The general type of computer. In addition to classic desktop models (including gaming purposes), more unusual solutions are also found nowadays: monoblocks, nettops, microcomputers. Here are the features of each type:

— Desktop. Traditional desktop PCs, in other words, models that do not fit into any of the more specific categories. For the most part, they are not even desktop, but rather "below the table" — they are carried out in vertical cases, most often placed under the tabletop, horizontal system units are extremely rare among such devices.

— Game. A variety of desktop computers, designed for professional players and gamers-enthusiasts. Such models are necessarily equipped with a powerful hardware, which allows you to comfortably play even demanding modern games. In addition, they often provide various additional features that are useful for specialization: built-in overclocking tools, high-end customizable cooling systems, etc. Another feature of gaming PCs is a distinctive design, often quite original: in an “aggressive” style, with backlight, unusual body shape, transparent inserts, etc.

— Monoblock. Monoblocks are devices that combine a screen, system unit electronics, a set of connectors and acoustics in one case; in other words, these are monitors with built-in comp...uter “hardware”. This design has two main advantages. Firstly, the system initially has a display, and it is quite large and optimally suited to its configuration — so the user does not need to look for a separate screen. Secondly, such a computer takes up very little space — only slightly more than a monitor with the same screen size; and the absence of a separate system unit can be written down as an advantage. On the other hand, if in a regular PC the “system unit” and the monitor can be selected separately, at your discretion, then in monoblocks this is not possible — you have to get by with the combinations that the manufacturer initially offers. In addition, the possibilities for modification and upgrade for such models are noticeably more modest than for traditional ones, and there is no talk of replacing the screen at all.

— Nettop. Devices also known as "mini PCs". They are small and modestly equipped — in particular, a very limited set of ports. In addition, many nettops do not differ in performance and are designed mainly for working with documents, surfing the Internet and other simple tasks. However, there are also quite powerful performant solutions. Anyway, the main advantage of the nettop is compactness.

— Microcomputer. As the name suggests, this type of computer is extremely tiny—comparable in size to a flash drive—and looks more like portable adapters for external screens than stand-alone devices. The case of such an “adapter” usually has its own HDMI connector, which is used to connect to a monitor or TV; the same port provides power. And the case most often provides for a “mobile” energy-saving processor with integrated graphics, a compact SSD or eMMC drive, and wireless modules. Peripherals like keyboards and mice are connected mainly via Bluetooth, but many models have wired connectors like USB, and sometimes in quite a decent amount (2 or even 3). In general, such a device can be a good alternative to a tablet or laptop for those who often move between different workplaces — the main thing is that these places have appropriate screens for connection. The power of microcomputers, naturally, is low, but they are not designed for "heavy" tasks.

— Thin client. Thin clients are computers designed to be used in terminal mode for external servers. In this case, all resource-intensive calculations are performed by the server, and the functions of the thin client are limited to entering initial data and receiving results. Most of these computers do not involve independent work at all, but this is not a drawback, but a feature of specialization. In general, this format of work is not used in everyday life and in the ordinary business sphere, but it is perfect for some highly professional tasks. And since the thin client does not need high performance, it can be made as compact, lightweight and inexpensive as possible.

The form factor of a computer case characterizes, first of all, the internal volume. Main PC Form Factors:

— Midi Tower. A representative of the tower family (tower cases) of medium size — about 45 cm in height with a width of 15-20 cm, with the number of external bays from 2 to 4. Most popular for middle-class home PCs.

— Mini Tower. The most compact "vertical" case type, with a width of 15-20 cm, has a height of about 35 cm and (usually) less than 2 compartments with external access. Used mainly for office PCs that do not require high performance.

— Full Tower. The tower case is one of the largest form factors for PCs today: 15-20 cm wide, 50-60 cm high, with up to 10 externally accessible bays. Most often in this form factor running advanced high performance PCs

— Desktop. Enclosures designed for installation directly on the desktop. They often have the possibility of horizontal installation — in such a way that a monitor can be placed on top of the case — although there are also models that are installed strictly vertically. Anyway, "desktop" models are relatively small.

— Cube Case. Cases having a cubic or close to it shape. They can have different sizes and are intended for different types of motherboards, this point in each case should be clar...ified separately. Anyway, such cases have a rather original appearance, different from traditional "towers" and "desktops".

The model of the chipset used in the standard configuration of the PC.

