about was directed towards enthusiasts/techies. A rough, perhaps optimistic guess. As the 8000 series is/was just going to be a refresh/name change. Marketing really, ...but with better yields out of TSCM.These "new" GPU's will be based on the same 28nm technology, so the only way to get a good increase in graphical power would be to buy a 8000 series card that uses more electricity(watts) vs. the 7000 series card. Similar scenario to the Radeon 5000 & 6000, as they shared the same fab pocess (40nm).The real next generation will be the Radeon 9000's (Volcanic Islands) and nVidia 800's (Maxwell). As already mentioned by enewmen. Hopefully available sometime in 2014, but maybe not[/citation]
Architectural improvements can be made. For example, going from VLIW5 in the Radeon 5000 and 6700 and down cards from Radeon 6000 to the improved VLIW5 in the Radeon 6800 cards was a significant improvement in performance per watt on the same node with the same basic architecture, just tweaked somewhat. Also, although unlikely, an architectural re-haul like from VLIW5 to VLIW4 can also be done.
Furthermore, the article only tells us that the mobile Radeon 8000 graphics coming out are to be rebrands of Radeon 7000. Nowhere does it say that the Radeon 8000 desktop cards won't be improved over the previous generation in performance per watt and in no way is it impossible. Heck, if Titan is anything like what it's said to be, it's great proof of that.
