Power management on 14 nm Intel® Core− M processor
The desire to deliver breakthrough performance in a tablet form factor required several innovations in the 14nm Intel® flagship Core™ processor (Broadwell). Better frequency control algorithms including duty cycling graphics cores were developed to improve energy efficiency. New power sharing algorithms were developed to maximize performance of multiple compute domains within tight thermal and power delivery constraints. Innovations resulted in upto 50% increase in performance and upto 25% improvement in battery life over a Haswell system thermally constrained to a 4.5W fanless form factor.