A chipset can be described as a set of chips that provides the combined operation of the central processor, RAM, I / O devices, etc. It is this chipset that underlies any motherboard. Knowing the chipset model, you can find and evaluate its detailed characteristics; most users do not need such information, but for specialists it can be very useful.

The general type (specialization) of the processor installed in the PC.

— Desktop. Processors originally designed for full-sized desktop computers. The specific characteristics of such CPUs can vary quite widely; however, in general, they have higher processing power than mobile chips, as well as a wider range of additional features and special solutions to improve efficiency. And with the same actual performance, desktop solutions are much cheaper than mobile ones. The downside of these advantages is the relatively high energy consumption and heat dissipation. However, for full-sized PCs, these shortcomings are not critical, so almost all traditional desktop computers, as well as most all-in-ones (see "Type") are equipped with this particular type of processor; and for powerful gaming models, a desktop CPU is mandatory by definition. On the other hand, this category also includes rather economical and "cold" low-power chips, which are suitable for compact computers that do not require high performance, such as nettops and thin clients.

— Mobile. This term in this case refers to processors originally designed for laptops. Most of these CPUs use the same basic architecture as desktop models — x86. Their main differences are: on the one hand, reduced energy consumption, reduced clock frequencies and low heat generation, on the other hand, less computing power in general. However the actu...al characteristics of such processors may vary from model to model, some laptop solutions are not inferior to fairly advanced desktop ones; however, with similar capabilities, a laptop processor will cost significantly more. Thus, this type of CPU is mainly used in nettops and individual models of monoblocks (see "Type"), where it is difficult to use powerful cooling systems.
A rarer variety of mobile processors used in modern PCs are chips based on the basic ARM architecture. Such processors have even lower heat dissipation and power, and are also often implemented in the System-On-Chip format, when the CPU itself, RAM, wired and wireless connection controllers, and other components are combined in one chip. ARM solutions can be found in Android touchscreen all-in-ones (which are effectively "desktop tablets"), as well as in individual thin clients.

The specific model of the processor installed in the PC, or rather, its index within its series (see "Processor"). The full model name consists of the series name and this index — for example, Intel Core i3 3220; knowing this name, you can find detailed information about the processor (characteristics, reviews, etc.) and determine how suitable it is for your purposes.

The number of cores in a complete PC processor.

The core is a part of the processor designed to process one stream of commands (and sometimes more, for such cases, see "Number of threads"). Accordingly, the presence of several cores allows the processor to work simultaneously with several such threads, which has a positive effect on performance. However note that a larger number of cores does not always mean higher computing power — a lot depends on how the interaction between command streams is organized, what special technologies are implemented in the processor, etc. So, only chips of the same purpose (desktop, mobile) and similar series (see "Processor") can be compared by the number of cores.

In general, single-core processors are practically not found in modern PCs. Mainly desktop chips of the initial and middle level are made dual-core. Four cores are found both in desktop CPUs of the middle and advanced class, and in mobile solutions. And six-core and eight-core processors are typical for high-performance desktop processors used in workstations and gaming systems.

The number of threads supported by the bundled PC processor.

A thread in this case is a sequence of instructions executed by the kernel. Initially, each individual core is able to work with only one such sequence. However, among modern CPUs, more and more often there are models in which the number of threads is twice the number of cores. This means that the processor uses multi-threading technology, and each core works with two instruction sequences: when pauses occur in one thread, the core switches to another, and vice versa. This allows you to significantly increase performance without increasing the clock frequency and heat dissipation, however, such CPUs are also more expensive than single-threaded counterparts.

Clock speed of the CPU installed in the PC.

In theory, higher clock speeds have a positive effect on performance because they allow the CPU to perform more operations per unit of time. However, this indicator is rather weakly related to real productivity. The fact is that the actual capabilities of the CPU strongly depend on a number of other factors - the overall architecture, cache size, number of cores, support for special instructions, etc. As a result, you can compare by this indicator only chips from the same or similar series (see “CPU”), and ideally, also from the same generation. And that's pretty approximate.

Processor clock speed when running in TurboBoost or TurboCore mode.

Turbo Boost technology is used in Intel processors, Turbo Core — AMD. The essence of this technology is the same both there and there: if some of the cores work under high load, and some are idle, then some tasks are transferred from more loaded cores to less loaded ones, which improves performance. This usually increases the clock frequency of the processor; this value is indicated in this paragraph. See above for more information on clock speed in general.
