Comparison Asus PRIME H310M-R R2.0 vs Gigabyte H310M S2 2.0 rev. 1.0

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 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.

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 motherboard has its own DVI output; this clause also specifies the specific form of this interface.

Such an output is intended for transmitting video from an integrated graphics card (see above) or a processor with integrated graphics (we emphasize that it is impossible to output a signal from a discrete graphics card through the motherboard chipset). As for DVI specifically, this is a standard originally created for digital video devices, however, it also allows an analogue signal format, depending on the type. In modern computer technology, including motherboards, you can find two types of DVI:

— DVI-D. A standard that provides for the transmission of a signal only in digital form. Depending on the supported mode, the maximum resolution of such video can be 1920x1200 (single-link Single Link) or 2560x1600 (two-channel Dual Link); however, Single Link plugs can be connected to Dual Link ports, but not vice versa. Also note that such connectors are compatible with HDMI via adapters, while in some cases even sound transmission may be provided (although this function is not initially supported in DVI-D, and its availability should be specified separately).

— DVI-I. A standard that combines the DVI-D described above with analogue DVI-A and allows the signal to be output in both digital and analogue formats. DVI-A in its characteristics corresponds to VGA (see above): it supports resolutions up to 1280x1024...inclusive and allows you to connect VGA screens through a simple adapter.

The motherboard has its own HDMI output.

Such an output is intended for transmitting video from an integrated graphics card (see above) or a processor with integrated graphics (we emphasize that it is impossible to output a signal from a discrete graphics card through the motherboard chipset). As for HDMI specifically, it is a combined digital video/audio interface specifically designed to work with HD resolutions and multi-channel audio. Today it is the most common of these interfaces, HDMI support is almost mandatory for video devices that are compatible with HD standards.

The specific capabilities of HDMI vary by version (see below for more details), but in general they are quite impressive — even in the earliest (current today) HDMI v.1.4, the maximum resolution is 4K, and in newer standards it reaches 10K. So in motherboards, the quality of the video transmitted through such an output is often limited not by the interface capabilities, but by the graphics performance of the system.

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 number of USB 2.0 connectors installed on the back of the motherboard.

Recall that USB is the most popular modern connector for connecting various external peripherals — from keyboards and mice to specialized equipment. And USB 2.0 is the oldest version of this interface that is relevant today; it is noticeably inferior to the newer USB 3.2 both in terms of speed (up to 480 Mbps), and in terms of power supply and additional functionality. On the other hand, even such characteristics are often enough for undemanding peripherals (like the same keyboards / mice); and devices of newer versions can be connected to the connectors of this standard — there would be enough power supply. So this version of USB is still found in modern motherboards, although there are fewer and fewer new models with USB 2.0 connectors.

Note that in addition to the connectors on the rear panel, connectors on the board itself (more precisely, ports on the PC case connected to such connectors) can also provide a USB connection. See below for more on this.
