MacBook features sixth-generation Intel Core m3, m5, and m7 processors with speeds of up to 1.3GHz and up to 25 percent faster graphics. It also comes with faster 1866MHz memory. So your MacBook is quicker and more responsive.
MacBook has been engineered from the ground up for silent, efficient performance. It includes sixth-generation Intel Core M processors that run on just 5 watts of power, made even more efficient by optimizations throughout OS X. Together the processor and OS X sip so little energy that the system generates very little heat, so no fan is required to cool the computer.
3 million pixels. 0.88 millimeter. Razor sharp.
The 12-inch Retina display on the new MacBook isn’t just picture perfect — it’s also paper thin. In fact, at just 0.88 millimeter, it’s the thinnest Retina display ever on a Mac. A specially developed automated manufacturing process forms the impossibly thin edge-to-edge glass that’s only 0.5 millimeter thick.
Optimized for energy efficiency.
Each aspect of your MacBook — from the Retina display to the terraced battery to the advanced technologies of OS X — has been optimized to be as energy efficient as possible, with a typical energy consumption of 10.10 kWh per year. It also exceeds the low power requirements set by the EPA, giving it ENERGY STAR 6.1 qualification.
