Comparison Acer Nitro 5 AN515-53 [AN515-53-52FA] vs Acer Aspire 7 A715-72G [A715-72G-513X]

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 processor in the SuperPI 1M test.

The essence of this test is to calculate the number "pi" to the millionth decimal place. The time spent on this calculation is the final result. Accordingly, the more powerful the processor, the smaller the result will be (this SuperPI 1M is fundamentally different from many other tests).

The clock speed of the RAM installed in the laptop.

The higher the frequency (with the same type and amount of memory) — the higher the performance of RAM in general and the faster the laptop will cope with resource-intensive tasks. However modules with the same frequency may differ somewhat in actual performance due to differences in other characteristics; but this difference becomes significant only in very specific cases, for the average user it is not critical. As for specific values, the most popular modules on the modern market are 2400 MHz, 2666 MHz, 2933 MHz and 3200 MHz. Memory at 2133 MHz or less is found mainly in outdated and low-cost devices, and in high-performance configurations this parameter is 2933 MHz, 3200 MHz, 4266 MHz, 4800 MHz, 5200 MHz, 5500 MHz, 5600 MHz and more.

The presence of a backlight in the laptop keyboard. This feature not only gives the device a stylish look, but also makes the keys more visible than on non-backlit laptops. The specific implementation of the backlight may vary - it depends both on the price category and on the general purpose of the laptop. For example, single-colour lighting is found in both inexpensive laptops and professional ultrabooks. And gaming models may provide advanced RGB backlighting and even the ability to synchronize the backlight.

The backlight colour is usually chosen by the manufacturer taking into account the general specialization of the laptop. Thus, white backlighting is popular in “office” devices - it fits well into a restrained business style and at the same time looks good on its own. Yellow (golden) colour is noticeably less common - mainly among fashion laptops, although there are exceptions. In turn, among gaming models the most advanced type of backlighting is often found - RGB: it allows you to choose the shade as you wish, and besides, a change in colour can signal different gaming and system events. A number of top gaming laptops feature multi-zone RGB backlighting - each zone can be illuminated indiv...idually or in combination with other areas of the keys. One of the simplest options is a 3-zone backlight highlighting the “WSAD” keys and another additional area. A more advanced implementation is the 4-zone RGB backlighting of the keyboard, and the most chic is the 24-zone backlighting or even customizable backlighting for each individual key, visually distinguishing the buttons from others. Gaming devices are also produced with simpler, single-colour backlighting systems - in such cases, the keyboards usually glow red, green or blue. It is these shades that are best combined with the characteristic design of gaming laptops; Moreover, the red glow is usually used in devices with a rather catchy and “aggressive” appearance (and in itself is an important element of such a style), while blue and green are typical for a more restrained design.

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).

The operating system (OS) installed on the laptop as standard.

The OS is the software base, the environment in which the rest of the “software” of the laptop functions. The capabilities of the device and its compatibility with certain software products largely depend on its brand and version / edition. Theoretically, the pre-installed operating system can be changed to another, but in fact this is not always justified. In particular, the pre-installed OS is usually optimally configured for a specific hardware configuration, while other options may not work correctly.

Among the operating systems relevant for modern laptops, it is worth noting, first of all, the various editions of Windows 10 — in particular, Windows 10 Home and Windows 10 Pro(including versions with the so-called S Mode), as well as Windows 11, which similarly have Home and Pro versions. . An alternative is Linux(including the Endless OS version); and Apple installs a proprietary solution on its laptops — macOS. Of course, devices are produced without a pre-installed OS at all (they also include laptops with DOS on board). Here is a more detailed description of these options:

— Windows 10. This OS was release...d in the fall of 2014 as the next update of the desktop OS family from Microsoft and the successor to Windows 8.1 (number 9 was omitted for technical reasons). It introduced many innovations, such as the built-in Cortana voice assistant, the Edge browser, support for multiple desktops, updated Start menu and notification centre, a major update of standard pre-installed programs, etc. In addition, the system also received an edition of Windows 10 Mobile, which gave a high degree of integration between smartphones and PC / laptops; however, the mobile version was generally unsuccessful and was discontinued in early 2020. Windows 10 is paid, its cost is included in the price of the device. Currently, among laptops it can be found in the following editions:

