AMD might be releasing the HD 7790 graphics card which may be based on the Bonaire XT GPU.
As stated in our earlier clarification of AMD's 2013 Radeon plans, AMD will be releasing the HD 7790 graphics card in April to bridge the gap between the HD 7770 and HD 7850. Fudzilla further stated that the card would surprisingly be based on the Bonaire XT GPU and therefore be the first AMD GPU to be based on the GCN 2.0 architecture that is expected to power the upcoming HD 8000 series of graphics cards.
Fudzilla also indicated that the HD 7790 will be a very impressive performer, so much so that AMD has apparently asked manufacturers not to release overclocked versions of the card for fear of it surpassing and consequently crippling sales of the HD 7850. This implies that the Bonaire XT GPU holds a lot of potential for overclocking, something that we are always exited to see.
The HD 7790 isn't expected to make an appearance at CeBIT next month, but the company does plan to show off some of its other products to keep customers and shareholders happy.
