The Apple Mac mini "Core i5" 3.0 (Late 2018/Space Gray) is built around a 14 nm "Coffee Lake" 3.0 GHz Intel "Core i5" (8500B) processor, featuring six independent processor "cores" on a single chip and a 9 MB shared L3 cache. It comes with 8 GB of user-upgradable 2666 MHz DDR4 PC4-21300 SDRAM, onboard PCIe-based SSD storage of 256 GB or 512 GB (with 512 GB becoming standard from March 18, 2020), and an integrated Intel UHD Graphics 630 processor that shares system memory.
Connectivity options include four Thunderbolt 3 (USB-C) ports, two USB 3.1 ports, an HDMI 2.0 port, Gigabit Ethernet (upgradable to NbaseT/10 Gigabit Ethernet at purchase), 802.11ac Wi-Fi (802.11a/b/g/n compatible), Bluetooth 5.0, and a 3.5 mm headphone jack.
Compared to its much older forerunner, this model maintains a similar appearance, aside from its dark "Space Gray" color. However, it incorporates a far more advanced processor and system architecture, along with more modern connectivity. It also features user-upgradable RAM, although the storage is not upgradable.
All Mac mini systems are sold by default without a display, keyboard, or mouse, but numerous Apple and third-party accessories are available.
