Apple has quietly upgraded its entire MacBook Pro lineup with faster processors and better internal storage without changing prices. The upgrades come just in time to capitalize on the holiday buying season.

The entry-level 13-inch MacBookPro comes in two versions, a $1,199 version that comes with a 2.4 Intel Core i5 processor, 500 Gb of storage space and 4Gb of RAM. The early 2011 versions that are being sold in stores right now only have a 2.3Ghz dual-core Intel Core i5, 4Gb of RAM, and 320 Gb of hard drive.

The faster 13-inch MacBook Pro will still sell for $1,499 but instead will come with a newer 2.8Ghz dual core i7 processor up from the early 2011 version with 2.7 Ghz processor. It will also have a bigger hard drive capacity of 750Gb up from its previous 500Gb version.

The Apple MacBook Pro 15-inch also has two versions available. The $1,799 version will have an increase in speed in its quad-core Intel Core i7 processor from 2.0 Ghz to 2.2 Ghz. The faster $2,199 version will have a speed bump on its processor from 2.2Ghz to 2.5 Ghz. Both models will also have better graphics card from AMD. The $1,799 model will get an AMD Radeon HD 6750M with 512Mb of graphics memory. The $2,199 model will get a Radeon HD 6770M.

The high-end 17-inch MacBook Pro line also received an upgrade with a faster processor, 2.4Ghz from the previous 2.2Ghz version. It will also receive an upgraded graphics card, an AMD Radeon HD 6770M with 1Gb of memory. The 17-inch MacBook Pro will still have the same price, $2,499 despite the upgrades.

The upgraded MacBook Pro line is listed as being in stock on the Apple store but check your local Apple stores for updates. While the upgrades aren't flashy it is still a significant bump in performance and at no extra cost. Buyers who are thinking of purchasing a MacBook Pro should opt to go for these newer models instead. Buyers who already bought their MacBook Pro earlier in the year shouldn't feel so bad, there's always next year.
