It’s a little sad and frustrating that some websites can’t respect embargo’s, however a Sweden based website SweClockers posted the first photo’s of a Sapphire Dual-X OC graphics card. Not only that, they ran and published a few benchmarks as well. The Radeon HD 7790 presumably is based on a 28nm Bonaire based GPU based on GCN 2.0 architecture.
The GPU has 768 stream processors with 1 or 2 GB running over a 128-bit GDDR5 memory bus. SweClockers reports that the card will get a 150 Watt TDP abd a 1075 MHz clock frequency with 6.4 Ghz on the memory. The Sapphire Dual-X OC comes with two fans, dual-DVI, HDMI and display port.
If all info is correct then this might be a nice little entry level graphics card alright.
