Facing increasing competitive pressure, Apple silently pushed performance enhancements to the MacBook Pro line of laptops. The changes include better processors and additional storage, and on higher-end models better graphics cards.

The base level 13-inch MacBook Pro now sports a 2.4GHz Intel Core i5 dual-core processor with a 500GB hard drive, but remains at $1,199. The faster $1,499 13-inch model now includes a 2.8GHz i7 dual-core CPU with a 750GB HDD.

Apple's previous 13-inch models -- launched in February -- included a 2.3GHz i5 processor with 320GB hard drive, and 2.7GHz i7 processor with 500GB of storage space respectively.

Both 15-inch models got faster processors and upgraded graphics cards. On the $1,799 model, the 2.2GHz quad-core i7 CPU replaces the 2GHz chip, and the AMD Radeon HD 6490M graphics card has been swapped out with the 6750M. The higher-end $2,199 version goes from 2.2GHz to 2.4GHz, and now sports the AMD Radeon HD 6770M as opposed to the 6750M.
