Apple laptops switch on Core 2 Duo chips

New MacBook Pro models touted as 39 per cent faster.

Apple has unveiled a new line of its MacBook Pro laptops that feature Intel's Core 2 Duo processors.

The notebook models are the first to use Intel processors that are based on Intel's power-efficient Core Microarchitecture. Apple claims that the new chips on average will function up to 39 per cent faster than the Core Duo chips in the previous MacBook Pro models.

The three new MacBook Pro models feature 2.16GHz and 2.33GHz processor speeds. The 2.16GHz model will be available with a 15-inch screen and the 2.33GHz model will offer either a 15- or 17-inch screen.

The new models will also offer larger 120Gb or 160Gb hard drives and Firewire 800 connectivity.

“With an Intel Core 2 Duo processor, greater storage capacity and FireWire 800 connectivity, the new MacBook Pro delivers unprecedented performance and mobility in an incredibly thin and light design,” said Apple’s senior vice president of worldwide product marketing Philip Schiller.

Originally launched by Intel in July, the Core 2 Duo chip bundles two processor cores on a single chip together with the new Core Microarchitecture.

The 15-inch models are selling for US$1,999 (2.16GHz model) and US$2.499 (2.33GHz model). The 17-inch model is slated for availabilty next week for US$2,799.
