The iMac "Core i7" 3.1 21.5-Inch Aluminum (Late 2013) technically is a "configure-to-order" configuration of the iMac "Core i5" 2.9 21.5-Inch Aluminum (Late 2013), 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 2013/Haswell) features a 22 nm "Haswell" Quad Core 3.1 GHz Intel "Core i7" (4770S) 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 750M graphics processor with 1 GB 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, 802.11ac 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.
The "Late 2013" iMac models shipped with a compact aluminum Apple Wireless Keyboard and the choice of either a multi-touch "Magic Mouse," a multi-touch "Magic Trackpad," or a traditional wired Apple mouse.

| Processor Speed: |
3.1 GHz |
Processor Type: |
Core i7 (I7-4770S) |
| Details: |
This model is powered by a 22 nm, 64-bit "Fourth Generation" Intel Core i7 "Haswell" (4770S) 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).

*Officially, Apple provides no information about whether or not the processor in this model can be upgraded and the company does not intend for one to upgrade the processor either.
However, as first reported by iFixit, in a late addition to their teardown of the entry-level iMac "Core i5" 2.7 21.5" (Late 2013) model -- which has a soldered processor and cannot be upgraded -- the processor in this model is mounted on a LGA 1150 socket and can be physically upgraded with another compatible processor.

Unfortunately, accessing these slots requires one to pry off the display that is glued to the case and remove the logic board.
