Comparison MSI MPG X870E EDGE TI WIFI vs MSI MPG B850 EDGE TI WIFI

The heat pipe is a hermetically sealed structure containing a low-boiling liquid. When one end of the tube is heated, this liquid evaporates and condenses at the other end, thus removing heat from the heating source and transferring it to the radiator. Such devices are simple and at the same time effective, so they can be easily used as an addition to radiators.

The chipset model installed in the motherboard. AMD's current chipset models are B450, A520, B550, X570, A620, B650, B650E, X670, X670E, B840, B850, X870, X870E. 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, H810, B860, Z890.

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, memory, 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.

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 3.2 gen2 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 gen2 connectivity (formerly known as USB 3.1 gen2 and USB 3.1) is capable of operating at speeds up to 10 Gbps and supports USB Power Delivery technology, which allows you to supply power to external devices up to 100 watts. However, the presence of Power Delivery should be specified separately, this function is not mandatory.

As for the quantity, most often there is only one such port, only a few motherboard models have two USB-C 3.2 gen2 connectors. This is due to the fact that not so many peripherals with a USB-C plug are produced for desktop PCs — full-sized USB A are still more popular. Also note that in addition to the connectors on the rear panel, connectors on the board itself can also provide a USB connection (more precisely, ports on the case connected to such connectors). See below for more on this.

The number of USB C 3.2 gen3x2 (USB4) connectors provided on the back panel of the motherboard.

The interface bandwidth reaches an impressive rate of up to 40 Gbps (in dual-band mode). As before, 3.2 gen3x2 version supports USB Power Delivery technology, which allows to supply power to external devices up to 100 watts. The interface is also backward compatible with previous USB specifications.

Support for Alternate Mode via the USB-C connector(s) provided on the back of the motherboard.

This feature means that not only the USB interface can be implemented through such a connector, but also other types of connection (in particular , video transmission via USB-C). The specific set of supported interfaces (as well as the number of ports with Alternate Mode) should be specified separately. The most typical example is Thunderbolt v3 (see “Thunderbolt interface”): this version, by definition, works through the USB-C hardware connector. The Thunderbolt specification also includes support for DisplayPort, but this video output can be implemented through Alternate Mode and independently, without Thunderbolt functionality. Also, the list of interfaces that can be supported by such ports includes HDMI, including the "mobile" version of MHL; the latter, however, is extremely rare in desktop motherboards.
