The author mentions the new CPUs in a footnote: "Except new CPUs, but who cares? CPUs are the least exciting (and usually least relevant) upgrades in modern mass-market personal computers." For the vast majority of users, including many power users, moving from a "very fast" processor to an "extremely fast" processor is much less of a performance gain than moving from a HDD to a SDD.
