Comparison Asus ROG STRIX B760-F GAMING WIFI vs Asus ROG STRIX B660-F GAMING WIFI

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.

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.

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.

The version of the M.2 interface determines both the maximum data transfer rate and the supported devices that can be connected via physical M.2 connectors (see the corresponding paragraph).

The version of the M.2 interface in the specifications of motherboards is usually indicated by the number of connectors themselves and by the PCI-E revision provided for in each of them. For example, the entry “3x4.0” means three connectors capable of supporting PCI-E 4.0; and the designation “2x5.0, 1x4.0” means a trio of connectors, two of which support PCI-E 4.0, and another one supports PCI-E 5.0.

Specialized TPM connector for connecting the encryption module.

TPM (Trusted Platform Module) allows you to encrypt the data stored on your computer using a unique key that is practically unbreakable (it is extremely difficult to do this). The keys are stored in the module itself and are not accessible from the outside, and data can be protected in such a way that their normal decryption is possible only on the same computer where they were encrypted (and with the same software). Thus, if information is illegally copied, an attacker will not be able to access it, even if the original TPM module with encryption keys is stolen: TPM will recognize the system change and will not allow decryption.

Technically, encryption modules can be built directly into motherboards, but it is still more justified to make them separate devices: it is more convenient for the user to purchase a TPM if necessary, and not overpay for an initially built-in function that may not be needed. Because of this, there are motherboards without a TPM connector at all.

5-pin connector that allows you to connect an expansion card. It, in turn, provides high-speed data exchange (up to 40 Gbps), the ability to connect external monitors, high-speed charging of compatible devices, etc.

Wi-Fi version (standard) supported by the motherboard Wi-Fi module. The main function of such modules, regardless of version, is Internet access via wireless routers; however, Wi-Fi can also be used to communicate directly with other devices—for example, to transfer content from a digital camera or control it remotely.

Nowadays you can find support for different Wi-Fi standards (up to Wi-Fi 6, Wi-Fi 6E, Wi-Fi 7). The maximum connection speed primarily depends on this nuance. At the same time, different versions also differ in the ranges used; and they are compatible with each other if they coincide in the ranges used. However, wireless modules of modern motherboards often support not only the Wi-Fi standard specified in the specifications, but also earlier ones; It doesn’t hurt to clarify this point separately, but in most cases there are no compatibility problems. However, to use all the features of a particular version, it must be supported by both devices - both the motherboard and the external device.

The list of major versions looks like this:

- Wi-Fi 3 (802.11g). The oldest standard that is relevant today, in its pure form, is found only in frankly outdated boards. Operates at speeds up to 54 Mbps in the 2.4 GHz band.
— Wi-fi 4 (802.11n). Quite a popular standard, which has only recently begun to give w...ay to more advanced options. Supports both the 2.4 GHz band and the more advanced 5 GHz band, and the maximum data transfer rate is 150 Mbps per channel (up to 600 Mbps with 4 antennas).
— Wi-Fi 5 (802.11ac). Works only on 5 GHz. Initially, the maximum theoretical data transfer rate was 1300 Mbit/s, but since 2016 the 802.11ac Wave 2 standard has been used, where this figure has been increased to 2.34 Gbit/s.
- Wi-Fi 6 (802.11ax). It initially operates on two bands - 2.4 GHz and 5 GHz - but the specification of this standard provides for the possibility of using any operating band between 1 GHz and 7 GHz (as such bands become available). The nominal data transfer speed has increased by only a third compared to Wi-Fi 5, but a number of improvements that increase communication efficiency allow for a significant increase in actual speed - in theory, up to 10 Gbps and even higher.
- Wi-Fi 6E (802.11ax). An improved branch of the Wi-Fi 6 standard with data transfer speeds up to 10 Gbps. The Wi-Fi 6E standard is technically called 802.11ax. But unlike basic Wi-Fi 6, which is named similarly, it provides for operation in the unused 6 GHz band. In total, the standard uses 14 different frequency bands, offering high throughput with many active connections.
— Wi-Fi 7 (802.11be). The technology, like the previous Wi-Fi 6E, is capable of operating in three frequency ranges: 2.4 GHz, 5 GHz and 6 GHz. At the same time, the maximum bandwidth in Wi-Fi 7 was increased from 160 MHz to 320 MHz - the wider the channel, the more data it can transmit. The IEEE 802.11be standard uses 4096-QAM modulation, which also allows more symbols to be accommodated in a data transmission unit. From Wi-Fi 7 you can squeeze out a maximum theoretical information exchange rate of up to 46 Gbps. In the context of using wireless connections for streaming and video games, the implemented MLO (Multi-Link Operation) development seems very interesting. With its help, you can aggregate several channels in different ranges, which significantly reduces delays in data transmission and ensures low and stable ping. And Multi-RU (Multiple Resource Unit) technology is designed to minimize communication delays when there are many connected client devices.

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.

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).
