According to sources, AMD will launch on 5 April a new model of graphics card, the Radeon HD 6790. Based on a chipset Barts THE etched into 40 nm, with 800 stream processors and 40 texture units and clocked at 840 MHz, this card has 1 GB of GDDR5 memory running at 1050 MHz on a 256-bit bus, for a bandwidth up to 134.4 GB / s.
Two power connectors PCI-Express 6-pin would be required, while the peak at 150 watts TDP. Able to deliver a power of 1.34 TFLOPS, the Radeon HD 6790 seems slightly less powerful than the Radeon HD 6850 (1.5 TFLOPS) while consuming substantially more (the TDP of the Radeon HD 6850 is 129W).
We therefore expect that the Radeon HD 6790 is displayed at a lower rate than the 6850, probably in the neighborhood of $ 150. Come on, a few more days to wait ...
