Sapphire Radeon HD 6790 Review

Remember the Radeon HD 5830? That videocard filled a certain price point, but it was actually the same GPU used in the high-end HD 5870, with a large chunk of the die disabled. Enter the Radeon HD 6790. At first blush, it’s similar in concept to the HD 5830. AMD took its Barts GPU (used in the Radeon HD 6870 and 6850) and disabled a big chunk of it. Voilà: the Radeon HD 6790.
