AMD currently has three cards in the Radeon HD 4800 family; Radeon HD 4870X2, 4870 and 4850. They have all been well received and surprised even NVIDIA with the kind of performance they delivered. Through aggressive pricing AMD has been able to reclaim much of the honor lost with the previous generation, but there seems to be more coming. Radeon HD 4830 is a slightly stripped version, but unlike the Radeon HD 3830, it has not been stripped of memory bandwidth.
By the looks of it, Radeon HD 4830 will still have the “full” 256-bit bus, but instead sport only 640 shaders and 32 texture units. The memory will be GDDR3, which means that it will be somewhat starved of bandwidth just like the 4850 model. It will only need one PCIe power connector and according to AMD’s own testing it is up to 60% faster than Radeon HD 3850, and outperforms GeForce 9800GT across the board.
The price? Below $150 to fill the space between Radeon HD 4850 and 4670.
