The Apple MacBook "Core 2 Duo" 2.4 13-Inch (White - Early 2008/Penryn) features a 45 nm "Penryn" 2.4 GHz Intel "Core 2 Duo" processor (T8300), with two independent processor "cores" on a single silicon chip. It is equipped with a 3 MB shared "on chip" level 2 cache, an 800 MHz frontside bus, and 2 GB of 667 MHz DDR2 SDRAM (PC2-5300) installed in pairs (two 1 GB modules). Storage is provided by a 160.0 GB Serial ATA (5400 RPM) hard drive with "Sudden Motion Sensor" technology, and an 8X dual-layer write DVD±RW/CD-RW SuperDrive. The system's graphics are handled by an integrated Intel GMA X3100 processor that shares 144 MB of DDR2 SDRAM with main memory, driving a 13.3" widescreen TFT active-matrix "glossy" display (1280x800 native resolution).
The MacBook "Early 2008 Core 2 Duo/Penryn" series maintains the easily upgradable case design of its predecessors. Connectivity is also consistent, including AirPort Extreme (802.11a/b/g/n), Bluetooth 2.0+EDR, Gigabit Ethernet, a FireWire "400" port, two USB 2.0 ports, optical digital audio in/out, and mini-DVI for external display support.
These "Early 2008 Core 2 Duo/Penryn" models also include the "scrolling TrackPad", a built-in iSight video camera, the "MagSafe" power connector, a "flush against the bed" keyboard that avoids screen contact, and a "no moving parts" magnetic latch. Like its immediate predecessors in the "Late 2007" MacBook series, the keyboard lacks an integrated "numeric keypad", but unlike previous MacBook systems, the Apple Remote was a US$19 option rather than standard.
When compared to the models they replaced, the "Early 2008 Core 2 Duo/Penryn" models are powered by modestly faster and more energy-efficient 45 nm "Penryn" processors -- as opposed to the 65 nm "Merom" processors in the "Late 2007" series -- albeit with smaller 3 MB level 2 caches (compared to 4 MB). The "Early 2008 Core 2 Duo/Penryn" models also shipped with larger hard drives and twice the default RAM (in the 2.4 GHz models).