• Windows 10 Home. "Home" edition — designed mainly for undemanding users who do not need special professional features. Windows 10 Home has all the basic features of the system, but lacks corporate tools, as well as the ability to manage the Update Centre and access the computer via remote desktop.
• Windows 10 Pro. An extended edition of Windows 10 described above, designed for use in the professional field and designed for IT professionals and advanced enthusiasts. In addition to all the features available in the Home edition, it also offers a number of professional and corporate tools — in particular, Active Directory, remote desktop, BitLocker encryptor, and a tool for working with Hyper V virtual machines. however, the more advanced Pro For Workstations edition is designed for high-end workstations, and it simply does not make sense to use it in laptops.
• Windows 10 S Mode. “S-Mode” is a specific version of Windows 10 available for both the Home and Pro editions described above. Such solutions differ from the original OS in limited functionality. So, various programs can only be installed from the Windows Store, the ability to install from third-party sources is not available. This results in restrictions on the use of peripherals: for some external devices, special functions may not be available due to the inability to install a proprietary driver (however, manufacturers of such devices are gradually correcting the situation by writing applications for the Windows Store). Only the standard Microsoft Edge is available as a browser, and Bing is available as a built-in search engine. All this narrows the possibilities for using the system, but significantly increases its security and speed. The latter is especially effective with weak hardware: on such equipment, Windows 10 S Mode is much more comfortable to use than one or another original edition. As for security, it is ensured by careful control of applications published in the Windows Store. The creators position S Mode as the best solution for the educational sector, but in general, this edition is well suited primarily for simple tasks like Internet surfing or working with documents. It is possible to switch from S Mode to the regular version of Windows 10 in the appropriate edition for free — however, this action cannot be undone, and most often it leads to significant performance losses.

— Windows 11. The first major system update from Microsoft in the last six years since the release of "tens". The OS has redrawn most of the icons of standard programs and window controls, the lion's share of actions is accompanied by new animation. The main thing in the redesign is the Start menu button that has moved to a place in the centre of the lower part of the screen. Together with the operating system, Android applications debuted in the Microsoft Store. In general, the system can be considered as a big update of Windows 10 with a serious redesign of the interface, rather than a radically new OS.

As before, Windows 11 is divided into two large camps: Home and Pro. More narrowly targeted versions of this operating system (Education, Enterprise, Mixed Reality, etc.) are also being released.

— macOS. The operating system used exclusively in Apple computers and laptops. Until 2016 it was known as OS X, earlier, until 2012 — as Mac OS. In general, it is considered very reliable and stable, and not without reason: there are relatively few computers for this system, which allows you to well optimize the software part for specific hardware platforms. In terms of application, macOS has proven itself as a solution for professional use: working with documents, design, audio and video editing. At the same time, relatively few games have been created for this OS. The system is updated regularly, and updates are free and available for the life of the laptop. In addition, it is worth noting that macOS is increasingly integrated with Apple's mobile operating system — iOS. So, as of 2020, for owners of "apple" technology, in particular, the following features are available: moving tasks from device to device (for example, you can start writing a letter on a laptop and finish on a smartphone); shared clipboard; duplicating an image from a computer / laptop screen to an iPad; using a portable gadget as an interactive graphics tablet for Mac (including in notes); the possibility of voice and text (SMS) communication from a computer / laptop via a smartphone; transferring photos and scanned materials from a smartphone to a computer / laptop; Mac auto-unlock with Apple Watch, etc.

— Linux. Free and open source operating system. Developed and maintained by a community of programmers around the world. It has its own graphical interface and software tools, which is quite sufficient for solving most everyday tasks, and open source code gives experienced users ample opportunity to customize the system and write their own software. At the same time, there are different Linux distributions — both complex and advanced for enthusiasts, and simple and "friendly", designed for inexperienced users (the representative of the second category, in fact, is the Endless OS described below, but it is often positioned as a separate "OS") . In addition, almost no viruses and other malicious programs are made under Linux. In general, this OS is quite enough for most simple household and work tasks, but games and professional software for it are produced noticeably less than for Windows.

