Apple’s 17-inch MacBook Pro is the Rolls-Royce of the MacBook Pro range. For many users it’s overkill. Not everyone needs the power and versatility it offers, and at a hundred pounds shy of two grand (possibly more, if you choose customisation options on the Apple online store), it certainly isn’t within everyone’s price range.
Yet for high-end users such as video editors and graphic designers, who need the extra screen space and processing power, this top-of-the-range 17-inch MacBook Pro 2.53GHz Intel Core i5 could well prove worth the asking price of £1,899.
The mid-2010 refresh brings a series of exciting new technologies. Automatic Graphics Switching means you no longer have to open your System Preferences to switch between integrated graphics for better battery life or the discrete chip, which is more powerful but heavier on the battery.
The new Core i5 processor introduces Hyper Threading, which gives the chip four virtual cores. Turbo Boost shuts down idle cores and increases the power to active cores, and an integrated memory controller speeds data processing. Physically, it’s identical to the previous model of 17-inch MacBook Pro, retaining its unibody construction.
The 15- and 17-inch MacBook Pros introduced with the mid-2010 refresh include a new feature called Automatic Graphics Switching. For routine tasks such as surfing the internet, checking email or using office applications, graphics processing is handled by the Core i5 processor’s built-in Intel HD Graphics, which lacks power but saves battery life.
When more graphical power is needed, such as when editing video or running advanced 3D games, graphics processing switches to the 17-inch MacBook Pro’s discrete GPU, an Nvidia GeForce GT 330M. This offers more power and greater energy efficiency than the GeForce 9600M GT used before. In the previous release of the 17-inch MacBook Pro, switching between the integrated and discrete graphics processor was a manual task achieved through System Preferences.
Not so now. Instead, graphics processing automatically switches to the discrete chip when a running application triggers an advanced graphics framework such as Core Graphics, OpenGL or Quartz Composer. No user intervention is required. When the discrete processor is active the integrated chipset shuts down, again saving energy.
If you wish to use the discrete GPU exclusively, you can switch off the 17-inch MacBook Pro’s Automatic Graphics Feature in System Preferences, forcing the notebook to use the more powerful chip at all times. Somewhat puzzlingly, there’s no option to restrict it to using integrated graphics, which could be useful if your battery was almost drained and you were prepared to sacrifice performance for extended use. Perhaps this feature will be introduced with the next system upgrade.

Thankfully, greater energy efficiency gives the 17-inch MacBook Pro a battery life of eight to nine hours, so the problem shouldn’t arise often. Like all modern MacBook Pros, the battery is housed inside the unit and is not user-serviceable.
But as the space saved by dropping the connectors and hatches required by a removable one has allowed Apple to incorporate a bigger, better battery. It’s expected to last around 1,000 charges or about five years, which is three times as long as a standard battery, making it more cost effective as well as more powerful.
features
The new Intel Core i5 2.53GHz processor brings a couple of new features not present in the Core 2 Duo chips used in the previous 17-inch MacBook Pro.
Hyper Threading allows two threads to run simultaneously on each of the processor’s two cores, giving a total of four virtual cores. This allows tasks to be spread more evenly for faster performance. And if your application doesn’t use all available cores, the processor’s Turbo Boost technology shuts down those that are unused and transfers the power to active cores.
The 2.53GHz processor used here can run at up to 3.06GHz when only one core is used. The new architecture also includes an integrated memory controller, connecting system memory directly to the processor and eliminating the need for a separate I/O controller, for faster data access and an improved operating speed.
It’s been claimed that the 2.66GHz Core i7 version of the 17-inch MacBook Pro (available as a custom option on the Apple online store) runs insanely hot when the processor is maxed out, reaching temperatures of over 100°C. Not so here.
Using a distributed computing application to take processor use up to almost 100% and iStat Pro to measure the CPU temperature, we found it barely rose above 80°C. This is still pretty hot, but it wasn’t causing problems for running applications. Impressively, the MacBook Pro ran silently, even after 15 minutes of running the processor at maximum.

Outwardly, the 17-inch MacBook Pro remains the same. It’s still built around a sturdy unibody design milled from a single piece of aluminium, it still has a backlit keyboard that illuminates as the light dims and it remains the only machine in the MacBook Pro range to retain the ExpressCard slot, which was dropped in favour of an SD Card reader in the 13-inch and 15-inch MacBook Pro models. On the downside, there’s still no Blu-Ray drive.
The mid-2010 refresh represents a very significant upgrade for the 17-inch MacBook Pro. Although its form factor is identical to the previous generation, the switch to the new Core i5 chip brings new technologies that greatly improve its performance. As a result, this 2.53GHz Core i5 chip is substantially faster and more powerful than the 2.8GHz Core 2 Duo used in the last generation of 17-inch MacBook Pros, a fact that was borne out in our benchmarking tests. The new graphics processor is also a significant step up.
We liked
Automatic Graphics Switching is a splendid feature that greatly improves on the manual switching method used before.
CPU features such as Hyper Threading and Turbo Boost get the most out of the Intel Core i5 processor, and attention has been paid to energy efficiency throughout. As a result, the internal battery lasts for eight or nine hours of normal use, up from seven hours in the previous release. That’s a whole day on your laptop on a single charge!
The unibody design, by which the 17-inch MacBook Pro is milled from a solid block of aluminium, means it’s surprisingly light and portable for a 17-inch notebook.
We disliked
There isn’t much to dislike here. Obviously, the 17-inch MacBook Pro is expensive, but you’re getting a lot for your money. One thing you’re not getting is a Blu-Ray drive, which is a shame. It really is time for Apple’s optical drives to take a step up.
You can’t restrict the MacBook Pro to using integrated graphics to save on power either, but this may come with a future system update.
Verdict
The new 17-inch MacBook Pro is expensive, but as it’s only £10 more than the previous model, it’s still good value for money. Welcome new processor and graphics technologies make this release a very significant upgrade.
