I would presume that, if you have a low-budget application with high scale (e.g. you're a company designing a NAS, or other "Turing-complete but still embedded" system), then you'd ignore both Intel and AMD and look at ARM-based SoC solutions, no? You can get significantly better integrated graphics, for cheaper, on e.g. Nvidia's Tegra platform. Thus why Nintendo—ROI penny-pinchers to a fault—chose it.
