The MacBook Pro "Core i7" 2.2 17-Inch (Early 2011/Thunderbolt) features a 32 nm "Sandy Bridge" 2.2 GHz Intel "Core i7" processor (2720QM), with four independent processor "cores" on a single silicon chip, a 6 MB shared level 3 cache, 4 GB of 1333 MHz DDR3 SDRAM (PC3-10600) installed in pairs (two 2 GB modules), a 750 GB Serial ATA (5400 RPM) hard drive, an 8X DL "SuperDrive", dual graphics processors -- an AMD Radeon HD 6750M with 1 GB of dedicated GDDR5 memory and an Intel HD Graphics 3000 graphics processor that shares 384 MB of memory with the system -- and an integrated FaceTime HD webcam. The standard configuration of this model has an LED-backlit 17.0" widescreen TFT active-matrix "glossy" display (1920x1200 native resolution), but it also was offered with an "anti-glare" (matte) display for US$50 more.

Thunderbolt also supports other peripherals that use the Thunderbolt standard which provides up to 10 Gbps of bandwidth in both directions.
