ORIGINAL PICTURE

Haswell/Crystalwell" Quad Core 2.7 GHz Intel "Core i5" (4570R) processor with four independent processor cores on a single chip, a 4 MB shared level 3 cache, 8 GB of 1600 MHz DDR3 SDRAM (which is not intendedto be upgraded after purchase), a 1 TB (5400 RPM) hard drive, and an "integrated" Intel Iris Pro 5200 graphics processor with 128 MB of "Crystalwell" embedded DRAM (and shared system memory). It also has a built-in "FaceTime HD" webcam and stereo speakers, but lacks an optical drive.

This model has a 21.5" 1920x1080 LED-backlit 16:9 widescreen IPS display with the "cover glass fully laminated to the LCD and anti-reflective coating." The rear of the case is aluminum and is thicker in the middle and tapers to a razor thin 5 mm at the edges.

Connectivity includes four USB 3.0 ports, dual Thunderbolt ports, Gigabit Ethernet, 802.11ac Wi-Fi (802.11a/b/g/n compatible), and Bluetooth 4.0.

Compared to its predecessor, this model essentially has the same external enclosure, but it has a much more efficient "Fourth Generation" processor and architecture, as well as faster graphics, faster Wi-Fi, and the option of faster storage. 

This model is powered by a 22 nm, 64-bit "Fourth Generation" Intel Mobile Core i5 "Haswell/Crystalwell" (4570R) processor with quad cores (four independent processor cores on a single silicon chip, each with one thread). Each core has a dedicated 256k level 2 cache and all processor cores share a single 4 MB level 3 cache. It also supports Turbo Boost 2.0 (up to 3.2 GHz) -- which "automatically boosts the processor speed based on workload" (so if an application is only using one of the four cores it will automatically increase the speed of the core in use and turn off the unused cores)
