EDIT to expand a bit since some people seem to be missing the point: hypothetically, GP might have preferred Intel on narrow technical criteria, but have been willing to override that preference for the sake of transparency. No transparency difference, no reason to override.
Fwiw I'm not ready to use open-ish ARM/POWER exclusively, but AMD/Intel'll have to contend with that soon(tm)
[Answer to parents EDIT] I'd argue the effective technical difference set between AMD & Intel is growing ever narrower, and aside from brand fidelity there is very little reason for a consumer to have non-moral preferences to one or the other manufacturer.
