The thermal architecture in MacBook Pro has been completely redesigned, featuring larger impellers with improved fan blades for optimal airflow and more heat-dispersing fins for more effective cooling. The resulting gain in cooling capacity allows MacBook Pro to deliver up to 12 watts more maximum sustained power.
MacBook Pro has a big voice. The six-speaker sound system produces room-filling wide stereo sound like you’ve never heard from a notebook before. Dual force-canceling woofers dramatically reduce system vibration for a clearer, more natural sound and a half-octave lower range to the bass. And the studio-quality three-mic array rivals professional third-party microphones, for creating superclean podcasts or music recordings on the go.
