Comparison MSI MPG X570 GAMING EDGE WIFI vs Gigabyte X570 AORUS ELITE

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.

Synchronization technology provided in the board with LED backlight (see above).

Synchronization itself allows you to "match" the backlight of the motherboard with the backlight of other system components — cases, video cards, keyboards, mice, etc. Thanks to this matching, all components can change colour synchronously, turn on / off at the same time, etc. Specific features the operation of such backlighting depends on the synchronization technology used, and, usually, each manufacturer has its own (Mystic Light Sync for MSI, RGB Fusion for Gigabyte, etc.). The compatibility of the components also depends on this: they must all support the same technology. So the easiest way to achieve backlight compatibility is to collect components from the same manufacturer.

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.

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.

Number of PCI-E (PCI-Express) 16x slots installed on the motherboard.

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. 16 lanes is the largest number found in modern PCI Express slots and cards (more is technically possible, but the connectors would be too bulky). Accordingly, these slots are the fastest: they have a data transfer rate of 16 GB / s for PCI-E 3.0 and 32 GB / s for version 4.0 (for more information about the versions, see "PCI Express Support").

Separately, we note that it is PCI-E 16x that is considered the optimal connector for connecting video cards. However, when choosing a motherboard with several such slots, it is worth considering the PCI-E modes supported by it (see below). In addition, we recall that the PCI Express interface allows you to connect boards with a smaller number of lines to connectors with numerous lines. Thus, PCI-E 16x will fit any PCI Express card.

It is also worth mentioning that in the design of modern "motherboards" there are slots of increased sizes — in particular, PCI-E 4x, corresponding in size to PCI-E 16x. However, the type of PCI-E slots in our catalog is indicated by the actual throughput; so only connectors that support 16x speed are considered as PCI-E 16x.

Motherboard support for AMD's Crossfire technology.

This technology allows you to connect several separate AMD graphics cards to a PC at once and combine their computing power, respectively increasing the system's graphics performance in specific tasks. Accordingly, this feature means that the "motherboard" is equipped with at least two slots for video cards — PCI-E 16x; in general, Crossfire allows up to 4 separate adapters to be connected.

Such functionality is especially important for demanding games and "heavy" tasks like 3D rendering. However, note that in order to use several video cards, this possibility must also be provided in the application running on the computer. So in some cases, one powerful video adapter is more preferable than several relatively simple ones with the same total amount of VRAM.

A similar technology from NVIDIA is called SLI (see below). Crossfire differs from it mainly in three points: the ability to combine video adapters with different models of graphics processors (the main thing is that they are built on the same architecture), no need for additional cables or bridges (video cards interact directly via the PCI-E bus) and somewhat lower cost (allowing the use of this technology even in low-cost "motherboards"). Thanks to the latter, almost all motherboards with SLI also support Crossfire, but not vice versa.

The number of USB-C 3.2 gen2 connectors provided in the motherboard.

USB-C connectors (all versions) are used to connect to the "motherboard" USB-C 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 USB-C chassis connectors that can be used with it.

Recall that USB-C is a relatively new type of USB connector, it is distinguished by its small size and double-sided design; such connectors have their own technical features, so separate connectors must be provided for them. Specifically, the USB 3.2 gen2 version (formerly known as USB 3.1 gen2 and USB 3.1) operates at speeds up to 10 Gbps and allows you to implement USB Power Delivery technology, thanks to which the power supply of USB peripherals can reach 100 W per port. However, the presence of Power Delivery in specific motherboards (and even in specific connectors on the same board) should be specified separately.

HDMI connector version (see above) installed in the motherboard.

— v.1.4. The earliest of the standards found nowadays, which appeared back in 2009. Supports resolutions up to 4096x2160 inclusive and allows you to play Full HD video with a frame rate of up to 120 fps — this is enough even for 3D playback.

— v.1.4b. A modified version of v.1.4 described above, which introduced a number of minor updates and improvements — in particular, support for two additional 3D formats.

— v.2.0. Also known as HDMI UHD, this version introduced full 4K support, with frame rates up to 60 fps, as well as the ability to work with 21:9 ultra-widescreen video. In addition, thanks to the increased bandwidth, the number of simultaneously reproduced audio channels has grown to 32, and audio streams to 4. And in the v.2.0a improvement, HDR support has also been added to all this.

— v.2.1. Another name is HDMI Ultra High Speed. Compared to the previous version, the interface bandwidth has really increased significantly — it is enough to transmit video at resolutions up to 10K at 120 frames per second, as well as to work with the extended BT.2020 colour space (the latter may be useful for some professional tasks). HDMI Ultra High Speed cables are required to use the full capabilities of HDMI v2.1, but older standard features are available with regular cables.

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.
