This is because it costs money, and the 880G is pitched as a budget chipset. AMD says that it is possible to have dual digital outputs, and has been since 780G, yet motherboard makers never use it. This is something AMD has yet to embrace at the chipset level. The Radeon HD 4350 is the most modest card in ATI’s range. The ATI Radeon HD 4550 (RV710) graphics card pictured above measures in at just 6.625. Intel does edge ahead by offering dual digital outputs from its latest GMA HD IGP. The graphics card I will be taking a closer look at today is the Radeon HD 4550, so lets jump right into it. If we were feeling mean, we might point out that AMD has been using a 55nm process since 2008 (first seen on the 780G) but it's a technology that works and we'd rather AMD concentrate on shrinking its CPU and GPU dies than its chipsets. The chipset is still manufactured on TSMC's 55nm process, one step behind Intel, which is using a 45nm process for its GMA HD and chipsets. It still offers a basic 40 stream processors (in eight groups of five), with the chipset itself providing 22 PCI-E 2.0 lanes (four are used for the chipset to Southbridge interconnect) and the UVD 2.0 standard of the 785G.
The core engine is still based on RV620, which is a DirectX 10.1 GPU rather than a DX11 one. It's the same Radeon HD 4200-series GPU, except with a 60MHz clock bump and subsequent rebrand from HD 4200 to HD 4250. That's because, essentially, they are the same. If you click to view the table below in enlarged form, you'll notice there's not that much difference between the IGPs of the new 880G chipset and the old 785G. Radeon HD 4250 Game Requirement Analysis Radeon HD 4250 (IGP) is an integrated GPU on the AMD 880G Chipset. AMD's 880G northbridge on the left, and SB850 southbridge on the right.
