Two years ago Ubuntu began supporting LPIA, or the Low-Power Intel Architecture. LPIA is i386, but with different compile-time optimizations. LPIA was in use by the Ubuntu Mobile project with Intel's recent mobile CPUs supporting this lower-power architecture. Tests we carried out earlier this year at Phoronix showed Ubuntu's LPIA-based MID spin can conserve 10%+ power. However, Canonical is now abandoning this Intel architecture.
