The Apple MacBook Core 2 Duo 2.1 13-Inch (White – Early 2008/Penryn) features a 45 nm Penryn 2.1 GHz Intel Core 2 Duo processor (T8300), with two independent processor cores on a single silicon chip, a 3 MB shared on chip level 2 cache, an 800 MHz frontside bus, 2 GB of 667 MHz DDR2 SDRAM (PC2-5300) installed in pairs (two 1 GB modules), a 160.0 GB Serial ATA (5400 RPM) hard drive with Sudden Motion Sensor technology, an 8X dual-layer write DVD±RW/CD-RW SuperDrive, an Intel GMA X3100 integrated graphics processor with 144 MB of DDR2 SDRAM shared with main memory, and a 13.3″ widescreen TFT active-matrix “glossy” display (1280×800 native resolution).
The MacBook Early 2008 Core 2 Duo/Penryn series shares the same easy to upgrade case design as previous MacBook systems, and connectivity likewise includes 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 video out capabilities (mini-DVI) that supports an external display.
The MacBook Early 2008 Core 2 Duo/Penryn models also include the scrolling Trackpad, built-in iSight video camera, MagSafe power connector, flush against the bed keyboard that does not touch the screen, and no moving parts magnetic latch that catches without a catch.
Compared to the models each replaced, the MacBook Early 2008 Core 2 Duo/Penryn models are powered by modestly faster and more energy-efficient 45 nm Penryn processors — compared to 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 additionally shipped equipped with larger hard drives and twice the default RAM (in the 2.4 GHz models).
