Comparison ASRock H110M-DGS R3.0 vs Asus M5A78L-M LX3

The type of socket (socket for CPU) that the motherboard is equipped with. Different processor models correspond to different types of sockets, and before buying a motherboard, you should separately check whether the type of socket on it matches the type of socket for the desired processor.

Accordingly, motherboard manufacturers present platforms for current processors: Intel S1150, S1155, S1156, S1356, S1366, S2011, S2066, S1151, S1151 Coffee Lake, S3647, S1200, S1700.

And AMD: AM4, AM5, TR4 / TRX4.

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).

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 chipset model installed in the motherboard. AMD's current chipset models are B450, A520, B550, X570, X570S, A620, B650, B650E, X670 and X670E. For Intel, in turn, the list of chipsets looks like this: X299, H410, B460, H470, Z490, H510, B560, H570, Z590, H610, B660, H670, Z690, B760, Z790.

A chipset is a set of chips on the motherboard through which the individual components of the system interact directly: the processor, RAM, drives, audio and video adapters, network controllers, etc. Technically, such a set consists of two parts — the north and south bridges. The key element is the northbridge, it connects the processor, mem...ory, graphics card and the southbridge (together with the devices it controls). Therefore, it is often the name of the north bridge that is indicated as the chipset model, and the south bridge model is specified separately (see below); it is this scheme that is used in traditional layout motherboards, where bridges are made in the form of separate microcircuits. There are also solutions where both bridges are combined in one chip; for them, the name of the entire chipset can be indicated.

Anyway, knowing the chipset model, you can find various additional data on it — from general reviews to special instructions. An ordinary user, usually, does not need such information, but it can be useful for various professional tasks.

Model of the south bridge installed in the motherboard.

This component of the "motherboard" is one of the constituent parts of the chipset. See above for details on the chipset; here we note that the south bridge is responsible for the interaction of the motherboard with peripheral devices: expansion cards (sound, network), drives, external USB peripherals, etc. Knowing the name of this module, if necessary, you can easily find detailed information about its characteristics and capabilities. An ordinary user, usually, does not need such information, but it can be useful for various professional tasks.

The presence of UEFI BIOS firmware on the motherboard.

Such firmware is usually combined with one of the classic "bios" (see BIOS). In fact, it is an additional add-on that expands the BIOS and makes it more convenient to manage. In some ways, UEFI approaches a full-fledged operating system: it has a convenient and understandable graphical interface even for a non-specialist, supports mouse control, is equipped with an extensive set of tools, and in some versions there is even the ability to access the Internet. In addition, this firmware takes into account all the features of modern computer hardware — including those that have appeared recently and are not covered in earlier, traditional BIOSes.

The number of slots for DDR3 memory sticks provided in the motherboard.

DDR3 is the third generation of RAM with the so-called double data transfer. Some time ago, this standard was the most popular in computer technology, but now it is increasingly losing ground to the newer and more advanced DDR4. However, DDR3 boards are still on the market; they can have 2, 4, or even 6 or more slots for such memory.

The number of slots for DDR4 memory sticks provided in the motherboard.

DDR4 is a further (after the third version) development of the DDR standard, released in 2014. Improvements compared to DDR3 are traditional — an increase in operating speed and a decrease in power consumption; The volume of one module can be from 2 to 128 GB. It is this RAM standard that most modern motherboards are designed for; the number of slots for DDR4 is usually 2 or 4, less often — 6 or more.

The maximum RAM clock speed supported by the motherboard. The actual clock frequency of the installed RAM modules should not exceed this indicator — otherwise, malfunctions are possible, and the capabilities of the “RAM” cannot be used to the fullest.

For modern PCs, a RAM frequency of 1500 – 2000 MHz or less is considered very low, 2000 – 2500 MHz is modest, 2500 – 3000 MHz is average, 3000 – 3500 MHz is above average, and the most advanced boards can support frequencies of 3500 – 4000 MHz and even more than 4000 MHz.
