Comparison Asus Vivobook 16X OLED K3604ZA [K3604ZA-MB108] vs Asus Vivobook 16 OLED X1605ZA [X1605ZA-MB315]

The result shown by the laptop processor in the Passmark CPU Mark test.

Passmark CPU Mark is a comprehensive test that is more detailed and reliable than the popular 3DMark06 (see above). It checks not only the gaming capabilities of the CPU, but also its performance in other modes, based on which it displays the overall score; this score can be used to fairly reliably evaluate the processor as a whole (the more points, the higher the performance).

The connection interface used by the M.2 SSD installed in the laptop (see "Drive type").

One of the features of the M.2 connector and drives for it is that they can use two different connection interfaces: PCI-E (in one form or another) or SATA. We emphasize that this paragraph indicates the data of the SSD module; the connector itself may provide other interface options, including more advanced ones — see "M.2 connector interface" (for example, a drive with a PCI-E 3.0 2x connection can be placed in a connector that also supports the faster PCI-E 4.0 4x). However, anyway, the connection connector usually allows you to realize all the features of the installed drive; so this item allows you to quite reliably evaluate the capabilities of the standard M.2 module.

As for specific interfaces, nowadays you can mainly find the following options:

— SATA 3. The SATA interface was originally designed for traditional hard drives. The third version of this interface is the latest; it provides data transfer rates up to 600 Mbps. This is significantly less than PCI-E, and in general, very little by the standards of SSD drives. Therefore, M.2 connection using SATA is typical mainly for low-cost entry-level modules. However, even these media are generally faster than most HDDs.

— PCI-E. Universal interface for connecting internal peripherals. Provides generally faster speeds than SATA, making it better suited for SSD modules: theoretically, PC...I-E allows you to realize the full potential of SSDs, even the fastest. In fact, the supported data transfer rate may be different — depending on the version of the interface and the number of lines (data transmission channels). Here are the options most relevant for modern laptops:

• PCI-E 3.0 2x. Connection using 2 lanes PCI-E version 3.0. This version provides speeds of about 1 GB/s per line; respectively, two lines give a maximum of just under 2 GB / s.
• PCI-E 3.0 4x. Connection using 4 lanes PCI-E version 3.0. Provides a maximum speed of about 4 GB / s.
• PCI-E 4.0 4x. Connection using 4 lanes PCI-E version 4.0. In this version, the throughput, compared to PCI-E 3.0, has been doubled — thus, 4 lines give a maximum speed of about 8 MB / s.

Note that in the case of M.2 connectors, different PCI-E variations are usually quite compatible with each other — except that the connection speed when working with a "non-native" connector will be limited by the capabilities of the slowest component. For example, when connecting a PCI-E 3.0 4x SSD module to a PCI-E 3.0 2x slot, this speed will correspond to the capabilities of the connector, and when connected to PCI-E 4.0 4x, to the capabilities of the drive.

The interface of the main M.2 connector provided in the laptop.

In this case, the main slot is considered to be the one in which the SSD M.2 drive is installed (see "Drive type"). The interface of the drive itself is indicated separately (see above), and the interface of the connector is specified if the connector supports a more advanced type of connection than the device installed in it. An example is the following situation: the device itself works according to the SATA or PCI-E 3.0 2x standard (see "M.2 drive interface" above), and the connector on the board is capable of working with the PCI-E 3.0 4x interface.

Such information will be useful, first of all, for evaluating the possibilities for upgrading a laptop (with replacing a standard SSD module with a faster one). Nowadays, in this paragraph, you can mainly find the following options:

— PCI-E 3.0 2x. In fact, the most modest PCI-E standard found in M.2 ports of modern laptops: connection using 2 lanes of PCI-E version 3.0. This version provides speeds of about 1 GB/s per line; respectively, two lines give a maximum of just under 2 GB / s.

— PCI-E 3.0 4x. Connection using 4 lanes PCI-E version 3.0. Provides a maximum speed of about 4 GB / s.

