The iMac "Core i7" 3.1 21.5-Inch Aluminum (Late 2012) technically is a "configure-to-order" configuration of the iMac "Core i5" 2.9 21.5-Inch Aluminum (Late 2012), but also is documented as a separate model for reader convenience. Other than processor (and the corresponding level 3 cache), these two models are identical.
The iMac "Core i7" 3.1 21.5-Inch Aluminum (Late 2012) features a 22 nm Quad Core 3.1 GHz Intel "Core i7" I7-3770S (Ivy Bridge) processor with four independent processor cores on a single chip, an 8 MB shared level 3 cache, 8 GB of 1600 MHz DDR3 SDRAM (which is not intended to be upgraded after purchase), a 1 TB (5400 RPM) hard drive, and a NVIDIA GeForce GT 650M graphics processor with 512 MB of dedicated GDDR5 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, 802.11n, and Bluetooth 4.0.
In addition to a thinner case design, the "Late 2012" iMac models have faster processors, faster architectures, faster RAM (although it cannot be upgraded easily in the 21.5-Inch models), faster graphics, as well as different connectivity than the "Mid-2011" iMac line replaced.
The "Late 2012" iMac models include a compact aluminum Apple Wireless Keyboard and the choice of either a multi-touch "Magic Mouse" or a multi-touch "Magic Trackpad" that "enables users to scroll smoothly up and down a page with inertial scrolling, pinch to zoom in and out, rotate an image with their fingertips and swipe three fingers to flip through a collection of web pages or photos."

| Processor Speed: |
3.1 GHz |
Processor Type: |
Core i7 (I7-3770S) |
| Details: |
This model is powered by a 22 nm, 64-bit Intel Core i7 (3770S) "Ivy Bridge" 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 8 MB level 3 cache. It also supports Turbo Boost 2.0 (up to 3.9 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) -- and "Hyper Threading" -- which allows the system to recognize eight total "cores" or "threads" (four real and four virtual).
