Comparison Asus Vivobook 17X K3704VA [K3704VA-AU045] vs Asus Vivobook 17X K1703ZA [K1703ZA-AU062]

The specific model of the processor installed in the laptop, or rather, the processor index within its series (see above). Knowing the full name of the processor (series and model), you can find detailed information on it (up to practical reviews) and clarify its capabilities.

The code name for CPU installed in the laptop.

This parameter characterizes, first of all, the generation to which the processor belongs, and the microarchitecture used in it. At the same time, chips with different code names can belong to the same microarchitecture/generation; in such cases, they differ in other parameters - general positioning, belonging to certain series (see above), the presence / absence of certain specific functions, etc.

Nowadays, the following code names are relevant in Intel processors: Coffee Lake, Comet Lake, Ice Lake, Tiger Lake, Jasper Lake, Alder Lake, Raptor Lake (13th Gen), Alder Lake-N, Raptor Lake (14th Gen), Meteor Lake (Series 1), Raptor Lake (Series 1). For AMD, the list looks like this: Zen 2 Renoir, Zen 2 Lucienne, Zen 3 Cezanne, Zen 3 Barcelo, Zen 3+ Rembrandt, Zen 3+ Rembrandt R, Zen 2 Mendocino, Zen 3 Barcelo R, Zen 4 Dragon Range, Zen 4 Phoenix Zen 4 Hawk Point, Zen 5 Strix Point. Detailed data on different code names can be found in special sources.

The clock speed of the processor installed in the laptop (for multi-core processors, the frequency of each individual core).

Theoretically, a higher clock speed has a positive effect on performance, as it allows the processor to perform more operations per unit of time. However, in fact, the capabilities of the CPU depend on a number of other characteristics — primarily on the series to which it belongs (see above). It even happens that of the two chips, the more performant in the overall result is the slower one. With this in mind, it makes sense to compare by clock frequency only processors of the same series, and ideally, also of the same generation; and the laptop as a whole should be judged by the complex characteristics of the system, as well as by the results of tests (see below).

Processor clock speed achieved in TurboBoost or TurboCore "overclocking" mode.

Turbo Boost and Turbo Core technologies are used by different manufacturers (Intel and AMD, respectively), but they have the same principle of operation: load distribution from more loaded processor cores to less loaded ones to improve performance. The "overclocking" mode is characterized by an increased clock frequency, and it is indicated in this case.

For more information about clock speed in general, see the relevant paragraph above.

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 result shown by the laptop's graphics card in 3DMark06.

This test primarily determines how well a graphics card handles intensive workloads, in particular, with detailed 3D graphics. The test result is indicated in points; the more points, the higher the performance of the video adapter. Good 3DMark06 scores are especially important for gaming laptops and advanced workstations. However, it is difficult to call them reliable, since measurements are made on video cards with different TDPs and an overall average score is given. Thus, your laptop can have either more or less than the specified result - it all depends on the TDP of the installed video card.

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.

Maximum laptop operating time on a single battery charge, without recharging. In this case, usually, the operating time in the maximum energy saving mode is implied: disabled wireless modules, minimum screen brightness, a small load on the processor, etc. Accordingly, the time of actual work on a charge is usually noticeably less than this indicator. Nevertheless, it can be used both for a general assessment of the battery life of a laptop, and for comparing it with other models. And choose work laptop ( from 7 operation hours) or with more powerful battery (from 11 operation hours).