— EndlessOS. A free operating system, which is actually a specific distribution of the Linux described above. It has the same basic features and is fully compatible with Linux applications, and Endless OS has two key differences. Firstly, this OS was created for maximum simplicity, clarity and accessibility even for novice users. Secondly, the standard distribution of Endless OS includes more than 100 additional applications and a lot of reference materials — in case the user does not have the Internet or access to downloading applications is limited in speed or volume. However, there is an edition for those who have no difficulties with communication and who would like to independently choose a set of installed applications.

— DOS. Free operating system with minimal functionality: no graphical interface, controlled via a text command line. In fact, in modern laptops, such a system is intended solely for checking the overall performance; for other purposes, the use of DOS is impossible or does not make sense.

— No OS. The absence of any operating system in the laptop. This configuration does not allow using the device out of the box, but it has an important advantage: the user can choose a specific OS and its edition at his discretion, depending on current tasks and the available low-cost. However buying a paid “OS” separately from a laptop can cost more than purchasing a similar device with a preinstalled OS in the same edition; on the other hand, even with this in mind, such an option is often more preferable and profitable than buying a laptop with an unsuitable pre-installed OS.

The list of rarer and/or obsolete systems includes, in particular, the following:

— Android. Free and open source operating system developed by Google. Initially, it was created for mobile gadgets with the appropriate hardware (energy-efficient system-on-chip processors) and touch screens — primarily smartphones and tablets. Android itself is characterized by tight integration with Google services and an extensive set of applications available through the Google Play market; however, some manufacturers create proprietary software shells based on this OS, including support for their own services and software repositories. Specifically, in laptops, attempts to implement Android have not yet been particularly successful, so this OS can be found mainly in single models of transformers and 2-in-1 devices (see "Type"). This is partly due to the fact that this system is mainly entertainment and multimedia and is relatively poorly suited for work use (although the latter is also possible due to the abundance of applications).

— Windows earlier than Windows 10 (from newest to oldest):

• Windows 8 (in Core, Pro and RT editions);
• Windows 7 (five editions);
• Windows Vista (four editions);
• Windows XP.

All these systems are completely obsolete and are not installed on modern laptops. And for devices running Windows 7 and Windows 8, a free upgrade to Windows 10 is available.

— Chrome OS. Another software product from Google, originally created just for laptops (unlike Android). A key feature of Chrome OS is tight integration with web services: for example, until 2016, the system did not provide the installation of additional programs at all — instead, it was supposed to use web applications opened through the Chrome browser. Actually, Chrome is initially the software basis of the entire OS (hence the name). In the aforementioned 2016, it became possible to install Android applications from the Google Play store on Chrome OS. Specifically, laptops based on this operating system (“Chromebooks”), on the one hand, have shown themselves to be the most inexpensive and affordable devices, convenient, in particular, for use in the educational field. On the other hand, the lack of "native" applications can be a significant inconvenience; and software for Android is usually poorly optimized for ChromeOS — for a number of reasons, developers have little interest in such optimization. And the additional hardware capabilities of Chromebooks as a whole are noticeably more modest than those of their counterparts for Windows and macOS. As a result, such laptops are rare, and the prospects for the system itself are rather vague.

— Meego. Completely obsolete free operating system jointly developed by Nokia and Intel; has not been applied since 2013.

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.

The total weight of the laptop — the device itself, without additional accessories (wires and power supply, mice, bags, etc.). For 2 in 1 models (see "Type"), the weight is indicated when assembled, with a keyboard connected.

Nowadays, models weighing less than 1 kg are found even among fairly large devices — 14 – 15 ", not to mention smaller solutions. Laptops weighing 1 – 1.4 kg are also considered very light, 1.4 – 1.7 kg — light, weight from 1.7 to 2.1 kg(more precisely, even up to 2.5 kg) can be called average, up to 3.5 kg — more than average, and a mass of more than 3.5 kg means that this is an advanced gaming or multimedia laptop designed primarily for power, not portability.

It is also worth remembering that when assessing the weight, the diagonal (size) of the device must also be taken into account. For example, 1.7 kg for a 13" laptop is a lot, and a 17" model can be considered very light if its weight does not reach 2.1 kg.
