Intel’s fifth-generation dual-core processors house the processor, L3 cache, Intel Iris Graphics 6100, and fast 1866MHz memory controller on a single chip. These processors feature Turbo Boost technology that automatically boosts the processor clock speed based on workload, giving you extra processing power when you need it. And Hyper-Threading technology allows two threads to run simultaneously on each core. This enables the processor to deliver faster performance by spreading tasks more evenly across a greater number of cores.
The more memory your computer has, the more apps you can run simultaneously and the better performance you get from your computer. MacBook Pro with Retina display uses one of the fastest memory technologies available today — 1866MHz Low-Power Double Data Rate 3 (LPDDR3), synchronous dynamic random-access memory (SDRAM) — ensuring that the Intel Core i5 and i7 processors are constantly fed with data without wasting clock cycles. Compressed Memory in OS X allows your Mac to free up memory space when you need it most. As your MacBook Pro approaches maximum memory capacity, OS X automatically compresses data from inactive apps, making more memory available.
Note that MacBook Pro with Retina display comes with 8GB of memory built into the computer. If you think you may need more memory in the future, it is important to upgrade at the time of purchase, because memory cannot be upgraded later in this model.
Your MacBook Pro can be configured with the keyboard language options listed. The User’s Guide language will match that of the keyboard language chosen unless otherwise specified. Mac OS X is a multilingual operating system. During the setup process you can choose one of the many languages it supports for application menus and dialogs and to read and write text. Mac OS X also allows you to select your preferred language at any time using System Preferences.
Note: Your computer comes equipped with cables appropriate for the country in which you purchased it.
