AMD’s highly successful HD 3800 series of GPUs is about to get a new member, the HD 3830.  Since the card hasn’t shipped yet, all the details are subject to change.  Now on to the details:“AMD’s Radeon HD 3830 will be based on the RV670 core and will feature a 128-bit memory bus, potentially providing roughly half the memory bandwidth of the HD 3850 and 3870 depending on the type and speed of memory used. All other features of the 55nm RV670 core are still included: DirectX 10.1, PCIe 2.0 and UVD.
