iMac performance evolves through the years

To commemorate the 10th anniversary of the iMac’s release, Macworld Lab digs some older machines out of storage to see how well they perform compared to the current models.

From the Lab: Comparing new iMacs to older models

When Apple releases new hardware, it’s usually not owners of the previous models that are looking to upgrade—rather, it’s people who own older systems. With that in mind, Macworld Lab compares the test results for the latest iMacs to some older models, including a Core Duo-based iMac and an iMac G5.

How Psystar’s computer measures up to a Mac

The Open Computer, an Intel-based machine capable of running OS X, can outperform a Mac mini. But it lagged behind the entry-level iMac as well as a home-built system in our benchmark testing.

From the Lab: Penryn iMacs show promise

Macworld Lab has begun testing the new iMacs released Monday, and we’ve got results for the entry-level 2.4GHz model as well as the build-to-order 3.06GHz machine.

From the Lab: Mac Pro options put to the test

The current Mac Pro may be the most customizable machine to ever come out of Cupertino. But what do each of those options add in terms of performance? Macworld Lab has configured a Mac Pro to test tweaks to memory, the hard drive, and the graphics card to figure out what effect each upgrade has on the Mac Pro’s speed.

From the Lab: Optimizing the MacBook Pro

We’ve seen what Intel’s next-generation of Penryn chips can do to the performance of both MacBook Pros and MacBooks. But that testing focused on standard configurations rather than build-to-order configurations. And now we’ve gotten our hands on such a system, a customized MacBook Pro, to see how optimizing the hardware translates to performance gains.

Review: MacBook Pro Core 2 Duo/2.4GHz and 2.5GHz

If you've been waiting to buy a new Apple laptop, or you've been hesitating about upgrading from your G4 PowerBook, wait no longer. While the 2.4GHz model is a fine value for the money, the higher-end 15-inch and 17-inch models are outstanding top-of-the-line models for any professional, artistic, scientific, or scholastic application.

From the Lab: MacBooks get a boost from Penryn

Like their high-end counterparts, the MacBook Pro, the MacBook also has seen its processor replaced with a next-generation version of the Core 2 Duo chip. And that’s meant performance gains for the MacBook when compared to the most recent version of the laptop as well as older Core 2 Duo-powered models. What’s more, the high-end 2.4GHz MacBook compares favorably to the 2.4GHz MacBook Pro.
