Apple updates MacBook, MacBook Pro with 45nm processors

Intel’s new Penryn mobile processors have arrived in Cupertino. As AppleInsider reveals, Apple has refreshed its MacBook and MacBook Pro notebooks with the new chips, which are based on 45nm process technology and feature higher clock speeds, greater cache densities, and architectural improvements over their 65nm predecessors.

In Apple’s affordable MacBook line, 2.1GHz and 2.4GHz mobile 45nm Core 2 Duos have replaced the 2.0GHz and 2.2GHz 65nm chips Apple previously offered. The Mac maker has also taken the opportunity to bump the memory capacity of the two priciest MacBooks from 1GB to 2GB and dole out hard drive upgrades for all three machines. The $1099 MacBook now has 120GB of storage instead of 80GB, the $1299 model has been upgraded from 120GB to 160GB, and the $1499 variant is up from 160GB to 250GB.

Moving on to the pricier MacBook Pro range, Apple has replaced 2.2-2.4GHz 65nm Core 2 Duos with 2.4-2.5GHz 45nm models. Hard drive capacities have gone up, as well, from 120GB in the cheaper model and 160GB in the other two to 200GB and 250GB, respectively. In addition, Apple has bumped the onboard memory in the systems’ GeForce 8600M GT graphics processors. The base system that had the 128MB 8600M GT now has a 256MB part, and the other two now have 512MB GPUs.

Aside from hardware changes, AppleInsider reports that the MacBook Pro’s trackpad now supports the same multi-touch gestures Apple introduced on the MacBook Air. That means folks can now use some of the swiping, rotating, and pinching motions popularized by the iPhone to control apps like iPhoto.

The new MacBooks and MacBook Pros are available right now from the Apple Store.
