Power phases

The number of processor power phases provided on the motherboard.

Very simplistically, phases can be described as electronic blocks of a special design, through which power is supplied to the processor. The task of such blocks is to optimize this power, in particular, to minimize power surges when the load on the processor changes. In general, the more phases, the lower the load on each of them, the more stable the power supply and the more durable the electronics of the board. And the more powerful the CPU and the more cores it has, the more phases it needs; this number increases even more if the processor is planned to be overclocked. For example, for a conventional quad-core chip, only four phases are often enough, and for an overclocked one, at least eight may be needed. It is because of this that powerful processors can have problems when used on inexpensive low-phase motherboards.

Detailed recommendations on choosing the number of phases for specific CPU series and models can be found in special sources (including the documentation for CPU itself). Here we note that with numerous phases on the motherboard (more than 8), some of them can be virtual. To do this, real electronic blocks are supplemented with doublers or even triplers, which, formally, increases the number of phases: for example, 12 claimed phases can represent 6 physical blocks with doublers. However, virtual phases are much inferior to real ones in terms of capabilities — in fact, t...hey are just additions that slightly improve the characteristics of real phases. So, let's say, in our example, it is more correct to speak not about twelve, but only about six (though improved) phases. These nuances must be specified when choosing a motherboard.

VRM heatsink

The design of the motherboard has a separate heatsink for VRM.

VRM is a voltage regulation module through which power from a computer power supply is supplied to the processor. This module steps down the standard power supply voltage (+5V or +12V) to a lower value required by the processor (usually just over 1V). At high loads, the voltage regulator can get very hot, and without a specialized cooling system, the matter can end with overheating and even burnout of parts. The VRM heatsink reduces the likelihood of such situations; it can be useful for any CPU, and highly desirable if the board is planned to be used with a powerful high-end processor (especially overclocked).

Size (HxW)

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.

1x PCI-E slots

Number of PCI-E (PCI-Express) 1x slots installed on the motherboard. There are motherboards for 1 PCI-E 1x slot, 2 PCI-E 1x slots, 3 PCI-E 1x ports and even more.

The PCI Express bus is used to connect various expansion cards — network and sound cards, video adapters, TV tuners and even SSD drives. The number in the name indicates the number of PCI-E lines (data transfer channels) supported by this slot; the more lines, the higher the throughput. Accordingly, PCI-E 1x is the basic, slowest version of this interface. The data transfer rate for such slots depends on the PCI-E version (see "PCI Express Support"): in particular, it is slightly less than 1 GB / s for version 3.0 and slightly less than 2 GB / s for 4.0.

Separately, we note that the general rule for PCI-E is as follows: the board must be connected to a slot with the same or more lines. Thus, only single-lane boards will be guaranteed to be compatible with PCI-E 1x.

USB 2.0

The number of USB 2.0 connectors provided on the motherboard.

USB connectors (all versions) are used to connect to the "motherboard" USB ports located on the front panel of the case. With a special cable, such a port is connected to the connector, while one connector, usually, works with only one port. In other words, the number of connectors on the motherboard corresponds to the maximum number of front USB connectors that can be used with it.

Specifically, USB 2.0 is the oldest version widely used nowadays. It provides data transfer rates up to 480 Mbps, is considered obsolete and is gradually being replaced by more advanced standards, primarily USB 3.2 gen1 (formerly USB 3.0). Nevertheless, a lot of peripherals are still being produced under the USB 2.0 connector: the capabilities of this interface are quite enough for most devices that do not require a high connection speed.

USB 3.2 gen1

The number of USB 3.2 gen1 connectors provided on the motherboard.

USB connectors (all versions) are used to connect to the "motherboard" USB ports located on the outside of the case (usually on the front panel, less often on the top or side). With a special cable, such a port is connected to the connector, while one connector, usually, works with only one port. In other words, the number of connectors on the motherboard corresponds to the maximum number of case USB connectors that can be used with it. At the same time, we note that in this case we are talking about traditional USB A connectors; connectors for newer USB-C are mentioned separately in the specifications.

Specifically, USB 3.2 gen1 (formerly known as USB 3.1 gen1 and USB 3.0) provides transfer speeds of up to 4.8 Gbps and more power than the earlier USB 2.0 standard. At the same time, USB Power Delivery technology, which allows you to reach power up to 100 W, is usually not supported by this version of USB A connectors (although it can be implemented in USB-C connectors).

LAN controller

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).

USB 3.2 gen1

The number of native USB 3.2 gen1 connectors provided on the back of the motherboard. In this case, traditional, full-size USB A ports are meant.

USB 3.2 gen1(formerly known as USB 3.1 gen1 and USB 3.0) is a direct successor and development of the USB 2.0 interface. The main differences are a 10-fold increase in the maximum data transfer rate — 4.8 Gbps — as well as higher power supply, which is important when connecting several devices to one port through a splitter (hub). At the same time, peripherals of other versions can be connected to this connector.

The more connectors provided in the design, the more peripheral devices can be connected to the motherboard without the use of additional equipment (USB splitters). There are boards on the market that have more than 4 USB 3.2 gen1 ports on the back panel. At the same time, we note that in addition to the connectors on the rear panel, connectors on the board itself (more precisely, ports on the case connected to such connectors) can also provide a USB connection. See below for more on this.

USB 3.2 gen2

The number of native USB 3.2 gen2 connectors provided on the back of the motherboard. In this case, we mean traditional, full-size USB A ports.

USB 3.2 gen2(formerly known as USB 3.1 gen2 and simply USB 3.1) is the evolution of USB 3.2 after version 3.2 gen1 (see above). This standard provides connection speeds up to 10 Gbps, and to power external devices in such connectors, USB Power Delivery technology (see below) can be provided, which allows you to output up to 100 W per device (however, Power Delivery support is not mandatory, its presence should be specified separately). Traditionally for the USB standard, this interface is backwards compatible with previous versions — in other words, you can easily connect a device supporting USB 2.0 or 3.2 gen1 to this port (unless the speed will be limited by the capabilities of a slower version).

The more connectors provided in the design, the more peripheral devices can be connected to the motherboard without the use of additional equipment (USB splitters). In some models of motherboards, the number of ports of this type is 5 or even more. At the same time, we note that in addition to the connectors on the rear panel, connectors on the board itself (more precisely, ports on the case connected to such connectors) can also provide a USB connection. See below for more on this.
