iMac Late 2013

Initially a "configure-to-order" version of the iMac "Core i5" 3.4 27-Inch Aluminum (Late 2013), the iMac "Core i7" 3.5 27-Inch was also offered as a standard configuration. Except for the processor and its corresponding L3 cache, the two models can be identical.

This iMac (Late 2013/Haswell) is powered by a 22 nm "Haswell" Quad Core 3.5 GHz Intel "Core i7" (4771) processor, with four independent cores on a single chip and an 8 MB shared L3 cache. It includes 8 GB of 1600 MHz DDR3L SDRAM (PC3-12800) in a dual-module setup, a 1 TB (7200 RPM) hard drive (or a 3 TB "Fusion" Drive in the standard MF125LL/A configuration), and a NVIDIA GeForce GTX 775M graphics processor with 2 GB of dedicated GDDR5 memory. It features a built-in "FaceTime HD" webcam and stereo speakers, but omits an optical drive.

It sports a 27" 2560x1440 LED-backlit 16:9 widescreen IPS display with "cover glass fully laminated to the LCD and anti-reflective coating." The aluminum rear case tapers to a slim 5 mm at the edges. Connectivity includes four USB 3.0 ports, dual Thunderbolt ports, Gigabit Ethernet, 802.11ac Wi-Fi (compatible with 802.11a/b/g/n), and Bluetooth 4.0.

Compared to its predecessor, this model shares a nearly identical external design but offers a much more efficient "Fourth Generation" processor and architecture, plus faster graphics, faster Wi-Fi, and optional faster storage.

The "Late 2013" iMacs came with a compact aluminum Apple Wireless Keyboard and a choice of a multi-touch "Magic Mouse," a "Magic Trackpad," or a traditional wired Apple mouse.

As the top-tier build-to-order 27-inch iMac, this machine featured a Haswell Core i7 processor, delivering exceptional multi-threaded performance with Hyper-Threading. [15] Paired with the NVIDIA GeForce GTX 775M graphics, it demonstrated a clear performance advantage over Core i5 models in demanding tasks like video editing and 3D rendering, earning immense support from professional users. The optional NVIDIA GeForce GTX 780M further boosted its capabilities. [20] The ease of RAM upgrades, the high-speed Fusion Drive, and support for 802.11ac Wi-Fi were also factors that enhanced this model's value. [15, 25] It was judged to be the pinnacle of non-Retina iMacs in terms of performance and expandability.
