The Apple Mac mini "Core i5" 2.5 (Late 2012/Aluminum Unibody) features a 22-nm "Ivy Bridge" 2.5 GHz Intel "Core i5" (3210M) processor with two independent processor "cores" on a single chip, a 3 MB shared level 3 cache, and Intel HD Graphics 4000 which shares system memory. It does not have an internal optical drive, although an external one was offered for US$79.
Connectivity includes a Firewire "800" port, four USB 3.0 ports, HDMI, Thunderbolt, combined "audio line in (digital/analog)" and combined "audio line out/headphone (digital/analog)" minijacks, a 10/100/1000Base-T Gigabit Ethernet port, 802.11a/b/g/n Wi-Fi, Bluetooth 4.0, and an SDXC card slot.
Compared to its predecessor, this model looks identical, but it has a faster internal architecture with a faster processor, faster graphics, faster RAM, and USB 3.0 ports.