— PCI-E 4.0 4x. Connection using 4 lanes PCI-E version 4.0. In this version, the bandwidth, compared to PCI-E 3.0, has been doubled — thus, 4 lines give a maximum speed of about 8 GB / s.

— PCI-E. Connection...via PCI-E, for which the manufacturer did not specify the details (version and number of lines).

Recall that in the case of M.2 connectors, different PCI-E options are quite compatible with each other — except that the speed will be limited by the capabilities of a slower component. In fact, this means that, for example, in an M.2 connector with a PCI-E 3.0 4x interface, it is quite possible to connect a drive for PCI-E 3.0 2x or PCI-E 4.0 4x; in the first case, the speed will be limited by the capabilities of the drive, in the second, by the capabilities of the connector.

Wi-Fi standards supported by the laptop.

In modern laptops, most often there are wireless communication modules that support Wi-Fi 5 (802.11ac), Wi-Fi 6 (802.11ax), Wi-Fi 6E (802.11ax), Wi-Fi 7 (802.11be). Earlier standards appear infrequently; First of all, this is Wi-Fi 4 (802.11n), which ensures compatibility of the laptop with legacy wireless equipment. Here are the features of each of these standards:

- Wi-Fi 5 (802.11ac). Standard introduced in 2013. It operates exclusively on the 5 GHz frequency, which is why it is only compatible with Wi-Fi 4 and newer versions. Provides a theoretical maximum speed of up to 1 Gbps with a single-channel connection and up to 6 Gbps with multiple channels in MIMO format, while consuming significantly less power than its predecessor.

- Wi-Fi 6 (802.11ax). A standard developed as a direct development and improvement of Wi-Fi 5. A priori, it operates at standard frequencies of 2.4 GHz and 5 GHz (including equipment of earlier standards), but if necessary, it can connect additional bands in the range from 1 to 7 GHz. The maximum data transfer speed has increased to 10 Gbps, but the main advantage of Wi-Fi 6 is not even this, but the further optimization of the simultaneous operation of several devices on the same channel. Wi-Fi 6 provides a minimal drop in speed under conditions...of high channel load.

- Wi-Fi 6E (802.11ax). 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 an additional unused 6 GHz band. In total, the standard uses 14 different frequency bands, offering high throughput in the most crowded places with many active connections. And it's backwards compatible with previous versions of Wi-Fi.

— 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 speed 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.

Technology for direct wireless communication between various devices, in particular for connecting speakers, headphones, for transferring files, etc. Version plays a key role in Bluettoth's abilities. In modern realities, Bluetooth wireless protocols below revision 4 are no longer relevant. More about them:

— Bluetooth v 4.0. A fundamental update (after version 3.0), which introduced another data transfer format — Bluetooth Low Energy (LE). Bluetooth LE allows you to significantly save energy with such a connection.

— Bluetooth v 4.1. Development and improvement of Bluetooth 4.0. One of the key improvements was the optimization of collaboration with 4G LTE communication modules — so that Bluetooth and LTE do not interfere with each other. In addition, this version has the ability to simultaneously use a Bluetooth device in several roles.

— Bluetooth v 4.2. This version did not introduce fundamental updates, however, it received a number of improvements regarding reliability and noise immunity, as well as improved compatibility with the Internet of Things.

— Bluetooth v 5.0. Version introduced in 2016. The key innovations were the further expansion of the possibilities associated with the Internet of Things. In particular, in the Bluetooth Low Energy protocol (see above), it became possible to double the data transfer rate (up to 2 Mbit / s) at the cost of reducing the range, as well as quadruple the range at the cost of redu...cing the speed; in addition, a number of improvements have been introduced regarding the simultaneous work with numerous connected devices.

— Bluetooth v 5.1. Update of the version described above v 5.0. In addition to general improvements in the quality and reliability of communication, this update has implemented such an interesting feature as determining the direction from which the Bluetooth signal is coming. This makes it possible to determine the location of connected devices with an accuracy of up to a centimeter, which can be useful, for example, when searching for wireless headphones.

