MacBook Pro elevates the notebook to a whole new level of performance and portability. Wherever your ideas take you, you’ll get there faster than ever with cutting-edge graphics, high-performance processors, whip-smart storage, and more. With seventh-generation Intel Core processors, MacBook Pro delivers amazing performance so you can move fast — even when powering through pro-level processing jobs like rendering 3D models and encoding video. At the same time, it can conserve energy when taking on lighter tasks, like browsing the web and checking email. And 10-bit HEVC hardware acceleration comes standard on MacBook Pro, which will let you take even more advantage of the boosts in 4K video compression and streaming performance coming in macOS High Sierra.
The Apple MacBook Air "Core i5" 1.6 11-Inch (Early 2015/Broadwell) features a 14-nm "Broadwell ULT" 1.6 GHz Intel "Core i5" processor (5250U) with two independent processor "cores" on a single chip, a 3 MB shared level 3 cache, 4 GB of onboard 1600 MHz LPDDR3 SDRAM (which could be upgraded to 8 GB at the time of purchase, but cannot be upgraded later), 128 GB or 256 GB of PCIe-based flash storage, and an "integrated" Intel HD Graphics 6000 graphics processor that shares system memory.
