The iMac "Core i7" 3.5 27-Inch Aluminum (Late 2013) originally was offered as a "conﬁgure-to-order" conﬁguration of the iMac

"Core i5" 3.4 27-Inch Aluminum (Late 2013),

but was sold as a standard conﬁguration, too.

Other than processor (and the corresponding level 3 cache), these two models can be identical.

The iMac "Core i7" 3.5 27-Inch Aluminum (Late 2013/Haswell) features a 22 nm "Haswell" Quad Core 3.5 GHz Intel "Core i7"

(4771) 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 (7200 RPM) hard drive (or a 3 TB "Fusion" Drive for the standard MF125LL/A conﬁguration), and a NVIDIA GeForce GTX 775M 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" 2560x1440 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 include 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: 3.5 GHz Processor Type: Core i7 (I7-4771)

This model is powered by a 22 nm, 64-bit "Fourth Generation" Intel Mobile Core i7 "Haswell" (4771) 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).
