 Tuesday updated its MacBook Pro line of notebook computers with faster processors and new Nvidia graphics.

The biggest news amid the new MacBook Pro changes is that the 15-inch and 17-inch models now use Intel's Core i5 and i7 processors. The 13-inch model will continue to use Intel's Core 2 Duo processor.

The 15-inch and 17-inch models will also use Apple's graphics switching technology, which allows the computer to automatically toggle between the Nvidia GeForce GT 330M and Intel's HD Graphics processors.

The 13-inch MacBook Pro comes with 4GB memory and Nvidia's GeForce 320M graphics processor. There are two configurations, one with a 2.4GHz processor and 250GB hard drive for $1,199, and the other with a 2.66GHz processor and a 320GB hard drive for $1,499.

The 15-inch MacBook Pro is available in three models: a 2.4GHz Intel Core i5 with the Nvidia GeForce GT 330M and 320GB hard drive for $1,799; a 2.53GHz Intel Core i5 with the Nvidia GeForce GT 330M and 500GB hard drive for $1,999; and one with a 2.66GHz Intel Core i7, Nvidia GeForce GT 330M, and 500GB hard drive at $2,199.

The new 17-inch MacBook Pro features a 2.53 GHz Intel Core i5, Nvidia GeForce GT 330M, and 500GB hard drive for $2,299.

The multitouch trackpad on the new MacBook Pro's multitouch trackpad also support inertial scrolling, a feature that Apple says is better for scrolling through large photo libraries, lengthy documents and long web sites.

Compared to older models 
Apple's previous-generation MacBook Pros also came in three models: 13-, 15-, and 17-inch.

The earlier 13-inch MacBook Pro came in two models. The low-end configuration had a 2.26GHz Intel Core 2 Duo processor with 2GB memory, a 160GB had drive, an SD card slot, and Nvidia GeForce 9400M graphics. The high-end 13-inch model had 2.53GHz Intel Core 2 Duo, 4GB memory, a 250GB hard drive, and the same graphics and SD slot as the low-end model.

The earlier 15-inch MacBook Pro was available in three models. The low-end model was powered by an 2.53GHz Intel Core 2 Duo processor, 4GB memory, a 250GB hard drive, an SD slot, and the Nvidia GeForce 9400M graphics. The midrange notebook had a faster 2.66GHz processor with 4GB memory, 320GB hard drive, an SD slot, and Nvidia's GeForce 9400M + 9600M GT with 256MB memory. The high-end model was the same as the midrange 15-inch MacBook Pro, except it came with 2.8GHz processor and a 500GB hard drive.

The largest of Apple's notebook offerings was the 17-inch model. Before Tuesday's update, it had a 2.8GHz processor, 4GB memory, a 500GB hard drive, an ExpressCard/34 slot and Nvidia's GeForce 9400M + 9600M GT with 512MB.
