Comparison ASRock N68-GS4 FX R2.0 vs ASRock N68-GS4 FX

Motherboard dimensions in height and width. It is assumed that the traditional placement of motherboards is vertical, so in this case one of the dimensions is called not the length, but the height.

Motherboard sizes are largely determined by their form factors (see above), however, the size of a particular motherboard may differ slightly from the standard adopted for this form factor. In addition, it is usually easier to clarify the dimensions according to the characteristics of a particular motherboard than to look for or remember general information on the form factor. Therefore, size data can be given even for models that fully comply with the standard.

The third dimension — thickness — is considered less important for a number of reasons, so it is often omitted.

The number of PCI slots provided in the design of the motherboard.

These slots are used for expansion cards. At the same time, technically, this interface is considered obsolete — in particular, it is noticeably inferior to the newer PCI-E in terms of data transfer speed (up to 533 MB / s). Nevertheless, for some types of components (for example, sound cards), such features are quite enough; and the use of PCI allows you to leave free PCI-E slots that may be needed for more demanding peripherals. So even nowadays, both motherboards with PCI slots and components with such a connection can still be found on the market.

The name of the integrated graphics card (see above) installed in the motherboard. Knowing the name of the graphics module, you can, if necessary, easily find detailed information about it — full specifications, tests, reviews, etc.

The model of the audio chip (a module for processing and outputting sound) installed on the motherboard. Data on the exact name of the sound chip will be useful when looking for detailed information about it.

Modern "motherboards" can be equipped with fairly advanced audio modules, with high sound quality and extensive features, which makes them suitable even for gaming and multimedia PCs (although professional audio work will still most likely require a separate sound card). Here are the most popular modern audio chips: Realtek ALC887, Realtek ALC892, Realtek ALC1150, Realtek ALC1200, Realtek ALC1220, Realtek ALC4050, Realtek ALC4080, Supreme FX.

The most advanced audio format that the motherboard audio chip is capable of outputting to an external audio system. At the moment, almost all motherboards with audio chips support standard 2.0 stereo sound, and the most advanced format can be as follows:

— 4. The specific sound layout for the four channels may be different, but anyway, this option is two classic stereo channels, supplemented by two more — for example, centre and rear, or a pair of rear (left and right). This allows you to expand the sound stage and achieve greater volume than in classic stereo, while maintaining the low cost of the sound cards themselves. However, this option is rare, mainly in mini-STX boards (see "Form factor").

— 5.1. Six-channel sound: two front, centre and two rear channels, plus a subwoofer for bass and extra bass. Allows you to reproduce a fully surround sound, which is perceived by the listener not only in front, but also behind him. One of the most popular multi-channel audio formats today.

— 7.1. The development of the idea of surround sound, laid down by the 5.1 format. In addition to the standard six-channel configuration (centre, front pair, rear pair and subwoofer), it provides two more speakers. The place of their installation may be different, depending on the specific eight-channel sound scheme used: above the front or rear pair, in the form of a centre-rear pair, on the sides of the listener, etc. Anyway, eight-channel circuits allow more...accurate sound direction reproduction.

— 9.1. The most advanced version of acoustics found in motherboards today. Similar to 7.1, this standard includes 6 channels according to the 5.1 scheme plus additional speakers — only in this case there are four of them, which gives even more opportunities to expand the surround sound.

Model of the LAN controller installed in the motherboard.

The LAN controller provides data exchange between the card and the network port(s) of the computer. Accordingly, both general characteristics and individual features of the network functionality of the "motherboard" depend on the characteristics of this module: support for special technologies, connection quality in case of unstable communication, etc. Knowing the model of the LAN controller, you can find detailed data on it — including including practical reviews; this information is rarely needed by the average user, but it can be useful for online game enthusiasts and for some specific tasks.

Thus, the LAN controller model is specified mainly in cases where it is a rather advanced solution that is noticeably superior to standard models. Such solutions are currently produced mainly under the brands Intel(middle level), Realtek(relatively simple models), Aquntia and Killer(mostly advanced solutions).

The type of connector for powering the processor installed on the motherboard.

Most modern boards use a 4-pin connector, and most power supplies in ATX cases are also designed for it. In addition, there are other types of power connectors, they all have an even number of pins — 2, 6 or 8. Two-pin power is used mainly in motherboards of miniature form factors like thin mini-ITX, designed for low-power processors. 8-pin connectors, on the contrary, are designed to power the most powerful modern processors. It is believed that such a connector provides a more stable power supply and more precise tuning of its parameters. But connectors for 6 pins are not found separately, they usually complement 8-pin connectors in high-performance motherboards, in particular, gaming ones.

Also note that some boards have 2 or even 3 power connectors — most often in the format 8 + 4, 8 + 8 and 8 + 8 + 6 pins. This functionality is designed for high-end CPUs with high power and power consumption, for which one connector is not enough. There is another specific option — “motherboards” without a separate processor power supply : these are models equipped with an integrated CPU, which receives energy through its own board circuits without a sp...ecial power connector.
