Following AMD's launch of the 890GX chipset which marked the entry of certain new features native to the chipset, the company is readying a slightly scaled-down version of it aimed at more mainstream consumers, business PC users, as well as HTPC and home PC users. The AMD 880G succeeds the 780G is being a mid-range integrated graphics chipset that supports a range of new features using the SB800 series southbridge chips.
While the 880G is based on essentially the same chip (RS880) as the 890GX, certain features such as ATI CrossFire are disabled, and board makers are directed to use this chipset on micro-ATX form-factor designs. The 880G northbridge packs an RV620-core based ATI Radeon HD 4250 IGP which supports DirectX 10.1, with 40 stream processors, and DDR3 SidePort memory support apart from the usual UMA. The IGP supports native HD video decode features, as well as HDMI with on-chip 7.1 channel audio. While the chipset supports one PCI-Express 2.0 x16 link for discrete graphics, it also gives out PCI-Express 2.0 x1, x4 lanes from the northbridge. Additional controllers such as USB 3.0 can benefit from a direct PCI-E 2.0 path. The SB800 class southbridge has a native 6 channel SATA 6 Gb/s controller complete with RAID support.
