ExtremeTech reviews the GPU on ATI's recently announced Radeon 9100 IGP motherboard. This new value targeted motherboard is a Pentium4 range board. According to ExtremeTech ATI is still 'tweaking the memory controller. The problem is that entry-level Pentium 4-based PC makers are hard-pressed to deliver decent 3D performance at a very low price-point. But it's also an opportunity for ATI; and one the company has responded to with its new Radeon 9100 IGP system chipset. ATI's latest integrated solution, which is targeted at both laptop and desktop systems, brings DX8-level technology into a north bridge, and with it respectable entry-level gaming performance. This DX8 level of performance means pixel shader hardware, and the in the case of the R9100 IGP, the ability to do vertex shaders in software.
