Next Unit of Computing

Next Unit of Computing (NUC) is a line of small-form-factor barebone computer kits designed by Intel. It was previewed in 2012 and launched in early 2013. The NUC has developed over ten generations, spanning from Sandy Bridge-based Celeron CPUs in the first generation through Ivy Bridge-based Core i3 and i5 CPUs in the second generation to Gemini Lake-based Pentium and Celeron CPUs and Kaby Lake-based Core i3, i5, and i7 CPUs in the seventh and eighth generations. The NUC motherboard usually measures approximately 4 xx, although some models have had different dimensions.

The barebone kits consist of the board, in a plastic case with a fan, an external power supply, and a VESA mounting plate. Intel also sells bare NUC motherboards, which have a built-in CPU. However, the price of a NUC motherboard is very close to the corresponding cased kit; third-party cases for the NUC boards are also available.

In July 2023, Intel announced that it would no longer develop NUC mainboards and matching mini PCs. They subsequently announced that NUC products will continue to be built by ASUS, under non-exclusive license.

Sandy Bridge
The first generation Intel NUC launched in the first quarter of 2013. This UCFF motherboard and system kit are codenamed Ski Lake (DCP847SK) and Deep Canyon (DCCP847DY) respectively.

Ivy Bridge
The base UCFF motherboard and kit without Thunderbolt or USB 3 are codenamed Golden Lake (D33217GK) and Ice Canyon (DC3217IY) respectively. The Thunderbolt capable UCFF motherboard and kit are codenamed Campers Lake (D33217CK) and Box Canyon (DC3217BY) respectively. The USB 3 capable UCFF motherboard and kit are codenamed Rend Lake (D53427RK) and Horse Canyon (DC53427HY) respectively.

The stripped-down DC3217BY model has a signature red top cover and no Ethernet. This model, while stocks were still available, generally sold for a deep discount. The absence of Ethernet may be mitigated by using a USB 2.0 to 10/100 fast Ethernet dongle based upon the Kawasaki LSI one-chip adapter (KL5KUSB102, for example), or a similar dongle based upon a Realtek chip; the Kawasaki Logic dongle requires a proprietary driver for macOS X, whereas the driver for the Realtek dongle is built into macOS X. The DC3217BY runs macOS X (10.9, and any of its updates) flawlessly as the processor's HD4000 is fully supported by macOS X.

Bay Trail-M
This UCFF motherboard (DN2820FYB) and system kit (DN2820FYKH) model were codenamed Forest Canyon. The DN2820FYKH product itself is mis-marked DN2820FYK, but the retail package, all retail documentation, and Intel's web site correctly identify this product as DN2820FYKH. The "H" indicates support for internal 2.5" media, SSD or HDD. There is no "non-H" version of this product as it does not include an on-board mSATA connector, hence media which is external to the board is mandatory, and hence the "H" version.

This product introduced a new 12V 3A "wall wart" power supply in place of the previous 19V 3.42A laptop-style power brick and its IEC 60320-C5 "Mickey Mouse" type AC power cord. Four region-specific plug-on adapters, including North America and three overseas countries, are included in the retail package.

These models shipped with the problematic BIOS revision 13, however this revision did not recognise most low voltage SO-DIMMs and would report as having zero capacity. Keyboard escapes for BIOS interfacing had been problematic, legacy booting was not supported, and it had been elected to only include UEFI booting. BIOS revision 48 has been released and resolved the problems, enabling the recognition of most low voltage SO-DIMMs, keyboard escapes and legacy booting.

Reception and ecosystem
The NUC was seen by some reviewers as Intel's response to (or adoption of) the Apple Mac Mini format, although it is actually smaller, physically. Given its kit nature, other reviewers have seen it as a more powerful Raspberry Pi, particularly since the NUC boards could be bought without a case. The NUC can also be seen as an extension or continuation of Intel's earlier mobile-on-desktop (MoDT) initiative that was spearheaded by AOpen as early as 2004.

Most of the third-generation NUCs come in two case sizes, one with room for a 2.5-inch drive, and one without. The smaller case, although lacking room for a 2.5" drive, still has an internal SATA connector (including SATA power).  Some larger third-party cases have appeared that can fit such drives.

The Intel case is actively cooled with a fan. Silent PC Review notes that “The original Intel NUC had "the distinction of being the quietest fan-cooled mini-computer we've come across." The NUC D54250WYK [Haswell-based], with the same cooling system, sounds exactly the same. In normal use, you can't hear the fan until your ear is inches from the unit.” Nevertheless, passively cooled third-party cases have appeared on the market as well. Larger or metallic third-party cases also provide lower operating temperatures.

A review by the Tech Report of the pre-production 2012-vintage NUC found that the NUC would seize up after a few gigabytes were transferred over wireless and that the problem could be alleviated by better cooling of the NUC case. Intel later increased the default fan speed for production machines through a BIOS update (downloadable from Intel's web site for "early adopters").

Regarding power consumption, in their review of the D54250WYK with a Haswell i5-4250, Silent PC Review concluded that "An idle power level of just 6 W and typical use power barely into two digits is very impressive in one sense; in another sense, it's what you find in current Ultrabooks using similar components."

Other companies have subsequently adopted a form factor similar, but not identical, to Intel's NUC. For example, Gigabyte Technology launched their BRIX series, which attempts to differentiate itself using more powerful components, up to the i7-4770R processor, which embeds Intel Iris Pro Graphics.

Operating system support
NUCs support UEFI compatible operating systems, such as Microsoft Windows, as well as most distributions of Linux. Additionally, they can be used for virtualization with a variety of different hypervisor hosts; multiple NUCs can be used together to create a home lab for learning purposes.

It is technically possible, with some limitations in functionality, to install an unauthorized copy of MacOS on a NUC, creating a "Hackintosh". The pre-Haswell Core i3 and Core i5 NUCs will run OS X 10.9 Mavericks well.

Skylake and Broadwell-based NUC is also a supported device in Google Fuchsia OS.
