The Apple MacBook Pro "Core 2 Duo" 2.4 15-Inch (Santa Rosa) features a 2.4 GHz "Core 2 Duo" processor (T7700), with two independent processor "cores", a 4 MB shared "on chip" level 2 cache, an 800 MHz frontside bus, 2.0 GB of 667 MHz PC2-5300 DDR2 SDRAM, a 160 GB (5400 RPM) hard drive with "Sudden Motion Sensor" technology, and an 8X dual-layer DVD�RW/CD-RW SuperDrive. It also includes a NVIDIA GeForce 8600M GT graphics processor with 256 MB of GDDR3 SDRAM and dual-link DVI functionality, and a new heralded "mercury-free power-efficient LED-backlit" 15.4" widescreen 1440x900 "matte" or "glossy" TFT active-matrix display. WIth the exception of the display, the 15-Inch "Santa Rosa" MacBook Pro models effectively are identical externally to the previously released "Core 2 Duo" systems -- with the same fiber-optic-based "ambient light sensor" that adjusts keyboard illumination and screen brightness, "scrolling TrackPad", "MagSafe" power connector, integrated iSight video camera (although it is an unadvertised 1.3 megapixels), and included Apple Remote. Connectivity includes the same ExpressCard/34 slot, AirPort Extreme (although the "Santa Rosa" models have 802.11n enabled by default), Bluetooth 2.0+EDR, Gigabit Ethernet, FireWire "400" port, Firewire "800" port, two USB 2.0 ports, optical digital audio in/out, and DVI out.
