Comparison Asus PRIME Z270-P vs Asus PRIME Z270-K

The presence of its own LED backlight on the motherboard. This feature does not affect the functionality of the "motherboard", but gives it an unusual appearance. Therefore, it hardly makes sense for an ordinary user to specifically look for such a model (a motherboard without backlighting is enough for him), but for modding lovers, backlighting can be very useful.

LED backlighting can take the form of individual lights or LED strips, come in different colours (sometimes with a choice of colours) and support additional effects — flashing, flickering, synchronization with other components (see "Lightning synchronization"), etc. Specific features depend on the motherboard model.

Number of SATA 3 ports on the motherboard.

SATA is now the standard interface for connecting internal drives (mainly HDDs) and optical drives. One device is connected to one such connector, so the number of SATA ports corresponds to the number of internal drives / drives that can be connected to the motherboard through such an interface. A large number ( 6 SATA ports and more) is necessary in case of active use of several hard drives and other peripherals. For domestic use, 4 is enough. SATA 3, as the name suggests, is the third version of this interface, operating at a total speed of about 6 Gbps; the useful speed, taking into account the redundancy of the transmitted data, is about 4.8 Mbps (600 MB / s) — that is, twice as much as in SATA 2.

Note that different SATA standards are quite compatible with each other in both directions: older drives can be connected to newer ports, and vice versa. The only thing is that the data transfer rate will be limited by the capabilities of the slower version, and in some cases it may be necessary to reconfigure the drives with hardware (switches, jumpers) or software. It is also worth saying that SATA 3 is the newest and most advanced variation of SATA today, but the capabilities of this standard are not enough to unlock the full potential of high-speed SSDs. Therefore, SATA 3 is mainly used for hard drives and low-cost SSDs, faster drives are conn...ected to specially designed connectors like M.2 or U.2 (see below).

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 PCI slots provided in the design of the motherboard.

These slots are used for expansion cards. At the same time, technically, this interface is considered obsolete — in particular, it is noticeably inferior to the newer PCI-E in terms of data transfer speed (up to 533 MB / s). Nevertheless, for some types of components (for example, sound cards), such features are quite enough; and the use of PCI allows you to leave free PCI-E slots that may be needed for more demanding peripherals. So even nowadays, both motherboards with PCI slots and components with such a connection can still be found on the market.

The motherboard has its own D-Sub (VGA) 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 VGA specifically, it is an analogue standard originally created for CRT monitors. It does not differ in image quality, is practically not suitable for resolutions above 1280x1024 and does not provide sound transmission, and therefore is generally considered obsolete. However, this type of input continues to be used in some monitors, TVs, projectors, etc.; so among motherboards you can find models with such outputs.

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 native USB 3.2 gen1 connectors provided on the back of the motherboard. In this case, traditional, full-size USB A ports are meant.

USB 3.2 gen1(formerly known as USB 3.1 gen1 and USB 3.0) is a direct successor and development of the USB 2.0 interface. The main differences are a 10-fold increase in the maximum data transfer rate — 4.8 Gbps — as well as higher power supply, which is important when connecting several devices to one port through a splitter (hub). At the same time, peripherals of other versions can be connected to this connector.

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). There are boards on the market that have more than 4 USB 3.2 gen1 ports on the back panel. 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 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 USB-C version 3.2 gen1 connectors provided on the back of the motherboard.

USB-C is a relatively new type of connector used in both portable and desktop PCs. It has a small size and a convenient double-sided design, thanks to which the plug can be inserted into the connector in either direction. And version 3.2 gen1 connectivity (formerly known as USB 3.1 gen1 and USB 3.0) allows you to work at speeds up to 4.8 Gbps. In addition, when using this version with a USB-C connector, this port can implement USB Power Delivery technology, which allows you to supply power up to 100 W to external devices (although not every USB-C 3.2 gen1 port on motherboards supports Power Delivery).

As for the quantity, modern motherboards almost never have more than one USB-C 3.2 gen1 connector. This is related to two things. Firstly, not many peripherals with a USB-C plug are available for desktop PCs — full-sized USB A are still more popular; secondly, many manufacturers prefer USB-C ports of more advanced versions — 3.2 gen2 and 3.2 gen2x2 (see below). Also 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.
