Apple iMac 27-Inch RetinaThe iMac "Core i7" 4.0 27-Inch Aluminum (Late 2014/Retina 5K) technically is a "configure-to-order" configuration of the iMac "Core i5" 3.5 27-Inch Aluminum (Late 2014/Retina 5K), 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" 4.0 27-Inch Aluminum (Late 2014/Retina 5K) features a 22 nm "Haswell" Quad Core 4.0 GHz Intel "Core i7" (4790K) processor with four independent processor cores on a single chip, an 8 MB shared level 3 cache, 8 GB of 1600 MHz DDR3 SDRAM (PC3-12800) installed in pairs (two 4 GB modules), a 1 TB "Fusion Drive" (1 TB hard drive and 128 GB SSD), and a AMD Radeon R9 M290X graphics processor with 2 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 27" 5120x2880 LED-backlit 16:9 widescreen IPS display that Apple has dubbed "Retina 5K". 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 2 ports, Gigabit Ethernet, 802.11ac Wi-Fi (802.11a/b/g/n backwards compatible), and Bluetooth 4.0.

Compared to the Late 2013 models introduced previously, this model essentially has the same external enclosure, but it has a much higher resolution display as well as a modestly faster processor, a higher performance graphics processor, a "Fusion Drive" by default, and Thunderbolt 2 support.

The "Late 2014" 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.

4.0 GHz Core i7 (I7-4790K)
Details: This model is powered by a 22 nm, 64-bit "Fourth Generation" Intel Core i7 "Haswell" (4790K) 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 4.4 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).
