Quietly unveiled without a press release -- just like the model it replaced -- the Apple MacBook "Core 2 Duo" 2.13 13-Inch (White - Mid-2009) features a 45 nm "Penryn" 2.13 GHz Intel "Core 2 Duo" processor (P7450), with two independent processor "cores" on a single silicon chip, a 3 MB shared "on chip" level 2 cache, a 1066 MHz frontside bus, 2 GB of 800 MHz DDR2 SDRAM (PC2-6400) installed in pairs (two 1 GB modules), a 160 GB Serial ATA (5400 RPM) hard drive, an 8X DL "SuperDrive", a NVIDIA GeForce 9400M "graphics processor with 256 MB of SDRAM shared with main memory", and a 13.3" widescreen TFT active-matrix "glossy" display (1280x800 native resolution).
The MacBook "Core 2 Duo" 2.13 13" (White - Mid-2009) shares the same white polycarbonate case as the MacBook "Core 2 Duo" 2.0 13" (White - Early 2009) that it replaced and connectivity is the same as well with AirPort Extreme (802.11a/b/g/n), 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 hard drive is larger and the memory is faster. Interestingly, Apple also officially claims that this model provides 5 hours of battery life (up from 4.5 hours on the model replaced).
