A mini PC (or miniature PC, nettop, or Smart Micro PC) is a small-sized, inexpensive, low-power,^{[citation needed]} legacy-free desktop computer designed for basic tasks such as web browsing, accessing web-based applications, document processing, and audio/video playback.^[1]^[2]^[3]

The word nettop is a portmanteau of network and desktop. It is the desktop counterpart of the netbook. Modern (c. 2020) mini PCs or small form factor PCs can be much more powerful, being equipped with high-end laptop components or mid-range desktop components.^[4]^[5]

Compared with ordinary desktop computers, nettops are not only smaller and less expensive,^[6] but they also consume much less power. For example, CompuLab's fit-PC2 consumes no more than 8 watts of power^[7] whereas a typical desktop would easily consume more than 100 watts of power; consequently, nettops require significantly less cooling and may even be completely fanless. Some do not have an optical disk drive and use a solid-state drive, making them completely silent. The tradeoff is that the hardware specifications and processing power are usually reduced^[8] and hence make nettops less appropriate for running complex or resource-intensive applications.

Hardware

There are several platforms that are primarily intended for nettops and netbooks:

Intel's Atom platform^[9]
Nvidia's Ion platform^[10]
Intel's Core platform
AMD's APU platform
Apple's Mac Mini
VIA's Trinity Platform^[11]

Some nettops have also adopted system-on-a-chip designs. Although many major parts such as chipsets, video cards and storage devices can also be found on desktops, the CPUs that are put inside nettops are the fundamental component that differentiate them from normal desktops. The list below contains a range of hardware components that a typical nettop may be assembled from.

AMD Radeon HD 6310

ATI Radeon HD 4530

PowerVR
Chipset
945GSE and 945GC Express chipsets

MCP79MX (integrated GeForce 9400M G GPU; Nvidia Ion platform)

VIA VX800 IGP Chipset

Solid-state drive (SSD)
Network
Ethernet and/or Wi-Fi
I/O ports
LAN, USB, video out, audio out

Intel's Atom processor has been adopted by several hardware manufacturers, such as ASUS, MSI, and Sony, for nettops. Nvidia has also released its first generation ION platform, which puts GeForce 9400M Motherboard GPU alongside the Atom processor to provide better high definition video playback ability and lower power consumption.^[12] In addition, Nvidia has announced that it will support VIA's CPUs this year.^[13] To further reduce the manufacturing cost and improve power efficiency, many manufacturers and start-up companies have chosen to use CPUs that were originally targeted at embedded computing devices such as AMD's Geode and ARM Cortex-based CPUs.

Operating systems

Many net-top models are x86-processor-based and as such are capable of running standard PC OSes. There are also operating systems designed specifically for nettops and other machines in the same performance class. Some high-end nettops are capable of running Windows 10.^[14] Google's ChromeOS and Android are other options. Although Google's Android was originally designed for smartphones, it has also taken a seat in the nettop market.^[15]

Linux is beginning to be the favorite choice of nettop users (considering the high commercial use of these machines), the flexibility and low-requirement capabilities of the OS are perfect for the product.^{[citation needed]}

Market

Nettops fell into Intel's category of "Basic PC", which usually cost from $100 to $299.^[16] Intel described nettops as a large potential market at that time. Nettops were said to be able serve as an affordable first computer for people in developing countries, or as an environmentally friendly choice as a secondary computer for people in developed countries.^[17]
