They are still, in comparison to mobile phone SoCs, incremental increases in power. Especially the Core-i series of the last few years. On top of that they still sell computers with dual-core celeron and pentium processors because they're "good enough" and instruction sets haven't changed much. Smartphone SoCs have seen leaps and bounds both in the physical silicon and in stuff like instruction set support, hw codecs and the like.
