- Each MacBook and MacBook Air uses a dual-core processor from Intel Corp.'s Core 2 Duo division, with a data transfer speed of 1,066Mhz. The CPU on the MacBook, the P8600, has a processing speed of 2.4GHz. The processors available for the MacBook Air are slower, with the SU9400 on the model with an 11.6-inch screen, and the SL9400 on the 13.3-inch version, offering processing speeds of 1.4GHz and 1.86GHz, respectively.
- The Nvidia GeForce 320M graphics processor on the MacBook and the MacBook Air takes up to 256MB of the computer's system memory, which it uses for video capability. The system memory itself offers up to 2GB, and it has an access speed of 1,066 MHz. Operating temperature is measured at 50 degrees to 95 degrees Fahrenheit, or 10 degrees to 35 degrees Celsius.
- For wired networking, the MacBook and the MacBook Air use an Ethernet driver, which provides up to 1,000 megabits -- or one gigabit -- per second in data transmission speed. Wireless networking comes from an AirPort Extreme Wi-Fi card that is compatible with the Institute of Electrical and Electronics Engineers 802.11a/b/g/n standards, as well as Bluetooth 2.1 + Enhanced Data Rate technology. The computers' two USB 2.0 ports provide a peak data transmission rate of 480 Mbps.
- The MacBook uses a built-in 63.5-watt-hour lithium-polymer and 60-watt MagSafe power adapter for power. The MacBook Air requires lesser power requirements -- with a 35-Whr battery for the 11.6-inch model, a 50-Whr battery for the 13.3-inch and a 45-W power adapter for both screen sizes. The battery on the MacBook, which is only available with a 13.3-inch screen, and the 13.3-inch MacBook Air provides up to seven hours of operation based on wireless Web browsing. The 11.6-inch laptop offers two hours less operating time.
