Comparison Gigabyte B450 AORUS PRO rev. 1.0 vs Gigabyte X470 AORUS ULTRA GAMING

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 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.

Electrical (logical) interfaces implemented through physical M.2 connectors on the motherboard.

See above for more details on such connectors. Here we note that they can work with two types of interfaces:

• SATA is a standard originally created for hard drives. M.2 usually supports the newest version, SATA 3; however, even it is noticeably inferior to PCI-E in terms of speed (600 MB / s) and functionality (only drives);
• PCI-E is the most common modern interface for connecting internal peripherals (otherwise NVMe). Suitable for both expansion cards (such as wireless adapters) and drives, while PCI-E speeds allow you to fully realize the potential of modern SSDs. The maximum communication speed depends on the version of this interface and on the number of lines. In modern M.2 connectors, you can find PCI-E versions 3.0 and 4.0, with speeds of about 1 GB / s and 2 GB / s per lane, respectively; and the number of lanes can be 1, 2 or 4 (PCI-E 1x, 2x and 4x respectively)

Specifically, the M.2 interface in the characteristics of motherboards is indicated by the number of connectors themselves and by the type of interfaces provided for in each of them. For example, the entry "3xSATA / PCI-E 4x" means three connectors that can work both in SATA format and in PCI-E 4x format; and the designation "1xSATA / PCI-E 4x, 1xPCI-E 2x" means two connectors, one of which works as SATA or PCI-E 4x, and the second — only as PCI-E 2x.

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.

Operating modes of PCI-E 16x slots supported by the motherboard.

For more information about this interface, see above, and information about the modes is indicated if there are several PCI-E 16x slots on the board. This data specifies at what speed these slots can operate when expansion cards are connected to them at the same time, how many lines each of them can use. The fact is that the total number of PCI-Express lanes on any motherboard is limited, and they are usually not enough for the simultaneous operation of all 16-channel slots at full capacity. Accordingly, when working simultaneously, the speed inevitably has to be limited: for example, recording 16x / 4x / 4x means that the motherboard has three 16-channel slots, but if three video cards are connected to them at once, then the second and third slots will be able to give speed only to PCI-E 4x level. Accordingly, for a different number of slots and the number of digits will be appropriate. There are also boards with several modes — for example, 16x/0x/4 and 8x/8x/4x (0x means that the slot becomes inoperable altogether).

You have to pay attention to this parameter mainly when installing several video cards at the same time: in some cases (for example, when using SLI technology), for correct operation of video adapters, they must be connected to slots at the same speed.

Motherboard support for NVIDIA SLI technology.

This technology allows you to connect several individual NVIDIA graphics cards to your 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, SLI 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 AMD is called Crossfire (see above). The main difference between these technologies is that SLI is more demanding on compatibility: it only works on video cards with the same GPU models (although other parameters — the manufacturer, the amount and frequency of video memory, etc. — may be different). In addition, video adapters in an SLI bundle must be connected with a cable or a bridge (the only exceptions are some low-cost models); and support for this technology is somewhat more expensive than in the case of Crossfire, so it is less common in motherboards (and mostly together wi...th the solution from AMD).

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 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.

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.