— Bluetooth v 5.2. The main innovations in this release are a number of security improvements, additional power optimization in LE mode, and a new audio signal format for synchronizing parallel playback on multiple devices.

The presence in the laptop of at least one USB-C connector with support for Power Delivery technology.

Recall that USB-C can be used to connect USB 3.2 (gen1 or gen2), USB4 and Thunderbolt (v3 and v4). See above for details on all of these interfaces. And support for Power Delivery at least means that such a connector is capable of delivering increased power to the connected device — up to 100 watts. Thanks to this, even rather high consumption peripherals can work without a separate power source. In addition, if a gadget that supports Power Delivery (or fast charging technology compatible with it) is being charged from USB-C, the charging process is significantly accelerated. At the same time, one of the features of this technology is that it allows the laptop to coordinate the output power with the connected device — so that it is sufficient and at the same time does not cause overloads.

Also note that USB-C in some models is used to charge the battery in the laptop itself. In such cases, Power Delivery helps to reduce the time of such a charge — of course, with a compatible charger. However, the availability of such a possibility should be clarified separately.

The presence of a fast charging function in the laptop. Also, the notes to this paragraph may specify the specific possibilities of such charging — for example, "50% in 40 minutes."

The general features of this function are obvious from the name — it significantly reduces the battery charging time compared to the standard procedure. This requires specialized chargers, but such chargers are often supplied with a laptop. And finding a third-party charger is not a problem — just make sure that it supports the same fast charging technology as the device itself (or at least one of the compatible ones).

Detailed information about different fast charging technologies can be found in special sources. Here it is worth touching separately on data on partial charging, which can be given in the notes — like the “50% in 40 minutes” mentioned above. When evaluating these data, note that the battery charging rate is uneven: it is highest at the first percent of the charge, then the process gradually slows down. Two practical implications follow from this. Firstly, information about the partial charge rate is relevant only if the battery is charged from scratch. In our example, this means that from 0 to 50% the battery will really charge in 40 minutes, but for charging, say, from 20 to 70%, it will take a little more time. The second caveat is that the time for a full charge will not be directly proportional to the specified partial c...harge time: again, using our example, "50% in 40 minutes" does not mean "100% in 80 minutes" — the latter will take longer. In fact, such nuances are most often unprincipled, but they can be critical in cases where the charging time is very limited.

The maximum power of the power supply in watts from which the laptop is supplied with power. Note that in this case the maximum power level is indicated, and this is achieved only when performing the most energy-intensive tasks, such as playing games, video rendering, etc. The rest of the time the power supply consumes an order of magnitude less power. This parameter may be useful when calculating the load when connecting a laptop computer to an uninterruptible power supply (UPS) or other means of autonomous power supply. When choosing a power supply yourself, you need to purchase it with parameters similar to the original unit or with a small power reserve on the larger side.

The main material from which the laptop case is made.

Modern laptops can use materials such as plastic (mostly matte plastic), aluminium, magnesium alloy, carbon fibre, and even glass. These materials are found both individually and in various combinations; the most common case is aluminium with plastic, but more specific combinations exist. Here is a more detailed description of the most relevant options:

— Matte plastic. Plastic with a matte (not shiny) surface is one of the most popular materials for laptop cases today. This is due, on the one hand, to low cost, on the other hand, to good practical characteristics. So, such a case can be given any colour and any pattern can be applied to it. The strength of plastic is lower than that of metals or carbon fibre, but it is usually more than enough for everyday use. And the light weight is not only an advantage in itself — it also allows you to make the walls of the case thick enough; as a result, plastic cases are often found even among shockproof models. As for the matte surface specifically, it itself looks dimmer than the glossy one, but it is not so prone to pollution. In particular, fingerprints and palm marks are practically invisible on it; and the scratches that plastic is subject to do not stand out as clearly as on gloss. A bright a...ppearance of the device can be given due to other design solutions — for example, keyboard backlighting (see above).

