The MacBook Pro "Core i5" 2.3/2.4 13-Inch (2011/Thunderbolt) features a 32 nm "Sandy Bridge" 2.3 GHz Intel "Core i5" processor (2415M), with two independent processor "cores" on a single silicon chip, a 3 MB shared level 3 cache, 4 GB of 1333 MHz DDR3 SDRAM (PC3-10600) installed in pairs (two 2 GB modules), a 320 GB Serial ATA (5400 RPM) hard drive, an 8X DL "SuperDrive", an Intel HD Graphics 3000 graphics processor that shares 384 MB of memory with the system, an integrated FaceTime HD webcam, 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, audio in/out, an SDXC card slot, and a new "Thunderbolt" port that is backwards compatible with Mini DisplayPort and, likewise, supports an external display at 2560x1600 and passes an audio signal. Thunderbolt also supports other peripherals that use the Thunderbolt standard which provides up to 10 Gbps of bandwidth in both directions.
This model is powered by a 32 nm, 64-bit Intel Mobile Core i5 "Sandy Bridge" (I5-2415M) processor which includes two independent processor "cores" on a single silicon chip. Each core has a dedicated 256k level 2 cache, shares 3 MB of level 3 cache, and has an integrated memory controller (dual channel).
This system also supports "Turbo Boost 2.0" -- which "automatically increases the speed of the active cores" to improve performance when needed -- and "Hyper Threading" -- which allows the system to recognize four total "cores" or "threads" (two real and two virtual).
