A few days ago the launch of the GeForce GTX Titan prompted AMD to announce the upcoming release of a number of new Southern Islands graphics cards scheduled for release later this year.
It seems the US chipmaker will keep its promise – in order to compete against NVIDIA’s increasing pressure and counter the delay of its Sea Islands GPU family (Radeon HD 8000 series) AMD will soon launch an updated mid-range graphics card that will be known as Radeon HD 7790.
The AMD Radeon HD 7790 will be the heir to the successful Radeon HD 7770 video card and will offer performance that will be close to that of the Radeon HD 7850. At the same time the newcomer will be cheaper than the HD 7850 but will be a little more expensive than the current HD 7770 offering. Still in order to keep the sales of the HD 7850 going AMD will prohibit manufacturers from offering factory overclocked Radeon HD 7790 cards, which might become faster than the Radeon HD 7850. Finally the HD 7790 will be based on a GPU known as Bonaire XT.
The Radeon HD 7790 will debut in April 2013 and will be the first in the line of new Southern Islands 3D graphics cards.
