At the inaugural AMD Fusion Developer Summit in June, 2011, Eric Demers and Rick Bergman looked Rage3D in the eye and promised the next generation of Radeon GPUs would launch at the end of 2011. Two of those three are with us as we move deep into the Yuletide season, with Rick Bergman now CEO of Synaptics, Inc. Before his watch ended, AMD’s graphics group put the final touches to their third generation DirectX 11 architecture, which is also one of many firsts – first to DirectX 11.1; first to 28nm process technology; first to over 4Bn transistors; first to feature some genuinely good power saving technology; and the first AMD single GPU product to return to the huge, monolithic expensive die price point of over $500USD – well over, in fact, at $549USD, but still at a die size smaller than the HD 6970 Cayman or HD 5870 Cypress chips.

Under the Southern Islands codename, the GPU core is known as Tahiti XT. The board sold by AMD’s Add-in Board (AIB) partners like ASUS, Sapphire, MSI et al, is known as the AMD Radeon HD 7970.
