Comparison Gigabyte X870E AORUS PRO vs Gigabyte X870E AORUS ELITE WIFI7

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.

The motherboard has its own Bluetooth module, which eliminates the need to purchase such an adapter separately. Bluetooth technology is used for direct wireless connection of a computer with other devices — mobile phones, players, tablets, laptops, wireless headphones, etc.; connectivity options include both file sharing and external device control. The Bluetooth connection range is up to 10 m (in later standards — up to 100 m), while the devices do not have to be in the line of sight. Different versions of Bluetooth (at the end of 2021, the latest of which is Bluetooth v 5) are mutually compatible in terms of basic functionality and have all sorts of differences.

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.

The number of native USB 3.2 gen2 connectors provided on the back of the motherboard. In this case, we mean traditional, full-size USB A ports.

USB 3.2 gen2(formerly known as USB 3.1 gen2 and simply USB 3.1) is the evolution of USB 3.2 after version 3.2 gen1 (see above). This standard provides connection speeds up to 10 Gbps, and to power external devices in such connectors, USB Power Delivery technology (see below) can be provided, which allows you to output up to 100 W per device (however, Power Delivery support is not mandatory, its presence should be specified separately). Traditionally for the USB standard, this interface is backwards compatible with previous versions — in other words, you can easily connect a device supporting USB 2.0 or 3.2 gen1 to this port (unless the speed will be limited by the capabilities of a slower version).

The more connectors provided in the design, the more peripheral devices can be connected to the motherboard without the use of additional equipment (USB splitters). In some models of motherboards, the number of ports of this type is 5 or even more. At the same time, we note that in addition to the connectors on the rear panel, connectors on the board itself (more precisely, ports on the case connected to such connectors) can also provide a USB connection. See below for more on this.

The number of connectors for powering coolers and fans provided in the motherboard. A processor cooler is usually connected to such a connector, and fans of other system components — video cards, cases, etc. can also be powered from the "motherboard"; sometimes it is more convenient than pulling power directly from the PSU (at least you can reduce the number of wires in the case). Many modern boards are equipped with 4 or more connectors of this type.

A connector responsible for connecting additional coolers for the benefit of better cooling of components inside the system unit. Most often it is located on the edges of the motherboard — closer to the front side and the ceiling of the "system unit". It is made according to the four-contact scheme.
