13-inch MacBook Pro

Overview

Apple took some big steps forward with the refreshed 13.3" MacBook Pro. The new model migrates from the dated Intel Core 2 Duo to Intel's newer Core i5 and i7 CPUs. These dual-core mobile CPUs have a 3-4 MB level 3 cache shared by both cores and, thanks to Turbo Boost architecture, should be significantly more powerful than the Core 2 Duo processors they replace despite a tiny change in rated CPU speed.

The hot new technology this time is Thunderbolt, a 10 Gbps data connection that uses the Mac's Mini DisplayPort. Thunderbolt is 12 times as fast as FireWire 800, over 20 times as fast as USB 2.0, and twice as fast as USB 3.0, which Apple may never adopt if Thunderbolt takes off. Thunderbolt can be used for video, hard drives, and networking, and adapters let you connect FireWire and USB devices.

Apple has improved AirPort performance by building three WiFi antennas into the Early 2011 MacBook Pros, allowing three channels with 150 Mbps bandwidth for a maxmimum bandwidth of 450 Mbps.

The 13" MacBook Pro also takes some steps backward: The Nvidia GeForce 320M graphics give way to integrated Intel HD 3000 graphics, which uses 384 MB of system memory (up from 256 MB in last year's model).

The new models are rated at only 7 hours of battery power, down from 10 for last year's models, due to changes in the way Apple measures battery life. In testing, the Early 2011 models generally match or outperform the 2010 models.

The glass trackpad is the same one found in the previous generation of MacBook Pro models. It supports 1-, 2-, 3-, and 4-finger gestures. The entire trackpad functions as the mouse button.

The 13" MBP uses the same keyboard as before, complete with backlighting. The black keys look sharp with the aluminum enclosure, and the 13" MacBook Pro only comes with a glossy screen.

The new model comes in 2.3 GHz i5 and 2.7 GHz i7 versions. 320 and 500 GB hard drives are standard. 4 GB of RAM is standard, and it can be upgraded to 16 GB. 128, 256, and 512 GB SSDs are extra cost options.

Editor's note: The next two paragraphs are from the profile of the previous version of the MacBook Pro. At this time we do not know if they apply to the new Unibody model.

Note that the built-in display is only capable of 18-bit color, not the full 24-bit color you might expect.

Unlike early MacBooks, where every USB port could provide 500 mA of power, only one USB port provides full power - the port closer to the front.

The Apple Remote is a US$20 option.

Closed Lid Mode: All Intel 'Books support "lid closed" (or clamshell) mode, which leaves the built-in display off and dedicates all video RAM to an external display. To used closed lid mode, your 'Book must be plugged into the AC adapter and connected to an external display and a USB or Bluetooth mouse and keyboard (you might also want to consider external speakers). Power up your 'Book until the desktop appears on the external display and then close the lid. Your 'Book will go to sleep, but you can wake it by moving the mouse or using the keyboard. The built-in display will remain off, and the external monitor will become your only display. Since all video RAM is now dedicated to the external monitor, you may have more colors available at higher resolutions. The TiBook is designed to run safely in closed lid mode, but if yours runs hot (perhaps due to overclocking or high ambient temperatures), you may want to open the lid when in closed lid mode: The screen will remain off and the computer will more readily vent heat from the CPU.

To resume use of the internal display, you need to disconnect the external display, put the computer to sleep, and then open the lid. This will wake up your 'Book and restore use of the built-in display.

Intel-based Macs use a partitioning scheme known as GPT. Only Macintel models can boot from GPT hard drives. Both PowerPC and Intel Macs can boot from APM (Apple's old partitioning scheme) hard drives, which is the format you must use to create a universal boot drive in Leopard. Power PC Macs running any version of the Mac OS prior to 10.4.2 cannot mount GPT volumes. PowerPC Macs won't let you install OS X to a USB drive or choose it as your startup volume, although there is a work around for that.

Battery life is claimed to be 7 hours of wireless productivity.
