AMD Radeon HD 6000 Benchmarks Leaked
AMD's latest Radeon HD 6000 series graphics cards are slated to launch this month. The first two cards are widely expected to use the new Barts GPU but the confusing thing is that this isn't their high-end part. Instead, they are widely believed to be "mainstream" options and if benchmarks are to be believed, will perform somewhere around the Radeon HD 5850 mark.
