"Core i7" 3.1 21.5-Inch (Late 2012) [My collection]	Core i7 (I7-3770S)	3.1 GHz	Integrated	PC3-12800 DDR31	1600 MHz	23	None	16 GB2	8 GB
Notes: 1 By default, this system has 8 GB of 1600 MHz DDR3 SDRAM. Apple does not intend for one to upgrade the RAM in this system. However, as first discovered by site sponsor OWC, this system has two SO-DIMM slots (204-pin). Unfortunately, accessing these slots requires one to pry off the display that is glued to the case and remove the logic board. Also see: How do you upgrade the RAM in the "Late 2012" Tapered Edge Aluminum iMac models? Is it even possible? What type of RAM do they use? How much RAM does each model actually support? 2 8 GB of RAM is standard and it could be upgraded at the time of purchase to 16 GB for an additional US$200. Although Apple does not intend for one to upgrade the RAM after purchase, and doing so is difficult, it is possible. In the US (and many other countries), site sponsor Other World Computing sells memory -- as well as other upgrades -- for this iMac. In the UK, site sponsor Flexx sells memory and other upgrades for this iMac. In Australia, site sponsor RamCity sells memory and other upgrades for this iMac. In Southeast Asia, site sponsor SimplyMac.sg sells memory and other upgrades for this iMac. Also see: Actual Max RAM of All G3 & Later Macs. 3 There are two RAM slots, but access is difficult.

Notes: 1 68LC040*  2 The Macintosh WGS 60 models have a 32-bit processor and a 32-bit data path. The first version has a 20 MHz 68LC040 processor and the second has a 25 MHz 68040 processor. Sometimes these models are designated as having a 40 or 50 MHz processor, since the clock input runs at 40 or 50 MHz. However, the processors themselves are not "clock doubled," so technically each only is a 20 or 25 MHz processor.

Notes: 1 Apple officially reports that the iPhone 5s uses an "Apple A7" processor and boasts that it is the "world's first smartphone with 64-bit desktop-class architecture," but does not specify clockspeed or number of cores. Apple also reports that the device has an "M7 motion coprocessor" that "continuously measures motion data" and includes accelerometer, gyroscope, and compass functions. However, the always excellent AnandTech was first to determine that the Apple A7 processor is a ARMv8 derivative of Apple's "Swift" dual core architecture called "Cyclone" and it runs at 1.3 GHz. It also is 28 nm, has a 64k/64k level 1 (instruction/data) cache and a 1 MB level 2 cache. Also see: How fast are the iPhone 5c and iPhone 5s models compared to one another?
