MacBook Pro upgrades announced by Apple

Apple has announced a range of upgrades to its MacBook Pro laptop line.

The platform holder has introduced advances in speed, storage, and graphics power for its 13-inch, 15-inch, and 17-inch models.

MacBook Pro's 13-inch entry-level model now comes with a 2.4GHz processor and an increased hard drive capacity of 500GB. The machine previously sported a 2.3GHz chip and 320GB of disk space.

The $1,499 (£936) 13-inch MacBook Pro has been given a 2.8GHz processor, up from 2.7GHz. Its hard drive has been upgraded to 750 gigabytes from 500GB. Both models have 4GB of RAM and come with the Intel HD Graphics 3000 card pre-loaded.

Apple's i7 processor has been introduced to the higher cost iteration, while the standard 13-inch laptop is still powered by an Intel Core i5 CPU.

Packing a new AMD Radeon HD 6750M graphic card with 512MB of RAM, the 15-inch model's i7 processor has been upgraded to 2.2GHz, from 2Ghz. Its hard drive capacity remains at 500GB. The mid-range model is priced at $1,799 (£1,124).
