Apple Inc. announced new specs of its MacBook Pro laptops upgrading its mobile computing line with new processors and graphics chips along with longer battery life.

Since the last MacBook Pro models were released, changes have been common to laptop components. Most significant is the release of a new family of Intel processors, including the Core i3, Core i5, and Core i7 — all of which offer better performance and battery life than the standard Intel Core 2 Duo CPUs found in current MacBooks.


The 15 and 17-inch macBook Pros now offer Core i5 and Core i7 processors. The 13-inch MacBook Pro is keeping the older Core 2 Duo, but upping its default clock speed from 2.26GHz to 2.4GHz.


All models will now carry an advertised built-in battery that Apple estimates will have as much as 10 hours of usability before a charge, up from an estimated seven hours in the previous models.
