Apple MacBook Pro 2.5GHz 15-inch full review
These new MacBook Pro models might be classified as speed bumps, implying that the pro laptops’ new enhancements constitute a minor, albeit noteworthy update.
However, the updated models actually represent a fairly significant upgrade – both in terms of technology and performance – over their predecessors, which were last updated in November. Debuting Intel’s 45 nanometer Penryn processor (a new generation of speedier chips that top the 65-nanometer Merom chips powering the earlier models), the new 2.5GHz MacBook Pros achieved the best scores of any laptop in Macworld’s Speedmark 5 benchmark tests.
Despite that accomplishment, some might be disappointed that there was no redesign of the case, and that Apple has made its Front Row remote control, formerly free, a £15 optional extra. The trackpad, which is the same size as in previous models, has been updated to accommodate the multi-touch hand gestures it introduced in the iPhone and featured on the MacBook Air. For example, pinching an image will reduce its size, while swiping will advance you to the next image.
MacBook Pros were designed with the multimedia artist in mind, which means it’s the laptop of choice for people who work with audio, video, or large images as well as high-end applications. The new MacBook Pro, as usual, comes in three configurations: a 15in 2.4GHz Intel Core 2 Duo model; a 15in 2.5GHz model; and a 17in 2.5GHz system. And they’re the same price: £1,299, £1,599 and £1,799 respectively – as the models in the previous line. You can also purchase a 2.6GHz Core 2 Duo chip as a build-to-order option for the 2.5GHz 15in or 17in model for an extra £160.
Inside and out
From the outside, the new 15in and 17in MacBook Pros are identical to their predecessors. All are 25mm thick. All come in the same 360mm and 390mm light grey aluminum cases. The 15in MacBook Pro weighs 2.45kg; the 17in model weighs 3.08kg.
Both 15in models come with LED backlit anti-glare screens with resolutions of 1,440 x 900 pixels. These wide screens immediately illuminate to full brightness and are mercury-free. Glossy displays are available as an option for all models. The 17in MacBook Pro, which ships with standard LCD backlighting technology, has a resolution of 1,680 x 1,050 pixels. Apple offers high-resolution LED backlit screens as an option for the 17in model. These larger LED backlit displays – which offer 1,920 x 1,200 pixels – are mercury-free, arsenic-free, and cost £60 extra. Macworld did not test the 17in LED model for this review.
The new MacBook Pros all ship with 2GB of installed RAM (upgradeable to 4GB) and an 8x SuperDrive. All models come with an NVIDIA GeForce 8600M GT graphics processor, though the entry-level 2.4GHz model features 256MB of video memory, while the other two configurations offer 512MB. Each model has twice the video RAM of its predecessor. The 15in models have two USB 2.0 ports while the 17in model has three.
The 2.4GHz system comes with a 200GB hard drive, up from 120GB in the previous analogous model. The two 2.5GHz MacBook Pros offer 250GB of storage, with a 300GB hard drive available as a £50 build-to-order option for the 17in laptop. That compares with the 160GB hard drive in the older 15in high-end and 17in models.
While we’re excited that the MacBook Pro’s new trackpad now supports multi-touch hand gestures, we’ve found that because the trackpad is the same size as the previous models, the button often gets in the way. That said, the button did not affect the performance of the gestures, which work with the following applications in addition to the Finder: iCal, Safari, Preview, QuickTime Player, DVD Player, iPhoto, Mail, Address Book, and Aperture 2.0.
One thing that has changed from the previous MacBook Pro is the row of function keys at the top of the keyboard. The location of the media, volume, and keyboard illumination keys has been changed, there are new keys to control Exposé and Dashboard, and the NumLock key (as well as the rest of the numeric keypad) is now gone. However, the keyboard is nice and springy and has a comfortable, non-spongy feel.
With the new Penryn chips comes a boost to the MacBook Pro’s shared L2 cache capacity to 6MB. The two 2.5GHz MacBook Pro models carry 6MB of L2 cache, up from 4MB in the previous models. Interestingly, the 15in 2.4GHz MacBook Pro has 3MB of L2 cache, a drop-off from its predecessor. Despite that, the low-end MacBook Pro often performed better than its older siblings in Macworld’s battery of benchmark tests. And, while its Speedmark score registered 10 per cent faster than last year’s low-end model, other comparisons were more dramatic: The new 2.4GHz model was 23 per cent faster than that older 2.2GHz system in our Photoshop test suite.
Even with less L2 cache, the new entry-level MacBook Pro finished just one point under last year’s build-to-order MacBook Pro, which featured a 2.6GHz Core 2 Duo chip. The new machine was about 8 per cent faster in Speedmark and 23 per cent faster in the Photoshop suite. Packed with double the video memory, the new 2.5GHz MacBook Pro topped the older build-to-order machine in our Unreal Tournament test by some 21 per cent.
If you were among the first to buy Apple’s Intel pro laptop a couple of years back, it’s interesting to note that the new 15in, 2.5GHz MacBook Pro scores reflect roughly a 50 per cent boost in both Speedmark 5 tests and our Compressor tests.
We also found the new model to be 36 per cent faster than the older 2GHz MacBook Pro in our Photoshop suite and 31 per cent faster in our Cinema 4D test. And the low-end 2.4GHz MacBook Pro had a Speedmark score more than twice as fast as the PowerBook G4.
Insofar as non-scientific hands-on experience goes, these new MacBook Pros felt energetic: while startup time was about 25 seconds, launching Photoshop CS3 took about eight seconds. Some of Apple’s built-in apps, such as Safari and iCal, launched instantaneously.
The 15in 2.5GHz MacBook Pro’s battery life improved significantly – about 21 per cent over the previous model, lasting 2 hours 55 minutes, compared with 2 hours 25 minutes for the 2.2GHz model. The battery boost for the new 17in model is a less-impressive 5 per cent: 2 hours 53 minutes for the 2.5GHz model as opposed to 2 hours 45 minutes for the previous 2.4GHz model.