— Aluminium. From a practical point of view, aluminium alloys combine lightness and high strength; in addition, the metal conducts heat well, which improves the efficiency of cooling systems. Most of these cases have a characteristic grey tint, which looks quite stylish even without special coloring; and in some models, aluminium can additionally be given one or another colour. The main disadvantage of this material is a higher cost than plastic; as a result, it is used mainly in devices of the middle and top classes.

— Magnesium alloy. Such alloys surpass even the aluminium described above in strength, while they have a relatively small weight and excellent heat dissipation. However, this material is not cheap. Therefore, it is used quite rarely, and in its pure form — even less often; combinations of magnesium alloy with other, usually more affordable materials are more popular (see below for more details).

– Aluminium / plastic. Combination of plastic and aluminium elements in one housing. Usually, parts subjected to the greatest loads are made of metal, and the rest of the structure is made of plastic. These materials are described in more detail above, and their combination allows you to combine the advantages and partially compensate for the disadvantages. In particular, such combined cases are cheaper than all-metal ones and at the same time more reliable than plastic ones; in addition, they are easier to give a bright appearance than products made of aluminium or magnesium. This combination can be found even among relatively inexpensive laptops, although most metal-plastic models still belong to more advanced categories.

— Carbon fibre. Also known as "carbon". Usually, it is used in the form of a composite — a carbon fibre base is complemented by a plastic filler. Carbon belongs to the premium class materials: it is characterized by very high strength and at the same time low weight. A dark colour and a characteristic pattern on the surface give such cases a stylish appearance. However, carbon fibre is very expensive — much more expensive than even aluminium and magnesium, not to mention plastic. Therefore, such cases are a characteristic feature of top segment laptops. Also note that carbon does not tolerate point impacts; thus, and also to reduce cost, it is often used in combination with metals (see below for more details).

– Aluminium / magnesium alloy. Cases combining two types of metals. Usually, the main part of such a case is made of aluminium, and the individual, most important parts are made of magnesium. This allows some cost and weight savings compared to pure magnesium alloy cases, while at the same time providing greater strength and reliability than aluminium. A rarer and more specific variant is the 2-in-1 devices (see "Type"), where the top half is made of lighter aluminium (for easy portability) and the bottom half is made of durable magnesium.

– Aluminium / carbon fibre. Cases that combine elements of aluminium and carbon fibre. The specific set of parts from both materials can be different, but the upper side of the lower half of the device (where the touchpad and keyboard are) are most often made of carbon fibre. Such a surface not only looks good, but often also turns out to be more pleasant to the touch than aluminium. As for the general features, the combination of aluminium and carbon fibre can be used both for design reasons and for practical purposes — in order to compensate for the sensitivity of carbon to point impacts. In the latter case, the body elements that are most prone to such “troubles” are made of aluminium. In addition, replacing part of the carbon fibre with metal reduces the overall cost somewhat (but increases the weight).

— Magnesium alloy / carbon fibre. A combination similar to the aluminium with carbon described above, adjusted for the characteristics of magnesium alloys. Recall that such alloys, on the one hand, are stronger and more reliable than aluminium, on the other hand, they are somewhat heavier and more expensive. See also above for more details on the properties of carbon fibre. In general, this is a noticeably rarer option than aluminium + carbon: such cases are more expensive, while they have almost no significant advantages.

– Aluminium / glass. Quite a rare and even exotic option; in fact — the only case when glass is used as a material for laptop cases. It is found in certain premium-class models, including fashion ones. The aluminium case (see above) in such models is complemented by an overlay made of special high-strength glass — usually on the outer part of the lid, on the opposite side of the screen. Such glass resists scratches even better than a metal surface, and it further enhances the appearance. However, the practical advantages of such a combination, in fact, are limited to this, so that it is used mainly as an original design move.
