Processor
Choose the processor that best meets your performance needs. Your MacBook Pro comes as standard with the 2.5GHz dual-core Intel Core i5 processor. For even faster performance, configure your MacBook Pro with the 2.9GHz dual-core Intel Core i7 processor.
Your MacBook Pro features a dual-core Intel Core i5 or i7 processor based on 22-nanometer process technology with an advanced Core microarchitecture that features an integrated memory controller and Level 3 cache, giving the MacBook Pro faster, more direct access to memory. In addition, these processors feature:
Turbo Boost 2.0 - a dynamic performance technology that automatically boosts the processor clock speed based on workload, giving you extra processing power when you need it.
Hyper-Threading - a technology that allows two threads to run simultaneously on each core. So a quad-core MacBook Pro has eight virtual cores, all of which are recognized by OS X. This enables the processor to deliver faster performance by spreading tasks more evenly across a greater number of cores.
You can upgrade the processor in your MacBook Pro to the 2.9GHz dual-core Intel Core i7 processor with 4MB L3 cache and Turbo Boost speeds up to 3.6GHz.
