Comparison MSI B350M PRO-VDH vs Asus PRIME B350M-A

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.

The presence of its own LED backlight on the motherboard. This feature does not affect the functionality of the "motherboard", but gives it an unusual appearance. Therefore, it hardly makes sense for an ordinary user to specifically look for such a model (a motherboard without backlighting is enough for him), but for modding lovers, backlighting can be very useful.

LED backlighting can take the form of individual lights or LED strips, come in different colours (sometimes with a choice of colours) and support additional effects — flashing, flickering, synchronization with other components (see "Lightning synchronization"), etc. Specific features depend on the motherboard model.

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.

Number of SATA 3 ports on the motherboard.

SATA is now the standard interface for connecting internal drives (mainly HDDs) and optical drives. One device is connected to one such connector, so the number of SATA ports corresponds to the number of internal drives / drives that can be connected to the motherboard through such an interface. A large number ( 6 SATA ports and more) is necessary in case of active use of several hard drives and other peripherals. For domestic use, 4 is enough. SATA 3, as the name suggests, is the third version of this interface, operating at a total speed of about 6 Gbps; the useful speed, taking into account the redundancy of the transmitted data, is about 4.8 Mbps (600 MB / s) — that is, twice as much as in SATA 2.

Note that different SATA standards are quite compatible with each other in both directions: older drives can be connected to newer ports, and vice versa. The only thing is that the data transfer rate will be limited by the capabilities of the slower version, and in some cases it may be necessary to reconfigure the drives with hardware (switches, jumpers) or software. It is also worth saying that SATA 3 is the newest and most advanced variation of SATA today, but the capabilities of this standard are not enough to unlock the full potential of high-speed SSDs. Therefore, SATA 3 is mainly used for hard drives and low-cost SSDs, faster drives ar...e connected to specially designed connectors like M.2 or U.2 (see below).

The presence of reinforced steel PCI-E connectors on the "motherboard".

Such connectors are found mainly in gaming (see "In the direction") and other advanced varieties of motherboards, designed to use powerful graphics adapters. Steel slots are usually made PCI-E 16x, just designed for such video cards; in addition to the slot itself, its attachment to the board also has a reinforced design.

This feature offers two key advantages over traditional plastic connectors. Firstly, it allows you to install even large and heavy video cards as reliably as possible, without the risk of damaging the slot or board. Secondly, the metal connector plays the role of a protective screen and reduces the likelihood of interference; this is especially useful when using multiple video cards installed side by side.

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.

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).

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.

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).
