Nordic Hardware has a report stating that AMD will be launching a new mid-range graphics part called the Radeon HD 6790, which is supposed to be an answer to Nvidia's just announced GeForce GTX 550 Ti.
The Radeon HD 6790 will be more powerful than a Radeon HD 5770, at a lower price than Radeon HD 6850. According to the report, the 6790 will use a GPU called the Barts LE, which uses AMD's classic VLIW5 architecture with 10 SM units with 800 stream processors. In comparison, the 6850's Barts Pro GPU has 12 SM units and 960 stream processors.
The clock speed is said to be at 840MHz and the memory at 1050MHz (4200MHz effective), all on a 256-bit interface.
ND said that this new card was supposed to launch on March 31, but instead is now launching on April 5.
