The MacBook Pro "Core 2 Duo" 2.26 13" (SD/Firewire 800 - Mid-2009) features a 45 nm "Penryn" 2.26 GHz Intel "Core 2 Duo" processor (P7550 or P8400), with two independent processor "cores" on a single silicon chip, a 3 MB shared "on chip" level 2 cache, a 1066 MHz frontside bus, 4GB installed in pairs, a 320 GB  hard drive, an 8X DL "SuperDrive", a NVIDIA GeForce 9400M "graphics processor with 256 MB of DDR3 SDRAM shared with main memory", integrated iSight, and an LED-backlit 13.3" widescreen TFT active-matrix "glossy" display (1280x800 native resolution).

Connectivity includes AirPort Extreme (802.11a/b/g/n), Bluetooth 2.1+EDR, Gigabit Ethernet, a Firewire "800" port, two USB 2.0 ports, the same "combined optical digital output/headphone out (user-selectable analog audio line in)" port used by the iPhone, a "Mini DisplayPort" that supports an external display at 2560x1600, and an SD card slot.

Although this model is packed in essentially the same "Unibody" case design -- one milled from a single block of aluminum -- as the 13-Inch "non-Pro" MacBook that it replaced, and it has the same backlit keyboard and "no button" glass "multi-touch" trackpad with support for "four finger" gestures and programmable "zones", and a very similar internal architecture, there are notable differences as well. The "Mid-2009" 13-Inch MacBook Pro models support more RAM, have an improved display (said to have "60% greater color gamut"), and have a non-swappable battery design. They also add the aforementioned SD card slot and a Firewire "800" port, but drop the previously standard optical digital audio input capabilities.
