Making a new thread since this has been buried in others that are no longer being followed. AMD is pretty much covering all the bases this generation with a product for every performance and price bracket. All of these chips are GCN based, which says a lot about how scalable the new architecture is. As reference the 7870 should have performance on par with the 6970. Everything else under the 7750 is a rebrand of the currently available VLIW5 products and will only be available to OEMs.
