After RV740, the next AMD venture on the 40nm silicon process will be the company's next flagship GPU: the RV790. With this core AMD hopes to reclaim the performance and value crowns, more importantly, energy efficiency the newer fab process hopes to bring to the current-generation GPU.
Quite obviously, AMD will assign new SKUs to the products based on the RV790. The safest guess would be the formation of a new sub-series under Radeon 4000, the Radeon HD 4900 series. German website ATi Forum has learned that indeed AMD planning on a new sub-series based on the new GPU, following scoops on RV740 making the Radeon HD 4700 series. Once again, AMD might create two products based on a single GPU and one flagship dual-GPU accelerator, to begin with. The company's lackluster optimism in the R700 Pro (Radeon HD 4850 X2), has shown on the upcoming series with no mention of a second-inline dual GPU accelerator. In ATi Forum's theory, the RV790XT gets HD 4970, RV790Pro gets HD 4950 and the dual-GPU flagship SKU could be named Radeon HD 4995 X2. Talk about competitive naming.
