After a successful launch of the Radeon HD 5000 series DirectX 11 compliant graphics processors, a lineup was created which spans from the very high-end dual-GPU Radeon HD 5970 at its >$500 price point, Radeon HD 5800 series as its performance segment, Radeon HD 5700 as its upper mainstream, HD 5600 as mainstream, and then on the entry-level Radeon HD 5400 and HD 5500 series. There was, however, a scope for expanding the performance segment a little, on both its ends. Until today, the Radeon HD 5850 and Radeon HD 5870 1GB are the only two members of this sub-series, targeting roughly-$300 and roughly-$400 price points, respectively. The next GPU lower down the food chain is the Radeon HD 5770. At its price and offer, it impressed us to the fullest, but there's a void created between this roughly-$160 GPU and the Radeon HD 5850, which is almost twice its price. This is the void that AMD is planning to fill with their latest product release.Enter the Radeon HD 5830. This GPU is situated in a price-stratum that's between the Radeon HD 5770 and Radeon HD 5850, and, at face value, promises performance and features worth its price, if not more. In this review, we set out to investigate just that: whether AMD managed to fill that void.
