AMD provides details on the Bonnaire XT based HD 7790.
As was rumoured last month, AMD will be releasing the entry-level Radeon HD 7790 graphics card to bridge the gap between the HD 7770 and HD 7850. The HD 7790 will feature 786 shader processors instead of the previously indicated 896, a clock rate of 1075 MHz and 2 GB of GDDR5 memory over a 128-bit interface and support DirectX 11.1 and OpenGL 4.3. According to a now redacted result posted on CL benchmark's website, the HD 7790 can be expected to provide 10 percent lower performance than a HD 7850.
Interestingly, the HD 7790 is actually based on the 28 nm Bonnaire XT chip and uses the GCN 2.0 architecture that will also be used in the upcoming Radeon HD 8000 series. For an explanation of AMD's somewhat confusing naming conventions, refer to both our coverage of the HD 8000 series delay and the overview of AMD's plans for 2013.
The Radeon HD 7790 has a recommended price of £118 and will be available in April 2013.
