The MacBook Pro "Core i7" 2.66 15-inch (SD - Mid-2009) is equipped with a 45 nm "Penryn" 2.66 GHz Intel "Core 2 Duo" processor (P8800). It has two independent cores on a single silicon chip, a 3 MB shared level 2 cache, a 1066 MHz frontside bus, and 4 GB of 1066 MHz DDR3 SDRAM (PC3-8500) installed in pairs. The system includes a 320 GB Serial ATA (5400 RPM) hard drive, an 8X DL "SuperDrive," and dual graphics processors: a NVIDIA GeForce 9600M GT with 256 MB of dedicated GDDR3 SDRAM and a NVIDIA GeForce 9400M sharing 256 MB of DDR3 SDRAM with main memory. It also features an integrated iSight camera and an LED-backlit 15.4-inch widescreen TFT active-matrix "glossy" display with a 1440x900 resolution.
Connectivity comprises AirPort Extreme (802.11a/b/g/n), Bluetooth 2.1+EDR, Gigabit Ethernet, a FireWire "800" port, two USB 2.0 ports, optical digital/analog audio in/out, a "Mini DisplayPort" for external displays up to 2560x1600, and an SD card slot. It does not have an ExpressCard/34 slot.
This model uses a "Unibody" case design, milled from a single block of aluminum, which is essentially the same as the previous 15-inch MacBook Pro models it replaced. It retains the backlit keyboard and "no button" glass "multi-touch" trackpad with four-finger gesture support and programmable zones. Although the internal architecture is very similar, there are notable differences. The "Mid-2009" 15-inch models feature an improved display with a reported "60% greater color gamut" and a non-swappable battery that provides 7 hours of life (up from 5 hours). They also include the aforementioned SD card slot but omit the previously standard ExpressCard/34 slot.
